8 straight days at channel maximum — faulty sensor or a genuine life-safety issue. Verify with a handheld today.
The one-line read. Michael's half of the May 8 diagnosis has largely landed — feed EC went up, the
team stopped chasing runoff on every shot, and substrate EC across the flower rooms has recovered from a 0.6–0.8 collapse
to a 3.2–4.4 working stack. Brittany's half has not: lights-on VPD in every flower room is still below the target for its
phase, the West rooms run 5 °F cooler than the East rooms, and in both West rooms lights-off VPD is higher than lights-on
VPD — the plants are doing their transpiration at night. The deep drybacks Burly is getting (23–33 absolute pp) are being
delivered by the dark period rather than by the day. That works, but it is fragile, it is not what the AUTOMAIT recipe will
assume, and it caps how hard you can steer.
2 · Prior-Commitment Review — the May 8 2026 diagnosis chain2 · Revisión de Compromisos
On May 8 the chain was: Brittany lowered VPD (correct) → transpiration fell → the plants
under-fed at the then-current feed EC → substrate EC collapsed to 0.6–0.8 in veg against a 1.9–2.4 feed → substrate EC below
feed EC pushed root-zone pH to 7.0–7.5 → runoff on every shot, including P1, flushed what stack was left → hungry plants and
Pythium pressure. Five commitments came out of that call. Here is how the last 14 days grade them.
Commitment (May 8 2026)
Verdict
Evidence from 2026-06-29 → 2026-07-13
1. Raise feed EC from 1.9–2.4 to 2.3–2.6, push toward 2.8
NOT STUCK (inferred — see caveat)
AROYA does not expose feed-EC telemetry, so this cannot be read directly and we say so plainly. What the substrate
says is unambiguous: every room's substrate EC has moved up off the floor and the two mature flower rooms are holding
3.2–4.4 mS/cm. A substrate that stacks to 3.9 cannot be fed at 1.9. The raise happened. Confirm the actual number with
Michael in the meeting — the open question is whether it reached 2.8.
2. Stop chasing runoff on every shot (especially P2s)
NOT STUCK
The drip-vs-drain EC gradient is the tell. Flower Westt B1-B4 holds 2.22 mS/cm at the drip position vs 7.45 at the
drain position — a 5.2 mS/cm gradient across the bag. You do not get that gradient if you are pushing runoff on every
P2; runoff would wash the drain end back toward feed EC. Flower Eastt B1-B4 shows the same shape (2.58 vs 3.85).
The stack is being held. Shot counts (4.6–6.6/day in flower) are consistent with maintenance pulses, not flush pulses.
3. Substrate EC ≥ 2.0 in veg; ≥ feed EC + 1.0 in flower
PARTIAL
Flower, mostly met: Flower Eastt B1-B4 closed at 3.59–3.89 (target 3.3–3.6 at feed 2.3–2.6) ✔; Flower Westt B1-B4
held 4.0–4.7 ✔. Flower Eastt A1-A4 (new Wk-1 crop) is at 2.21–2.48 and falling — sitting at feed EC, not above ✘.
Veg, failing: Veg West bled 2.52 → 2.08 through the crop (now 1.84 in the empty bags) and MOM/PROP 2.29 → 1.99.
Both are at or under the 2.0 floor.
4. Mount the drip-drain sensors under the table
NOT VERIFIABLE
Physical mounting height cannot be read from telemetry — this needs a photo or a 30-second look. What we can
confirm: in all three flower rooms with a drip-drain kit, drip-position EC sits below drain-position EC (12404: 2.58 < 3.85 ·
12406: 2.22 < 7.45 · 16868: 1.07 < 2.86), which is the correct orientation — the probes are not reversed.
One watch item: in Flower Eastt A1-A4 on 07-12 drip (3.23) crossed above drain (2.98). If that persists, check that pair.
