Section 12:

Intensity Tables & Quick-Reference Schedules

Use these as load-and-go references for both 4×4 and 5×5 areas (two fixtures, perpendicular or parallel). Values are conservative baselines designed to work in most rooms. If you’ve enabled the Aggressive Profile, see the “Overrides” rows at the end of each table.

 

Baseline Phase Table (12/12 flower)

Phase	Channel	Output / Window	Notes
Weeks 1–2 (commissioned)	Full+Red	50–60% all photoperiod	Mirror top light sunrise/sunset if used. Hold 24–48 h after any change.
	Far-Red	5 min at T0 and 5 min at T12 @ 20%	Pulses only. If stretch appears, remove T0 pulse; keep EOD 3–5 min.
	UV	Off	Do not introduce UV yet.
Weeks 3–6 (build)	Full+Red	55–65% all photoperiod	Increase only if VPD/RH/CO₂ remain stable.
	Far-Red	Keep pulses above; add 1 mid-day window 10 min @ 15%	Add mid-day only after a full week stable. Remove mid-day first if airy lowers.
	UV	Off	Late-phase only tool.
Week 7+ (finish)	Full+Red	50–60% all photoperiod	Don’t chase last-minute gains; protect finish.
	Far-Red	Pulses as above; EOD may extend to 5–8 min @ 15–25% if finish lags	Extend EOD before touching F+R intensity.
	UV	5 min @ 10% mid-day; after 3 days stress-free → 10 min @ 10%	Mid-day only. No entry without PPE. Any stress → cut time in half or disable 3–5 days.

Footprint application (both 4×4 and 5×5): two fixtures run the same scene. If the center seam is hot and corners lag, raise both fixtures 1–2 inches or shift outward 1–2 inches before increasing power.

One-Page Wall Card (print)

Photoperiod (12/12 Flower)

• Full+Red: run all day (50–65%). Change in 10–15% steps.
• Far-Red: pulses first (5 min @ 20% at T0 & T12). Add one mid-day 10 min @ 15% only after a week stable.
• UV: late flower only, mid-day, start 5 min @ 10%; extend to 10 min only if zero stress.

Daily checks (log):

• Lower vs upper canopy temp/RH one hour after T0 and one hour before T12.
• VPD during/after FR window; runoff EC/pH on a rep pot.
• Posture, internodes, edges, aroma.

Fast rollbacks:

• Stretch wk 1–2 → remove T0 FR; keep EOD 3–5 min.
• RH spike mid-day → remove mid-day FR; increase airflow/dehu.
• Any UV stress → disable UV 3–5 days; restart at 5 min.
• Acute stress after any change → revert to prior scene, reduce Full+Red −10% for 24 h.

Notes on Calibration & Uniformity

• Two fixtures per 4×4 or 5×5. Start both at the same % and scene.
• If the center seam is bright and corners lag, raise both fixtures 1–2 inches or shift outward 1–2 inches before increasing power.
• Maintain ≥6 inches leaf clearance at all times; re-check after defol or tuck.
• Keep connectors above splash height with drip loops; daisy-chain perpendicular runs fixture-to-fixture, then exit on the dry side.

Section 13:

Integration With Tri-Chan

This section shows exactly how to translate the operating rules into Tri-Chan scenes, schedules, and safeguards. It assumes two fixtures per 4×4 or 5×5 footprint, either perpendicular or parallel, daisy-chained as in Section 4.

 

Controller setup checklist

• Set controller date, time, and timezone. Confirm DST behavior.
• Create a room naming convention: Site > Room > Footprint. Example: DI > R3 > FP-4×4-A.
• Calibrate sensor inputs. Place a temp-RH probe at lower-canopy height near the footprint center seam.

Scene architecture that scales

Use a small set of reusable scenes, then assign scenes to footprints. Do not hand-tune by fixture.

Base scenes

• B50, B55, B60: Full+Red at 50, 55, 60 percent. FR Off. UV Off.
• FR-Pulse: add 5 min FR at T0 and T12 at 20 percent.
• FR-Emerson: FR-Pulse plus one mid-day FR window 10 min at 15 percent.
• UV-5 and UV-10: current FR scene plus UV 5 or 10 min mid-day at 10 percent.

Bundles

• Short-Cycle, Quality-Max, Yield-Max bundles from Section 11 map to these base scenes. Keep bundles identical across footprints to avoid drift.

Scheduling rules in Tri-Chan

• Photoperiod: match top lights. If top lights use a 10–15 min sunrise and sunset, mirror those ramps on Full+Red.
• Pulses: schedule FR at precise times relative to T0 and T12. Example: T0–T0+5 min and T12−5 min–T12.
• Mid-day windows: anchor at the middle of the photoperiod. Example: T0+360 min on a 12 hour day.
• UV windows: schedule inside no-entry blocks. Add a visual alarm and door sign at the same time.

