Fenton AW200SE, paired-fan, GrowCam, and air-treatment operating schedule

September 13 AW200 + AeroLight 240 W Installation

The owner has hung the AW200 and new AeroLight 240 W (VSL-AL240) side by side, leveled them further after the photographs, and applied the latest plant layout. Independent suspension allows different clearances for taller plants. Confirmed intensities are AW200 at 45% and AeroLight 240 W at 38%. The two-foot return panel stays out; the divider Mylar stays.

Use the two-light equipment record for exact dimensions, masses, and independent suspension from four ceiling hooks, and the current placement guide for the later four-table display. Four E25 paths serve the two lights and two canopy fans. The owner confirms an 18-inch plant-tip reference and the same 13 h 15 m total cycle for both lights, including 15-minute sunrise and sunset transitions at the start and end. Exact clock times remain unrecorded. Keep the reported percentages and current positions provisionally while checking actual plant exposure. The dated ramp below does not replace those reported settings.

September 9 AW200 Record — Before the Replacement Order

On September 9, the owner identified the installed light as the AW200 with tunable spectrum, at 60% for a reported 13.25 hours daily, with quarter-hour sunrise/sunset transitions. Exact clock times, the division of ramp and steady-output time, and current spectrum mode were not supplied. The last recorded 18-inch clearance remains a baseline to remeasure, not a fresh September measurement.

At that time, a Diamond Mylar foam-board return closed an approximately two-foot gap toward the room. The September 10 decision removed it from the plan; the September 11 plan keeps that end open. That earlier bird's-eye view put the window right, white wall bottom, divider Mylar top, and return panel left. The September placement proposal covers all 30 pots and marks unmeasured exposure and table-fit assumptions.

The dated AW200SE identification, 45% setting, and 8:00 a.m.–8:00 p.m. instructions below are retained as earlier planning/history. They do not override the owner's September 9 settings. No new timed ramp is prescribed without the current program's clock times and plant response.

Earlier schedule and operating history

This historical schedule covers the VIVOSUN AW200SE, two AeroWave E6 Gen2 pole fans, GrowCam C4, reflector placement, the three confirmed GrowHub E25 controllers, the TABYIK DH-CS01 dehumidifier, the Levoit Core Mini-P air purifier, and the 2026 collection in Fenton, Michigan. It covers the 2026 move indoors, the revised light acclimation, paired airflow, time-lapse recording, room-air response, pot layout, rotations, local daylight, and the 2027 return outdoors.

The collection moved indoors early on Friday, July 31, 2026, after its first RO-water watering and drainage. July 31–August 2 are equipment-shakedown days at the planned Week 1 settings. The formal light ramp still begins Monday, August 3, so the later height and power-change dates do not shift.

All height measurements are from the LEDs to the tallest cactus or succulent tip inside the direct grow-light footprint, not to the table, pot rim, soil, or peripheral money-tree canopy.

Calendar at a glance

Fenton outdoor cutoff

The permanent move was completed early on Friday, July 31, 2026. The original outdoor-cutoff rule was to move the collection inside for any of these conditions:

• a forecast low of 50°F or colder;
• two consecutive forecast nights below 55°F; or
• a forecast near 53–55°F combined with rain, saturated pots, or strong cold wind.

One isolated dry night around 51–54°F is unlikely to destroy the collection, but bringing the plants in overnight is easy insurance. It does not start Day 1 unless they remain indoors in their final positions.

The date is deliberately earlier than Fenton's first frost. Nearby Flint's 1991–2020 normal low reaches 55°F on September 1–4, 54°F on September 5–7, and 53°F by September 8. Houseplant guidance commonly recommends moving tender plants inside when nights repeatedly approach 50–55°F.