5. Final-week pre-harvest pull-back to ~1.0 substrate EC
NOT STUCK (with a caveat)
Executed. Flower Westt A1-A4 (Flower Cycle 41) ran substrate EC 2.64 → 1.33 mS/cm across Wk 8 / Wk 9 Flush into
the 07-06 harvest, with drip-position EC down to 0.84 and dryback deepening 27 → 33 absolute pp. That is the pull-back,
done properly. The caveat: ripening began at 2.6 mS/cm, not the 6.0–8.0 restack the phase calls for — so Burly pulled
back from a stack they never built. The flush is right; the restack in front of it is the gap.
The pattern across all five. Michael's levers (feed EC, runoff discipline, flush) are moving.
Brittany's lever (VPD / transpiration) has not yet been re-opened after the May correction — and because transpiration is
what drives uptake, the veg rooms are quietly re-running the May failure in slow motion: 3.8 pp dryback in Veg West,
5.7 pp in MOM/PROP, and substrate EC bleeding back under 2.0 in both. Fixing the veg rooms is a climate job, not a feed job.

Is this a capacity problem or a setpoint problem? The evidence says setpoint on the East side, capacity
on the West side. Flower Eastt B1-B4 demonstrated on 07-11 → 07-13 that it can hold 58–59% lights-on RH at 75–76 °F and
deliver 1.19–1.25 kPa. The West rooms never got lights-on RH below ~63.3% across the entire fortnight, and they sit ~5 °F
cooler — which means the West air handlers are running cold to condense, and still not getting the room dry. To reach
VPD 1.3 at 71.5 °F you need ~52% RH; the West rooms are 12 pp away from that. Raising the West lights-on air temperature by
3–4 °F is the cheapest path to VPD — it lifts saturation pressure without asking the dehumidifiers for more water removal
— and it also lifts substrate temperature (currently 71.5–73 °F in the West vs 77 °F in the East), which is itself suppressing uptake.
Anomaly worth a question. On 07-02 Flower Westt B1-B4 dropped to 69.6 °F lights-on with VPD 0.80
and CO₂ collapsing to 746 ppm (vs a 1300–1430 ppm baseline). That reads like an equipment or door event, not a setpoint change.
Nothing broke downstream — but it is the kind of excursion worth knowing the cause of before AUTOMAIT starts reacting to it.
Dryback is not an irrigation setting. It is the difference between what the plant takes out
and what you put back. Burly is currently getting most of its "take out" from the wrong half of the day.
The inverted VPD profile. In both West flower rooms, lights-off VPD exceeds lights-on VPD
(Flower Westt B1-B4: 0.94 day / 1.08 night · Flower Westt A1-A4: 0.88 day / 1.18 night, rising to 1.31–1.39 in the last four
days). Air temperature barely drops at lights-off (71.6 → 70.9 °F), but RH falls 6–10 pp. The result is a room that is
drier for the plant at night than during the day. That is why the ET rate (P3 dry-down slope) measures 0.74–1.31 pp VWC/hour
in these rooms — the overnight dry-down is doing the work that daytime transpiration should be doing.
Why this matters for steering. P3 is the primary steering lever, and Burly's P3 is deep and
consistent (23–33 absolute pp). But a P3 driven by night VPD rather than day transpiration means:
Uptake and dryback are decoupled. Nutrient uptake tracks daytime transpiration; overnight water loss moves VWC without
pulling much EC into the plant. That is exactly how you end up with a deep dryback and a substrate EC that will not stack —
which is precisely what the new Wk-1 room (Flower Eastt A1-A4) is showing right now.
The bulking room is being generatively steered by accident. Flower Westt B1-B4 is pulling 23.4 pp when bulking wants
12–18 pp. Nobody set that; the night VPD did.
The veg rooms get the opposite problem. Veg West (0.76 day / 0.76 night) and MOM/PROP (0.84 / 0.77) have no VPD
differential at all, so there is no dry-down engine — 3.8 pp and 5.7 pp of dryback respectively, and substrate EC bleeding out.