PPFD and uniformity workflow

• Use a handheld PAR meter at lower-canopy height for 5 to 9 points per footprint: four corners, four edges, center seam.
• After placement, set Full+Red to B50. Log average PPFD at lowers. Most rooms will not chase a specific PPFD number at the lowers; the target is uniformity and plant response.
• If edges are low versus center, move fixtures outward 1 to 2 inches or raise 1 to 2 inches before increasing output.

Day-by-day tweak cadence

• Monday and Thursday are edit days. Make spectrum or timing changes only on those days.
• Hold each change for 24 to 48 hours and log lower-canopy temp, RH, VPD 1 hour after T0 and 1 hour before T12.
• Never change Full+Red, FR, and UV on the same day. One lever at a time.

Footprint assignment examples

4×4 footprint

• Week 1–2: assign B50 + FR-Pulse.
• Week 3–6: assign FR-Emerson once Gate B passes.
• Week 7+: assign FR-Emerson + UV-5, extend to UV-10 if Gate D passes.

5×5 footprint

• Same sequence. If the center seam is bright, raise both fixtures 1 to 2 inches or shift outward 1 to 2 inches before changing scenes.

Alarms and rollbacks baked into Tri-Chan

• Alarm set A for commissioning: RH spike during FR window, temp delta after Full+Red change, CO₂ under target for more than 15 min.
• Rollback macro: one button that returns the footprint to the previous scene version and disables UV for 72 hours. Use this if any acute stress appears.

Troubleshooting inside Tri-Chan

• If a scheduled window does not fire, check three things in order: schedule enable, interlock status, and channel mapping.
• If both fixtures do not respond equally, check the daisy-chain link and confirm both fixtures are assigned to the same scene. Replace or reseat the link cable on perpendicular runs first.

Commissioning templates to copy

Template 1: Baseline

• B50

Operator SOP for Tri-Chan (print)

1. Load the correct bundle for the footprint and phase.
2. Verify sensor readings and interlocks at T0, mid-day, and T12.
3. Log daily checks and any alerts.
4. Only edit scenes on scheduled edit days.
5. If any stop condition triggers, press Rollback, notify a lead, and record the event.

Section 14

Environment and Nutrition Sync

Goal: make sure the added under-canopy photons translate into growth and quality, not stress. Align climate, CO₂, and irrigation with the spectrum moves you are making.

First principles

• Light raises demand. Match water, minerals, and gas exchange before you raise intensity or add new windows.
• Change one lever at a time. Fix climate first, irrigation second, spectrum last.
• Verify at the lowers. Place at least one temp-RH probe at lower-canopy height and compare to the top.

Target climate by phase

Use these as safe starting bands. Hold steady for 24–48 hours after any change.

Phase	Canopy temp (lights on)	RH	VPD	Notes
Early flower (wk 1–2)	76–80 °F	58–65%	0.9–1.2 kPa	Keep transitions smooth at lights on and lights off.
Mid flower (wk 3–6)	74–79 °F	52–60%	1.1–1.4 kPa	Watch RH during FR windows and after Full+Red bumps.
Late flower (wk 7+)	72–77 °F	48–55%	1.2–1.6 kPa	Protect finish. Keep VPD steady during UV windows.

Transitions

• Start fans and dehu a few minutes before T0 to avoid RH dips or spikes.
• If VPD drops at T0, remove the lights-on FR pulse first and increase dehu lead-in.

CO₂ alignment

Phase	CO₂ ppm	Notes
Early flower	900–1,100	Stable delivery to the lower canopy matters more than top-line ppm.
Mid flower	1,000–1,200	Hold steady during mid-day FR windows.
Late flower	800–1,000	Quality focus; avoid large swings while UV is active.

Tips

• Verify CO₂ at lower-canopy height near the center seam, not only at the top sensors.
• If CO₂ dips during FR mid-day windows, correct distribution before touching light.

Irrigation sync with photon changes

Light increases raise transpiration first. Prefer frequency changes before EC changes.

When you increase Full+Red or add an FR window

• Add a small irrigation event or pull one event earlier in the day.
• Recheck runoff EC. If runoff climbs while plants look “dry,” frequency is too low for the new load.
• If runoff falls and color fades, keep the new frequency and raise input EC modestly within your normal range.

Shot size and dryback

• Keep shot sizes consistent; adjust the number and timing of events to shape dryback.
• Aim for predictable daily dryback. Avoid large late-day drybacks that collide with end-of-day FR.

Late flower

• Maintain consistent frequency. Do not chase last-minute yield with big EC jumps.
• If you add UV, do not change irrigation on the same day.