July 31 move-in and August 1–2 finishing checklist

1. Check below the top dressing and lift each pot. Water only the dry, ready pots and shared planters with RO water. Soak the root ball, let every container drain for several hours, and empty every tray.
2. Inspect bodies, leaf undersides, areoles, pot rims, drainage holes, and top dressing for mealybugs, scale, spider mites, ants, or other hitchhikers.
3. Wipe the pots and trays clean. If a plant must be rinsed, let it dry before placing it under the lamp.
4. Keep the original individual pots labeled A1–D3. The six August cacti use their recorded E1–F3 labels. The shared rehab cactus planter is #1, the shared succulent planter is #2, the money tree is #3, and the Kiwi aeonium is #4.
5. Arrange the pots using the layout below.
6. Mark the adjustable hanger positions for 18, 20, 22, and 24 in.
7. Set the LEDs 20 in above the tallest living tip.
8. Hang the Mylar flat from top to bottom on the plant-facing side of the black divider. Keep the white wall, window side, front, and top open. Treat the loose floor sheet as a carpet liner, not a spill basin; keep its aisle edge flat and every tray above it.
9. Set the AeroWave's divider-pole mount to the height and diagonal aim in the placement rules below. Secure its clamp, power cord, and E25 cable.
10. Confirm both previously paired E25 controllers, test the AeroWave sweep at Levels 1 and 2, and leave it at Level 2.
11. Mount and frame the GrowCam using the camera and reflector plan. Take one top-down and one front-view baseline photo.
12. Place the temperature/RH sensor at canopy height in open shade, between the plant surfaces if practical, outside the direct fan stream and away from wet trays, glass, Mylar, and the lamp's radiant heat. Reset its all-time minimum/maximum memory if possible and record the baseline.
13. Record the post-Mylar lux or PAR grid and begin or verify the production time-lapse by 7:45 a.m. August 3.
14. After this move-in watering, return to the normal soak-and-dry rule. Do not water again merely because the plants moved.

Confirmed controller paths

Keep the three control paths separate:

The light and both canopy fans retain their own AC power connections. The AW200SE's RJ45 ports are for compatible AeroLight daisy chains, not for either canopy fan. Do not connect a fan to the light with an Ethernet cable or an improvised adapter. Compatible AeroLights can share one E25 through their RJ45 light chain, but AeroWave fans do not directly daisy-chain fan-to-fan. With E25 controllers, each separately controlled AeroWave needs its own E25. Multiple fans instead require separate controller connections, such as the ports or supported splitter arrangement on an E42/E42A-class controller.

AW200SE E25 program

Paired canopy-fan program

VIVOSUN's current manual lists 10 E25/app fan-speed levels, 10 E25/app Natural Wind levels, and 5 oscillation levels for the E6 Gen2. The original fan's E25 was installed and paired in the VIVOSUN app on 2026-07-28. The second fan is an identical E6 Gen2 with its own E25, so the same model-specific scale applies to both; still tune each side independently because distance and aim differ.

The same manual is internally inconsistent about oscillation: its control table lists five E25/app oscillation settings, while its installation section says oscillation must be activated or deactivated with the fan's swivel button. Treat the physical button as authoritative for on/off, use the app's level only if it appears, and test behavior after a power cycle before relying on a timer.

Keep the fixed light and paired-fan window through September 20 so the weekly results can be compared. The seasonal Fenton times begin September 21. Each canopy fan begins 15 minutes after the light and stops 15 minutes before it during a 12-hour light day when its controller supports scheduling.

The current AeroWave manual lists 10 fan-speed and 10 Natural Wind settings under E25/app control, while the product specification table separately lists five Natural Breeze speeds. Use the 10-level E25/app scale documented for the installed controller path, but let canopy movement and even coverage decide whether Level 2 or 3 is appropriate.

The pole fans provide additional cross-canopy circulation. Keep the AW200SE's integrated fan at its lowest gentle Natural Wind setting rather than running all three air sources hard.

GrowCam and reflector program

The GrowCam is independent of both E25 controllers. Its 256 GB microSD card is within VIVOSUN's supported maximum of 512 GB. Insert or reseat the card only while the camera is powered off.

The 24-hour camera test was completed by September 20; the following dates preserve the earlier recording plan. After the final August 2 layout, start the main 15-minute-interval time-lapse by 7:45 a.m. August 3 and end it after the light turns off September 14. Keep the camera fixed for the entire clip. If the app offers a daily capture window, match the initial 8:00 a.m.–8:00 p.m. light period; otherwise a 24-hour day/night sequence is acceptable.

Use the full-height Mylar on the black left divider as the only vertical foil reflector at first. The loose floor sheet is a protective carpet liner rather than a second PPFD panel. The white right wall is already a diffuse reflector; do not cover it unless the post-install light grid still shows a dark edge after wing and pot-position adjustments.