Coco-specific caution. Burly is on 2-gal Char-Coir coco, not rockwool. Coco has high CEC and holds a
buffer; it is more forgiving than rockwool but it will punish aggressive generative steering with Cal/Mg lockout if the
substrate EC is pushed hard while pH climbs. The May 8 chain (substrate EC below feed EC → root-zone pH 7.0–7.5) is the coco
failure mode, and it is the reason the fix is climate first, feed second: raise daytime transpiration so the plant pulls
the feed it is already being given, rather than raising feed EC into a plant that is not drinking.
Steering intent: generative (Wk 2 Early Gen → Wk 4 Mega Pump) — and the data agrees.
Substrate EC ran 3.25 → 3.89 mS/cm over the fortnight: a real, sustained stack, and the first Burly flower room
to clear the "feed EC + 1.0" bar Cian set on May 8 (feed 2.3–2.6 → target 3.3–3.6; the room closed the window at 3.59–3.89).
Overnight dryback averaged 25.3 absolute pp (73.9 peak → 48.6 trough) with a standard deviation of only 2.1 pp —
that is a tightly-run generative P3 and it sits squarely in the 20–30 pp early-flower band.
Two things to watch. First, the P0 delay collapsed from ~150 min to 69 min on 07-09 and has stayed there — the first
shot is now landing barely an hour after lights-on. In Wk 4 Mega Pump that shortening is a legitimate move toward
vegetative/bulking steering, but it has not been paired with the corresponding dryback relaxation: P3 is still pulling
25–27 pp when the bulking target is 12–18 pp. Right now the room is being asked to be generative overnight and vegetative
in the morning. Pick one. Second, lights-on VPD is finally climbing (1.08 → 1.19–1.25 over 07-11 → 07-13, on the back of
RH falling 67% → 58%) — that is the East side's dehumidification proving it has the headroom the West side does not.
Steering intent: bulking, moving into ripening (Wk 5 +Pump → Wk 7 Coasting) — the data only half agrees.
Substrate EC held 4.0–4.7 mS/cm all fortnight — inside the 4.0–7.0 bulking band, and a night-and-day improvement on the
0.6–0.8 collapse of May. But it is drifting down, not restacking (4.32 on 06-29 → 4.09 on 07-12), and this room flips into
Wk 8 Flush on 07-15. The ripening restack (6.0–8.0) never happened, so the flush will be pulling back from a base that was
never built. That is the single highest-value EC decision on the floor this week.
Dryback averaged 23.4 absolute pp (76.4 peak → 53.1 trough) against a 12–18 pp bulking target — the room is being steered
generatively through bulking. Combined with a lights-on VPD of only 0.94 kPa (bulking wants 1.2–1.4), the picture is a
cool, humid room whose deep dryback is being delivered by the night, not the day: lights-off VPD (1.08) is higher than
lights-on VPD (0.94). The plant is doing its transpiration work in the dark. That inverted VPD profile is Brittany's lever.
Drip-position EC 2.22 vs drain-position 7.45 — drip below drain, which is the normal direction (probes are not reversed).
A 5.2 mS/cm gradient across the bag says the stack is being held, not flushed on every shot: the "stop chasing runoff on
every P2" ask has landed here.
Steering intent: ripening → flush → harvest 07-06. This is the room that closes out a May commitment.
Substrate EC came down 2.64 → 1.33 mS/cm across Wk 8 / Wk 9 Flush, and drip-position EC fell to 0.84 — that is a real
final-week pre-harvest pull-back toward ~1.0, executed. Dryback deepened in step, 27 pp → 32.9 absolute pp, inside the
25–35 pp ripening band, with shots rising to 7–8/day to keep the bag from crashing. Textbook finish.
The caveat is what came before the flush: EC was at 2.6 when ripening began, not the 6.0–8.0 restack the phase asks for.
Burly pulled back from a stack they never built. The pull-back is a genuine win; the restack is the gap.
Substrate readings after 07-06 (VWC 1.7%, EC spiking to 15) are teardown artefacts — bags stripped, probes out of media.
They are excluded from every statistic above. Climate telemetry continues (the room is now empty and being turned).