Dehumidification, airflow, and latent load

• Expect higher latent load once under-canopy photosynthesis wakes up the lowers.
• Watch dehu duty cycle during the first hour after T0 and during any mid-day FR window.
• Add gentle, continuous airflow across the lower canopy. Eliminate dead zones behind stands and along rails.
• If RH rises more than 5 points during a window and does not recover within 10 minutes, shorten or remove the mid-day FR window and increase airflow before making new light changes.

Fast decision tree after any light change

1. Check lower-canopy temp/RH/VPD 30–60 minutes after the change.
2. If VPD fell or RH rose, increase airflow or dehu. Do not raise light further.
3. If climate holds but runoff EC rises and plants look “dry,” add an irrigation event.
4. If climate holds and runoff EC falls with fading color, raise input EC modestly.
5. Only after climate and irrigation are stable should you consider the next spectrum step.

Nutrition guardrails

• Match demand, not a fixed number. Use runoff EC trend and plant look to steer.
• Nitrogen: avoid late-phase N spikes. Let Full+Red and EOD FR handle finish timing.
• Potassium: ensure adequate K through mid and late flower to support density when under-canopy light is active.
• Micronutrients: UV can increase demand in sensitive cultivars; watch edges and color. Do not add UV and raise EC on the same day.

Common interactions and fixes

Issue	Likely interaction	Fix order
RH creep after adding FR mid-day	Latent load increased under canopy	Add airflow at lowers, increase dehu lead, remove mid-day FR first if unresolved.
Tip nip the day after a light increase	Frequency too low vs new load	Add a small irrigation event; hold spectrum steady 48 hours.
Pale color with normal runoff EC	CO₂ distribution weak at lowers	Fix CO₂ delivery at lowers, then reassess before raising EC.
Aroma thins after adding UV	UV dose too long or plant not ready	Cut UV time in half or disable 3–5 days, then restart shorter.

 

Operator checklist (print)

• Confirm VPD bands by phase before any spectrum change.
• Verify CO₂ at lower canopy during the first hour of the day and mid-day.
• After any light change, log lower vs upper canopy temp/RH and runoff EC within 60 minutes.
• Change irrigation frequency before EC.
• Do not adjust Full+Red, FR, and UV on the same day.
• If a stop condition triggers, roll back to the prior scene and correct climate or irrigation first.

Dialing environment and feed to the light is what makes the spectrum work.

Section 15

Validation & Recordkeeping

Goal: turn good runs into repeatable runs. Capture just enough data to prove cause-and-effect, spot drift early, and make rollbacks clean.

 

What “validated” means (pass/fail gates)

A program is validated for a footprint (4×4 or 5×5, two fixtures) when all are true for ≥14 consecutive days in a phase:

• Plant: target structure (internodes in spec), healthy edges, consistent turgor, lowers building.
• Climate: lower-canopy VPD within phase band ≥90% of photoperiod; no RH spikes >5 pts that persist >10 min during FR/UV windows.
• Irrigation: runoff EC trend tracks plan (no sustained rise from under-watering); dryback curve consistent.
• Scenes: no unauthorized edits; one change at a time with 24–48 h holds.
• Quality/Yield proxy: at least two objective markers trending positive (e.g., bud uniformity score, sample mass from set branches, resin visual index).

If any gate fails, pause changes and return to the last validated scene.

 

The Core Log (one page per footprint, per week)

Keep it simple so it gets done daily.

Header

• Site / Room / Footprint ID, cultivar, week-of-flower, scene version

Daily rows (fill at three touchpoints: T0+60, Mid-day, T12−60)

• Scene name + channel % + window durations
• Lower vs upper: Temp, RH, VPD, CO₂
• Irrigation: shots so far, last shot time, runoff EC/pH (rep pot)
• Observations: posture, internodes, edges, aroma (short phrases)
• Action box: change made (Y/N), what, why

Weekly footer

• Fail flags hit? (Y/N, list)
• Pass/fail against 15.1 gates
• Next-week intent (hold / step X) and owner initials

Photo and meter protocol

Standardized visuals and light checks make trends obvious.

• Angles: wide room view, footprint top-down, lower-canopy seam close-up, representative cola side profile.
• Cadence: Day 0 (pre-change), Day 2, Day 7 after any scene change; otherwise weekly.
• PAR spot grid (lowers): 5–9 points (four corners, four edges, center seam) at B50 after placement and any height change. Record mean, min, max, and Δ between center and corners.
• File naming: SITE_ROOM_FP_DATE_PHASE_SCENE.jpg (e.g., DI_R3_4x4A_2025-10-23_Wk4_FR-Emerson.jpg)

Uniformity & overlap quick math

Track before raising power.

• Uniformity index: min/mean PPFD at lowers (goal ≥0.85).
• Center seam bias: center PPFD ÷ average edge PPFD (goal ≤1.15).
  If either misses, adjust placement (Section 4) before increasing Full+Red.