Temperature and humidity readings

The manual temperature/RH sensor is an observation tool, not another controller. Place it near canopy height between the tables, shaded from the LEDs and window, outside either pole fan's direct jet, and clear of Mylar, wet trays, and the glass table. Direct light or contact with a warm or wet surface can distort the reading.

Use its current, rolling 24-hour minimum/maximum, and all-time minimum/maximum displays without turning the hobby into a logging project:

A broad 65–85°F canopy temperature and roughly 30–55% RH are comfortable working observations for this mixed group, not hard targets. Check the placement and room conditions if the 24-hour temperature drops below 55°F or rises above 95°F. If the 24-hour RH minimum itself remains above 60%, the space stayed humid for the full day: improve spacing or airflow and be especially conservative about watering cool, slow-drying pots. A brief RH maximum above 60% is not by itself a problem. The air-treatment decision table adds a sensor-driven response without making the small dehumidifier part of the normal daily schedule.

Air purifier and dehumidifier

These appliances remain independent of the confirmed E25 controllers:

Start both beyond the second wooden table on the open-room side, outside the nominal 60 in plant bay, direct light footprint, and watering area. The three end-to-end surfaces leave no credible appliance bay. Put the purifier on the divider side with its 360° intake open. Put the dehumidifier on the white-wall side with its rear intake facing the open room and at least 6 in of starting clearance. Use separate rigid trays or boards over the floor Mylar, leave 8–12 in between the units, and keep their cords out of the aisle.

The DH-CS01 has one speed and no humidistat. Its advertised 450 mL/day rating comes from a confined 86°F/80% RH test and is not a realistic expectation at the collection's usual 30–55% RH. Do not run it automatically after watering, and stop it once current RH returns to 45–55%. If sustained high humidity does not improve after 24–48 hours, find the moisture source or use room HVAC/a humidistat-equipped unit rather than expecting this mini Peltier appliance to control the open room.

The Core Mini-P filters room air but does not lower humidity or replace the paired fans' cross-canopy circulation. Leave its aroma pad dry. Full placement, commissioning, maintenance, and safety guidance is in the dedicated air-treatment guide.

Paired pole-fan placement and airflow test

Use the installed divider-pole mount:

1. Keep both fans on rigid mounts on the black divider pole. The pole is preferable to fabric, Mylar, the light hanger, or a movable table.
2. Offset the two hubs or vertical angles enough that both intakes remain clear and the fan bodies, grilles, cords, and oscillation arcs cannot collide. The exact heights still need to be measured.
3. Aim one sweep toward the room-side portion of the plant run and the other back across the opposite portion. Let the moving air overlap gently at the center; do not point the fans directly into each other or create a constant narrow tunnel over one row.
4. Keep both sweeps off the variegated moon cactus, monkey tail, woolly cacti, Kiwi aeonium, money tree, and succulent planter long enough to flatten or rock them.
5. Leave intake clearance beside the window and watch for a cold draft after the outdoor season. Reduce or redirect the window-side fan before allowing cold air to blow continuously across the nearest planter.
6. Keep both fans, controllers, adapters, and connections outside watering spill paths. Provide a drip loop for each cable and keep both sweeps clear of the GrowCam cable and Mylar.

A drip loop is a low bend in a hanging cable before it rises into an outlet, adapter, controller, or camera connection. Water following the cable falls from the bend instead of entering the connection. The historical grow-spot diagrams show the safe cable path in the Wiring tab.

Test each fan alone and then both together with a narrow strip of tissue at the closest shared planter, the center of the round table, A1, the B2–C3 center, D3, and the center and far edge of the second wooden table. The strip should flutter intermittently, but plant bodies should not rock, hairs should not remain flattened, loose top dressing should not move, and one pot should not dry dramatically faster than its neighbors.

Paired-fan strength and oscillation decisions

Do not increase fan strength merely because light power increases. Reposition a fan or change the overlap before using more power. With two fans, Level 3 on either E6 is a provisional exception, not a goal; use it only if a documented still-air pocket remains after placement corrections. Level 5 of 5 E6 oscillation is acceptable if a narrower arc cannot reach its assigned zone, but reduce either arc if much of the sweep misses the tables or hits the other fan.