Steering intent: generative (Wk 1 Transition, flipped 07-08) — too early to grade, but two early
signals are already off. The substrate probes went live 07-09, so this room contributes 4 days of root-zone data, not 14.
Signal one: substrate EC is falling, not stacking — 2.48 → 2.21 mS/cm across the first four days of flower. Week 1
transition is where the stack is supposed to start. At feed 2.3–2.6 the substrate is currently sitting at feed EC, not
above it. Signal two: the shot pattern is erratic — 3 shots on 07-09, none detected on 07-10, 4 on 07-11, none on 07-12 —
with dryback swinging 2.5 → 11.0 → 17.1 → 19.8 pp. Some of that is fresh transplants that are not transpiring yet
(a 2.5 pp dryback on day 1 is a plant that has not woken up); some of it is shots too small to clear the detection
threshold. Either way the room has no stable P0/P1/P2/P3 rhythm yet.
Sensor watch: on 07-12 the drip-position EC (3.23) crossed above the drain-position EC (2.98) for the first time.
Drip > drain sustained is the signature of reversed probes. One day is not a diagnosis — but check the pair before the
room settles into its stack.
Steering intent: vegetative — and the room is over-watered relative to that intent.
Valid crop window is 06-29 → 07-08 (Flower Cycle 44's Veggie Tails left the room on 07-08; everything after that is
fallow bags). Across those days dryback averaged 3.8 absolute pp against a 5–15 pp veg target, on 0–3 detected shots
a day. VWC never left the 58–77% band. In 2-gal coco that is a root zone that is never allowed to breathe.
Substrate EC fell 2.52 → 2.08 mS/cm through the crop, and has kept falling to 1.84 in the empty bags. The May 8
commitment was substrate EC ≥ 2.0 in veg. This room finished the run at the line and is now under it. That is
Michael's item, and it is the same mechanism as May: not enough dryback → not enough transpiration-driven uptake →
the stack bleeds off.
Two hard data flags. The Veg West climate station stopped reporting on 2026-07-06 23:51 and has not come back —
no air temp, RH, VPD or CO₂ for the last 6 days of the window. And the CO₂ channel reads 0–101 ppm, which is not a
physically possible value in an occupied, sealed room. Both are covered in the companion device-health report.

Steering intent: vegetative (mother stock) — under-dried, and there is a CO₂ integrity problem.
B&T Moms 19 (70 plants) and B&T Moms 20 (50 plants) share the room. Dryback averaged 5.7 absolute pp against the
10–20% band Cian gave Michael on 2025-12-08 for mothers. Peak VWC 70.1, trough 64.4 — the bags essentially never dry.
Substrate EC drifted 2.29 → 1.99 mS/cm — the same slow bleed as Veg West, and now below the 2.0 veg floor.
CO₂ is railed at 5000 ppm for eight consecutive days. 5000 ppm is the top of a standard AROYA CO₂ channel and is also
the OSHA 8-hour exposure limit. Either the sensor is saturated/faulty or this room is genuinely at a level people should
not be working in unprotected. This needs a human with a handheld meter today — it is not something a report should
resolve from telemetry.
Steering intent: vegetative (18 h photoperiod, 44-cultivar mother-stock library) — despite the
"R/D Flower Room" name, this room is running an 18-hour day and holding R/D Mom Stock in VEG.
Lights-on VPD is 0.66 kPa — the lowest in the facility, and below the 0.8–1.1 veg band — on 78% lights-on RH. Substrate EC
2.5–2.9 mS/cm, comfortably above the veg floor. Dryback averaged 12.8 absolute pp, which is inside the veg band, but the
distribution is bimodal: 6–15 pp on most days and 27–29 pp on 07-08 / 07-09. Zone dryback spread across the room is
14.4 pp — the widest of any room with a full crop in it. That is either genuinely uneven emitter delivery across the
trays or a probe sitting in a bag that is not on-line. Worth 10 minutes with a hand meter before it becomes an R/D
data-quality problem.