Scene version control (paper + Tri-Chan)

• Version string: B50_FRpulse_v3 → next change becomes …_v4 (one variable per bump).
• Changelog: date, variable changed, rationale, owner, expected outcome.
• Rollback macro: maps each scene to its prior version; use at first stress sign.

KPIs to track every run

Pick a small set and stick to it room-to-room.

Operational

• % of days meeting phase VPD band at lowers
• Avg RH delta during FR mid-day window
• UV compliance: % of scheduled UV windows completed without abort

Crop

• Internode length (mm) on tagged branches (wk 2, 4, 6)
• Lower-bud uniformity score (1–5) from photo rubric
• Sample wet mass from the same tagged branches per week (or trimmed dry sample if feasible)

Outcome

• Harvest timing vs target (days)
• Yield/ft² (or per plant)
• Quality markers (lab if available, or blind scorecard for resin/aroma 1–5)

Experiment framework (A/B safely)

Only one lever at a time. Use the smallest number of test footprints that still gives a read.

• Design: Control (validated scene) vs Variant (single change).
• Minimum duration: 7 days stable unless a stop condition triggers.
• Stop conditions: any stress marker, RH spike unresolved in 10 min, or stretch beyond cultivar norm → immediate rollback.
• Decision rule: predefine success (e.g., +0.2 on uniformity score with no climate penalty) before starting.

Weekly reporting cadence (15 minutes)

• What changed: scene versions per footprint
• What moved: VPD compliance %, RH delta during windows, irrigation events/day
• What plants said: posture/edge/aroma notes, internode snapshots
• Go/No-go: hold, advance one step, or rollback
• Actions: who does what before next check-in

Deliver as a single page with three photo panels (room, lowers, cola).

Compliance & safety audit (UV/FR)

• UV no-entry signage present and aligned to schedule
• PPE available and used when entry is required during UV (rare)
• Interlocks/alerts tested weekly (UV skip if RH above limit; FR skip if VPD low)
• Scene PIN lock intact; change log matches controller history

Archiving & naming

• Folder tree: SITE/ROOM/WEEK_YYYY-MM-DD/
  • logs/ (PDF or CSV), photos/, scenes/ (export), sensors/ (CSV), notes/
• Keep at least the last 3 validated runs for each cultivar as your gold set.

One-page wall checklist (print)

• Lower-canopy probe installed & reading
• Scene version logged before/after any change
• Photos captured D0/D2/D7 after change
• PAR grid (lowers) recorded after placement/height edits
• Daily T0+60 / Mid-day / T12−60 checks completed
• UV/FR alerts reviewed; any skips explained
• Rollback macro verified this week

Handover rules

When shifts change or rooms are handed off:

1. Walk the footprint with the log in hand.
2. Confirm today’s scene and next scheduled windows.
3. Review yesterday’s RH/Temp deltas and irrigation notes.
4. Agree on “no edits” unless a stop condition triggers.
5. Sign off in the log.

Locking validation and records like this makes Sections 11–13 durable and scalable.

Stands and restraints

• Use supplied under-canopy stand or rigid, non-conductive crossbars.
• Strap with UV-stable ties. Fixtures must not slide during irrigation pulls or tucks.

Electrical Planning Notes

Branch circuit sizing

• Treat each Tri-Spec as 150 W continuous load.
• Always verify measured inrush and any manufacturer chain limits; if limits conflict, follow the stricter limit.

Wire and protection

• Use dedicated circuits where possible.
• GFCI where local code or wet-location practices require.
• Keep all connectors above splash height with drip loops.

Power quality

• Maintain PF ≥ 0.96 and THD ≤ 15 percent by staying within rated load and avoiding overloaded circuits with mixed inductive loads.

Heat and latent load impacts

• Added under-canopy photons increase transpiration and dehu duty. Confirm headroom before enabling large groups.

Daisy-Chain and Signal Wiring

Perpendicular runs

• Link fixture-to-fixture across the footprint with daisy-chain cables, then drop to the dry side for mains.
• Use the shortest cable that reaches without tension.

Labeling

• Label each link and channel at both ends, for example: Site-Room-Footprint-Run-Segment.

Best practices

• One continuous chain per footprint when possible.
• Avoid running signal cables in parallel with high-current AC for long distances. Cross at 90° where necessary.

Environmental Ratings and Cleaning

Ingress

• IP66 housings resist directed water. Do not pressure wash fixtures.
• Keep connectors mated and elevated.

Cleaning

• Power down and cool before service.
• Use a soft, lint-free cloth. If needed, a light isopropyl wipe on the lens. No abrasives, no solvents on gaskets.

Storage

• Dry, dust-free, −4 to 140 °F, in original packaging where possible.