August 14 medium reset and seven-day dry-down trial

The 18 individual cactus-display pots were still losing about 10–20 g/day on day 14 after watering. That measured trend shows the old pot configuration had not reached a stable dry-weight floor. It does not prove that all 10–20 g came directly from the root zone because plant transpiration also changes pot weight.

The owner emergency-repotted P01–P18 (labels A1–F3) into 60% Molly's Succulent Mix and 40% horticultural perlite by volume, measured as three cups Molly's to two cups perlite. Only old medium attached to the roots was retained. This is pot setup 2. Molly's is sold as a complete gritty soilless mix, and its manufacturer also permits mixing in amendments. The added perlite is an intentional lower-retention choice for this indoor collection, not a universal requirement or an error. P19–P22 were not repotted.

Use the following as a trial, not a watering calendar:

1. Use pot setup 2 for P01–P18. Never combine their setup-1 wet or dry weights with the new configuration.
2. Hold the light at 18 in and 45% and both fans at their lowest successful paired settings during the first comparable cycle. Changing another variable would make the dry-down result harder to interpret.
3. The first setup-2 cycle is complete: all P01–P18 Water rows record plain Beauchamp's RO water with no nutrients at 4:22 p.m. on August 26. Wet weights were recorded between 12:14 and 12:20 a.m. on August 27, about eight hours later. Keep that actual interval attached to this cycle instead of treating it as a 30-60-minute drainage snapshot. Reweigh at roughly the same time daily. Use the separate MSU schedule beginning with the next otherwise-ready watering only if growth and dry-down support feeding.
4. The working target is a repeatable stable dry baseline in four to seven days. Seven days is a review threshold, not an instruction to water.
5. If a pot still has a clear downward trend after day 7 on two cycles, check blocked holes, water in the tray, top-dressing depth, an oversized pot, and uneven airflow before changing the mix again.
6. If a pot reaches its stable floor in two or three days, watch plant firmness and check readiness sooner. A fast dry pot is not helped by daily sips; a ready cactus still gets one complete soak followed by another dry-down.

The manufacturer's product page describes Molly's as a complete, freely draining soilless medium that still retains some moisture, and says growers may mix it with other amendments. University of Minnesota Extension recommends thorough watering through the drainage holes, discarding excess water, and allowing cactus and succulent media to dry completely between waterings. The observed curve in this room decides whether the added perlite meets the seven-day target.

Dimming controls verified on this setup

VIVOSUN lists 25%, 50%, 75%, 100%, and off for “Manual Mode/Grow Hub.” It separately lists 25–100% for the VIVOSUN app, but does not state the app's increment size.

On 2026-07-24, the installed AW200SE/E25/VIVOSUN app combination was tested and confirmed to accept every whole-percent setting from 25% through 100%. The 5% changes in this schedule are therefore available on this setup. This records the hardware, firmware, and app combination tested that day.

Dated six-week acclimation and first steady week

The verified 1% control makes it possible to use a smooth ramp in which most weeks change only one variable. If any step causes fresh bleaching, hard tan patches, or unusual surface heat, use the recovery rule instead of advancing.

The Fenton sun times are rounded to the nearest 15 minutes and are context, not the E25 timer during the ramp.

Do not advance merely because the next date arrived. Remaining at a taller distance or at 50% is a successful outcome if new growth is compact and normally colored.

The outdoor-acclimated plants should not need the gentlest possible start. However, if a plant has spent more than about two weeks in weak indoor light before Day 1, place it at an edge or on a lower stable surface so its tip is effectively 22–24 in from the light for the first week. A local placement change is easier than changing the whole collection for one plant.

Manual-control fallback

If E25/app control is unavailable and only the published 25% and 50% presets can be selected, use distance to soften the jump:

Final pot layout

The tape-measure set from 2026-07-31 changes the planning geometry:

1. The divider-to-wall bay is 36 in wide and about 60 in long.
2. The two wooden and round glass tabletops are all 18 in above the floor.
3. Put the 24 in round table at the window end and the two identical 16 × 13 in wooden tables toward the room. Keep all three separate and end to end along the approximately 60 in length, with their centerlines beneath the long axis of the fixture. They do not fit side by side across the 36 in width. Their 24 in diameter plus two 16 in wooden-table depths uses about 56 in of the bay length, leaving only about 4 in before real gaps and leg interference. Move the air-treatment devices beyond the nominal bay rather than squeezing them into that remainder.
4. Center the approximately 26 in wing-tip width of the AW200SE in the 36 in bay. This leaves about 5 in from each wing tip to the divider/wall when the fixture is centered. The physical fixture width is not the same as its light footprint; keep the wings standard or wide during the ramp.
5. Leave enough space between the table edges that they do not transfer wobble or pinch a monkey-tail stem.