6 · Phase Biophysics — 14-day room environment trace6 · Biofísica de Fase
Select a room with the chips. Turn on Compare mode to overlay several rooms on the same
axis. Every series is a daily aggregate computed from raw ~9-minute AROYA samples, split lights-on / lights-off using the
room's own PPFD profile.
The same chips drive these charts. P0 = activation (lights-on → first shot).
P1 = ramp-up (small shots back to field capacity + first runoff). P2 = maintenance (pulses holding FC, managing
substrate EC via runoff). P3 = dry-down (last shot → next morning) — the primary steering lever, and the one Burly is
running deepest.
Measured from the no-shot decay after the last shot of the day
Shot-count derivation (read this before quoting the numbers). AROYA exposes no irrigation-event
telemetry at this facility — count_irrigation_events returns nothing and there is no drip-volume series. Shot counts
above are derived from VWC step-up signatures: a rise of ≥ 2.0 absolute pp between consecutive native-cadence samples
(~9 min) is counted as one shot. Consequences you should hold in mind:
In the flower rooms the derivation is reliable — 2 GPM emitters, 2 per plant, into a 2-gal coco bag produce
unmistakable 3–8 pp step-ups. Counts of 4.6–6.6/day match the shape of a real P1 + P2 program.
In Veg West, MOM/PROP and R/D the plants are smaller and the shots are smaller — many land under the 2.0 pp
threshold. Shot counts and P0 delays in those three rooms are a lower bound and should not be quoted as fact. The dryback,
VWC and EC figures for those rooms are unaffected and remain trustworthy.
Days showing "0 shots" with a real dryback (e.g. Flower Eastt A1-A4 on 07-10 and 07-12) mean shots below threshold, not
an irrigation outage.
Reading the drip-vs-drain chart. Drip-position EC below drain-position EC is normal — feed enters at
the drip end, the plant strips water out as it moves through the bag, and salts concentrate toward the drain end. A sustained
drip above drain reading is the signature of a reversed probe pair, not of agronomy. Burly is correctly oriented in all
three instrumented flower rooms; the single crossover in Flower Eastt A1-A4 on 07-12 is a watch item, not yet a finding.
Note also that these probes are reported to have been mounted 6–8″ elevated rather than under the table — if that is still true,
treat the absolute drip/drain values as directionally right but biased, and the gradient (drain − drip) as the trustworthy signal.

Action
Priority
Why, from this window's data
Raise lights-on air temp in the two West flower rooms by 3–4 °F (71.5 → 75 °F)
P0
Lifts lights-on VPD from 0.94 to ~1.2 without asking the dehumidifiers for a single extra litre — saturation pressure
does the work. It also lifts substrate temperature off 71.5–73 °F (East runs 77 °F), which is currently suppressing uptake
in exactly the room whose EC will not stack.
Close the day/night VPD inversion — target lights-off VPD ≤ lights-on VPD
P0
Both West rooms transpire harder at night than by day (0.94 day / 1.08 night; 0.88 / 1.18). Your deep drybacks are
being generated in the dark, which moves water but not much EC. Fixing this is what makes the substrate EC stack.
Pull lights-on RH in the West rooms toward 55%
P1
West never went below 63.3% lights-on all fortnight. East proved on 07-11 → 07-13 that 58–59% is achievable at Burly.
If West physically cannot get there, that is a dehumidification capacity finding worth costing — but prove it first.
Raise VPD in Veg West and MOM/PROP into 0.8–1.1
P1
Veg West sits at 0.76 with no day/night differential, MOM/PROP at 0.84 on 73% RH. With no dry-down engine, dryback
is 3.8 pp and 5.7 pp against 5–15% (veg) and 10–20% (mothers). This is why veg substrate EC is bleeding under 2.0 —
it is a climate problem presenting as a feed problem.
R/D Flower Room: 0.66 kPa on 78% RH
P2
Lowest VPD in the facility, in the room holding the 44-cultivar mother-stock library. Low risk today, but it is the
genetics bank.

Why, from this window's data
Restack Flower Westt B1-B4 before the 07-15 flush — substrate EC 4.1 → 6.0+
P0
The room enters Wk 8 Flush on 07-15 and its substrate EC is drifting down (4.32 → 4.09), not restacking. Ripening
wants 6.0–8.0 before the pull-back. Flower Cycle 41 already showed the consequence: a textbook flush executed from a
stack that was never built. This is the single highest-value EC decision on the floor this week.
Four days into flower and substrate EC is falling (2.48 → 2.21), sitting at feed EC rather than above it. Week 1
transition is where the stack is supposed to start. Lengthen P3, cut P2 volume, and let the bag concentrate.

Both are at or under the 2.0 veg floor from May 8, and both are trending down. Do not fix this by raising feed EC
alone — that is what failed in May. Pair any feed change with the VPD lift above, so the plant actually drinks it.
Relax the bulking dryback in Flower Westt B1-B4 — 23.4 pp → 12–18 pp
P1
Wk 5–7 is bulking; the room is being steered generatively (23.4 absolute pp). Shorten P3 / add a P2 pulse. On coco,
sustained aggressive generative steering with a climbing substrate EC is the Cal/Mg lockout path — the same coco failure
mode that produced the pH 7.0–7.5 root zone in May.
Pick a steering intent in Flower Eastt B1-B4 — P0 delay is 69 min but dryback is 26 pp
P2
The first shot moved from ~150 min to 69 min after lights-on on 07-09 (a vegetative/bulking move, appropriate for Wk 4
Mega Pump), but P3 is still pulling 25–27 pp (a generative setting). The room is being asked to be two things at once.
Confirm the actual feed EC number
P2
We can infer the raise landed; we cannot read the value. Tell us where you actually are between 2.3 and 2.8 and the
"feed + 1.0" targets above become exact instead of a range.
What the 14 days say your real strategy is — write the recipe to this, not to a textbook:
You are a deep-P3 house. Flower dryback runs 23–33 absolute pp, remarkably consistent (Flower Eastt B1-B4 holds
25.3 pp with a 2.1 pp standard deviation across 14 days). That is a generative-leaning program and it is working. Do not let
a recipe wizard talk you into a shallow 12–15 pp default.
Your P0 is 100–160 min in flower (before the recent Flower Eastt B1-B4 drop to 69 min). That is a real, deliberate
generative P0 delay, right inside the 120–240 min early-flower window. Encode it.
Your P2 is light. 4.6–6.6 shots/day total, with a held EC gradient across the bag. That is the "stopped chasing runoff"
behaviour from May, and it is the thing most likely to get clobbered by a default runoff-threshold guardrail.
The runoff threshold that stopped you last time: the blocker was a runoff/drain guardrail that conflicted with your actual
strategy — and it did, because a threshold that triggers a shot whenever drain volume falls below target will re-introduce
exactly the every-shot runoff chasing you spent May eliminating. Set the guardrail on substrate EC and dryback, not on runoff
volume. Concretely, for the AUTOMAIT recipe edits:
Dryback guardrail (the primary control): early flower 20–30 absolute pp · bulking 12–18 · ripening 25–35. Let AUTOMAIT
trigger P1 on dryback reached, not on a clock and not on runoff.
Substrate-EC guardrail (the safety rail): floor 2.0 in veg; ceiling by phase — do not let a bulking room ride above
~7.0 on coco (Cal/Mg lockout), and do not let a Wk-1 room sit below feed EC.
Runoff: use it as a reporting metric, not a trigger. If AUTOMAIT insists on a runoff target, set it loose
(5–10% daily, not per-shot) so it cannot fire a corrective shot into a P3 you are trying to deepen.
ASI slider: GEN 1 is the most aggressive (deepest dryback) → GEN 5 neutral → VEG 6–10. Step DOWN for deeper
dryback. Given Burly's measured 23–33 pp, the flower rooms are already living around GEN 2–3; the veg rooms (3.8–5.7 pp)
are effectively at VEG 8–10 and need to come down several steps.