The historical browser grow-spot diagrams show the room, tables, fan sweep, camera view, clearance, and riser measurements.

Original wooden table — A1–D3

The A1–D3 values remain permanent plant IDs; they are not coordinates. Arrange the 12 pots in the three-column by four-row pattern that actually fits the wooden table. Looking from the room toward the window:

This is a height-first starting plan with light-tolerance exceptions. Aim to bring the main starter canopy into roughly the same 8–9 in band above the wood, not to force every tip onto an exact plane:

• A1 stays direct in the gentler outer position; keep its palest side away from the fixture center.
• A3 is visibly shorter than B2 in the tape photos, so A3 moves to the tallest riser while B2 uses only the shortest riser. Give A3 a support and do not use the tall stand if its attached saucer rocks.
• C1 and D1 stay direct in the outer column because they are medium-height, moderate-light plants. The probable Euphorbia hybrid does not need the highest tier.
• B3 stays direct because its raised monstrose growth is already in the taller starter tier. Recheck its highest living point rather than the end of a sideways crest.
• The two raised columns occupy the stronger part of the wooden table. Start with the table centered on the long axis of the fixture. If the measured light center misses the wood, fine-tune the fixture laterally within safe wall/divider clearance rather than moving a sensitive pot onto a taller riser.
• Shared planters: the rehab cactus planter is #1 and the succulent planter is #2; A4-B4 and C4-D4 remain historical cross-references only.

Second wooden table — provisional August layout

The E/F and numbered mappings are confirmed, but these rows remain provisional positions—not a claim that the current pots are still arranged this way. Looking from the room toward the window:

The six August cacti use 4 in pots. September 26, 2026 correction: the owner confirmed that F2 / P17 Boobie cactus uses a normal 4 in pot; the earlier 3 in description was incorrect, and no new repot was reported. The Chamaelobivia is also in a 4 in pot. The Kiwi aeonium is in a 5 in pot and the money tree is in a 6 in pot. This is a tight 16 in-long dry fit, so leave a pot off the table temporarily if rims overlap, a saucer overhangs, or air cannot pass between plants. Add no riser until each tabletop-to-tip height and the final clearance are recorded. The money tree's height is not the reference for cactus fixture clearance.

The six Mountain Crest plants received on August 28 have 2026-08-29 Ruler height/width measurements: P23 1.25 × 1.15 in, P24 1.0 × 2.55 in, P25 1.35 × 2.75 in, P26 1.8 × 1.6 in, P27 0.5 × 1.2 in, and P28 1.3 × 1.7 in. Those are plant dimensions, not maintained grid coordinates or measured plant-to-light clearances. The owner-entered live tracker records 4-inch current pots; all six use the same round 4 × 4 × 3.7-inch pot model. Use temporary edge placement without inventing risers or precise coordinates. 'Black Widow' starts at the gentler variegated edge, Royal Flush keeps separate leaf-cycle watering, and indoor-only 'Coconut Crystal' gets the brightest and coolest practical succulent position rather than the warm center of the cactus canopy. Later placement is recorded in the current guide; the September 20 medium record is approximately 80% Molly's / 20% added perlite, recalled rather than measured.

Orient the shared planters as follows:

• Put the older mixed planter on the divider/left half of the round table. Keep the pale side of the variegated blue torch facing outward toward the divider, and let the monkey tail trail over the open room-side arc between the wooden table and wall cables. Dry-fit the stem path before rotating the planter.
• Put the succulent planter on the white-wall/right half of the round table with the echeveria side facing inward toward the fixture axis. Keep the golden elephant bush and taller kalanchoes from shading it; prune them later if orientation no longer solves the problem.

The GrowCam photo taken before the risers shows these shared planters reversed. Swap them when installing the risers: older cacti toward the fixture/divider side, succulent planter toward the white wall.

Keep both shared planters directly on the glass. The measurement photos put the tallest older-planter tip at about 12.5–13 in above the glass, the succulent canopy at about 8–9 in, and the individual starter tips at roughly 4–7 in above the wood. Because all three tabletops are 18 in high, the general formula simplifies to:

needed lift = round tabletop height + shared tip height - wooden tabletop height - individual tip height

needed lift = 12.5–13 in reference tip - individual tip above wood

For leveling the starter pots against one another, use the more useful working formula:

starter lift = 8.5 in target canopy - individual tip above wood

Then choose the available riser height closest to that lift. The browser layout's calculator does this comparison. The 8.5 in target is provisional; adjust it after measuring every pot directly.

Use the four assignments above as the photo-derived starting layout. They keep every raised tip below the shared reference while putting A3 on the largest lift and B2/C2 on the smallest. Put each riser across one physical row under the two named pots. The tops are only 2.95 in wide and 7.87–9.05 in long. Two 4 in pots are the practical maximum; three will not fit safely. Center each attached saucer over the strip and press gently at several rim points. If either pot rocks, tips, slides, or crowds its neighbor, use the stand for one pot only or leave that row direct. Do not stack the acrylic stands, and do not lower the whole light toward a short plant while the tallest cactus is already at the scheduled clearance.

Rotation and inspection times

Use one simple weekly routine:

The first scheduled rotation is Sunday, August 9. Repeat it August 16, 23, and 30; September 6, 13, and 20; then continue weekly using the current seasonal off time.

Rotation means turning a pot in place, not moving it into another light zone. Do not automatically trade edge and center pots. If one side of the fixture later proves consistently weaker, swap only plants with the same light-zone rating and document the change.

What the schedule means in PPFD and DLI

The official 18-inch, 100% reflective-tent map has a minimum of 573, a 25-point mean of about 707, and a center of 856 µmol/m²/s. The values below scale that map linearly with dim percentage and convert it to a 12-hour DLI. They are planning estimates, not measurements of the future open table.

These numbers are deliberately based on the full map rather than VIVOSUN's separate single specification of 691 µmol/m²/s at 12 inches. The two official datasets do not reconcile, and reflective tent walls raise edge readings. Expect an open table to have lower and less uniform edges.

At the planned 50–55% steady range, the tent-map estimate covers much of the collection's working 10–22 mol/m²/day range. The 55% setting is an optional increase for healthy plants, not a requirement. Horizontal placement supplies the rest:

• Put the rainbow hedgehog, Astrophytum, Old Man of the Andes, Indigo Wave, golden torch, and the greener side of the blue torch nearer the stronger center zone.
• Put the variegated moon cactus, Dragon's Egg, and the pale side of the blue torch toward an edge.
• Keep the remaining plants between those zones.
• Raise short high-light pots on stable risers. Do not lower the entire fixture toward them while a tall cactus is already 18 in away.

The full plant-by-plant ranges remain in the AW200SE research guide.

Height-adjustment rules

Height is adjusted during acclimation and becomes a maintained clearance after September 13.

1. Mark the adjustable hanger positions for 18, 20, 22, and 24 in once the table is installed.
2. Check the tallest tip weekly during active growth and at least monthly otherwise. Raise the lamp enough to restore 18 in as that plant grows.
3. If canopy heights differ by more than about 6 in, use stable risers under shorter plants rather than moving the lamp closer to the tallest one.
4. Do not lower below 18 in during the six-week ramp.
5. After the ramp, do not lower below 16 in without a real PPFD or repeatable lux map at every plant height.

Recovery rule for too much light

If fresh bleaching, yellow-tan hard patches, papery tissue, or unusual surface heat appears:

1. Raise the light to 22–24 in.
2. Reduce intensity by 10 percentage points, such as 55% to 45% or 50% to 40%. If E25/app control is unavailable, use 50% at the greater distance; use the 25% manual preset if new damage still appears.
3. Hold that setting for 10–14 days.
4. Judge only new damage or new growth; old scars will not reverse.
5. Resume with one change at a time after the plant is stable.

Rule for too little light

If new growth remains narrow, pale, weak-spined, widely spaced, or strongly leaning after at least two weeks at 50–55% and 18 in:

1. Move that plant inward or raise its pot.
2. Confirm that another plant is not shading it.
3. If at least three center plants still show the same response, increase by 5 percentage points, up to at most 60%, at 18 in.
4. Hold each supported increase for two weeks before considering another change. If E25/app control is unavailable, measure first rather than jumping directly from the 50% manual preset to 75%.