Before you enable anything: archive the dead room 12405 "Flower West A1-A4", and fix the Veg West climate station —
AUTOMAIT cannot steer a room whose VPD it cannot see, and Veg West has been climate-blind since 07-06.

Action
Priority
Why
MOM / PROP CO₂ reading 5000 ppm for 8 straight days
P0
5000 ppm is both the top of the sensor channel and the OSHA 8-hour exposure limit. Either the sensor is saturated/faulty
or the room is genuinely unsafe to work in. Verify with a handheld meter today — do not resolve this from telemetry.
Veg West climate station dark since 2026-07-06 23:51
P0
No air temp, RH, VPD or CO₂ for the last 6 days of the window. Its CO₂ channel was already reading 0–101 ppm before it
went silent — physically impossible in an occupied sealed room.
Archive room 12405 "Flower West A1-A4"
P1
Zero series returned. It shadows the live "Flower Westt A1-A4" (16868) by one letter. A recipe or alert attached to the
ghost fails silently.
Confirm drip/drain probe mounting (under table, not 6–8″ elevated)
P1
Orientation is correct in all three instrumented rooms, but mounting height cannot be read from telemetry. Elevated
probes bias the absolute values; the drain−drip gradient stays trustworthy either way.

Every room's climate series spans 2026-06-29 13:03 UTC → 2026-07-13 12:54 UTC — 14.0 of 14 days, ~2,240 raw points
per room at native ~9-minute cadence. Pulled by stitching public_api/rooms/<id>/chart/ in 2-day windows
(the endpoint caps at 2 days per request). No envelope, no synthesis, no interpolation across gaps.
Flower Westt A1-A4 substrate after 07-06
EXCLUDED
Harvested 07-06. Post-harvest readings (VWC 1.7%, EC spiking to 15 mS/cm) are probes out of media during teardown.
Excluded from every statistic; the climate trace continues and is real.
Flower Eastt A1-A4 substrate before 07-09
NOT AVAILABLE
Room was empty between the 06-15 harvest of Flower Cycle 40 and the 07-08 flip of Flower Cycle 44. Substrate probes came
online 07-09. 4 days of root-zone data, not 14 — every substrate number for this room is provisional.
Veg West climate
DEAD 07-06 → 07-13
Climate station stopped reporting 2026-07-06 23:51 and has not returned. Its VPD/temp/RH figures are computed from
06-29 → 07-06 only. Its CO₂ channel read 0–101 ppm even before it went dark — not a usable value.
MOM / PROP CO₂
RAILED
Pinned at 5000 ppm (channel maximum) for 8 consecutive days. Treated as a sensor-integrity flag, not as agronomy.
Shot counts & P0 delays
DERIVED
No irrigation-event telemetry exists at this facility. Derived from VWC step-ups ≥ 2.0 absolute pp between consecutive
~9-min samples. Reliable in the flower rooms (2 GPM emitters produce unmistakable steps); a lower bound only in Veg West,
MOM/PROP and R/D, where shots are smaller than the threshold. Dryback, VWC and EC in those rooms are unaffected.
Feed EC
NOT IN AROYA
AROYA carries no feed-EC channel at Burly. Commitment 1 is graded by inference from substrate behaviour and is flagged
as such. Ask Michael for the number.
Drip/drain probe mounting height
NOT VERIFIABLE
Reported to have been mounted 6–8″ elevated rather than under the table. Cannot be confirmed from telemetry.
Orientation (drip < drain) is confirmed correct in all three instrumented flower rooms.
Room 12405 "Flower West A1-A4"
NO DATA
Returns zero series for the full window. Excluded. Believed superseded by room 16868 "Flower Westt A1-A4".
Runoff volume / drain volume
NOT AVAILABLE
No drip-volume or drain-volume series exists at this facility. Runoff behaviour is inferred from the drip-vs-drain EC
gradient, which is a directional signal, not a volumetric one. Any recommendation that turns on runoff percentage
needs a manual measurement.