Sixty percent is the provisional ceiling for the mixed collection—not a hard limit on the hardware. At 18 in its tent-map center estimate is already about 514 µmol/m²/s and 22.2 mol/m²/day over 12 hours. Do not use 75–100% as the default simply because the fixture offers it.

Fenton seasonal daylight after acclimation

VIVOSUN's Sunrise/Sunset option fades the AeroLight up at the beginning of a programmed light cycle and down at the end. The published E25 material does not say that it automatically looks up astronomical sunrise or sunset, and it does not document the fade duration. Treat it as a transition effect inside the schedule, not as a location-aware daylight service.

The earlier plan proposed a seasonal timer change beginning September 21, keeping light power and fan strength steady. The last reported two-light program remains 13 h 15 m; the table below is an archived proposal, not confirmation that these timer changes were applied. Times use Fenton coordinates 42.7978° N, 83.7049° W, follow local daylight-saving time, and are rounded to the nearest 15 minutes. Summer light days longer than 14 hours are capped at 14 hours to avoid adding unnecessary indoor DLI.

Each pole fan runs inside the light window. For light days of 12 hours or less, start it 15 minutes after the light and stop it 15 minutes before the light. On longer days, center an 11-hour-30-minute fan period inside the light window. This stays below the AeroWave manual's 12-hour daily-use condition for its stated service-life and warranty expectations for both identical E6 Gen2 units.

The astronomical calculations are planning values. Atmospheric conditions can shift observed sunrise or sunset by roughly five minutes, which is irrelevant after rounding to 15-minute controller settings.

At 18 in and the documented 50% setpoint, changing the day length changes the tent-map DLI approximately as follows:

Those seasonal changes remain inside a useful broad range for much of the collection. Keep gentler and variegated plants at the edge, especially during long summer programs.

2027 return outdoors and outdoor-day override

After a winter under the lamp, the collection must acclimate to outdoor light again.

Keep the collection indoors throughout the August 3–September 20, 2026, ramp. Routine outdoor trips during those seven weeks would add an unknown amount of sunlight and make the weekly comparisons unreliable.

Sun and lamp exposure add together. Keep the active light and fan programs during the initial ramp, or their current seasonal programs afterward, but manually skip unnecessary indoor light and fan time:

Never add “make-up” hours after the programmed off time. If the outdoor exposure is hard to judge, choose the lower-light option; one modest day is safer than stacking a full outdoor day with a full indoor DLI.

Final table calibration

Recorded on 2026-07-31:

• occupied bay: 36 in wide by about 60 in long;
• all three tabletop surfaces: 18 in from the floor;
• round glass top: 24 in diameter;
• two identical wooden tops: 16 × 13 in each;
• AW200SE: about 26 in from wing tip to wing tip;
• tallest shared-cactus tip: about 12.5–13 in above the glass; and
• current starter-tip band: roughly 4–7 in above the wood before risers.

After installing the risers, record:

• the occupied table width and depth;
• individual tabletop-to-tip heights for the six August cacti, Kiwi aeonium, and money tree;
• light-to-tip distance for the tallest and shortest plants;
• wing position;
• whether walls or reflective surfaces are nearby; and
• a phone-lux or PAR reading at a 3 × 5 grid across the plant footprint after the left-side Mylar is installed;
• both pole-fan distances to the nearest plant, hub heights, vertical angles, app program values, and oscillation levels; and
• whether both E6 Gen2 units at Level 1–2 reach the closest shared planter, round-table center, A1, B2–C3 center, D3, and both zones of the second wooden table without moving top dressing or rocking plants;
• GrowCam lens height, distance, angle, and whether all labels and growth tips remain in frame; and
• whether the 24-hour time-lapse test exported and played correctly;
• final Core Mini-P and DH-CS01 positions beyond the nominal plant bay, intake clearances, and cord paths; and
• the first appliances-off baseline plus any 12–24-hour dehumidifier response check that the sensor actually triggers.

The exact tape photos are indexed in assets/measurements. These measurements replace the earlier assumed table geometry without changing the ramp's basic order or seasonal timer dates.
