Epsilon v2 Plan, 6g per watt goal

[amsterdamgreenman]

Epsilon Protocol v1.1 — 3×3 SOG Grow Bible (Autos, 300 W)​

Goal: Ultra‑high efficiency and yield in a 3×3 ft (0.91×0.91 m) tent using 36 autoflowers in a 6×6 SOG grid under ~300 W LED, CO₂ enrichment, living‑soil hybrid nutrition, and AI‑assisted environment control. Updated to include strain selection, canopy layout, and harvest‑flow design tailored to the 2025 rotation.

---

0) North‑Star Metrics​

• Yield per watt (lamp only): 4.0 g/W achieved (baseline), target 4.5–6.5 g/W.
• Yield per square foot: 148 g/ft² achieved, target 170–220 g/ft².
• Uniformity: emitter‑to‑emitter flow ±5%, PPFD map ≥70% within ±15%.
• Harvest flow: staged front→back, right→left access.

Principle: Photon capture × (CO₂ × VPD × root O₂) × uniformity × uptime = grams.

---

1) System Overview​

• Tent: 3×3 ft, access front & right only.
• Canopy: 36 autos in 6×6 grid, strain layout optimized for stretch, finish, and access.
• Light: ~300 W bar LED, 24/0.
• CO₂: Tablet/bucket generator, AI‑controlled 1000–1200 ppm.
• Airflow: 2 oscillating fans above canopy (corner‑mount), 2 Multifan S5 under canopy.
• Irrigation: 16 mm ring main, dual 2 L/h emitters per pot, fine disc filtration.
• Reservoir: 50 L sealed, aerated; 50/50 carbon‑polished dehu condensate + tap.
• Automation: AC Infinity AI controller (temp/RH/CO₂/VPD) + smart irrigation timer.

---

2) Environment Targets​

• Leaf temp: 27–29 °C veg/early, 26–28 °C mid/late.
• VPD: 1.0–1.2 kPa veg → 1.2–1.4 kPa bloom.
• CO₂: 800–1000 ppm veg; 1000–1200 ppm bloom.
• Placement: sensor at canopy center, shaded, gently moving air.
• Access flow: early harvest strains placed at front/right for staged removal.

---

3) Lighting Strategy​

• Target PPFD: 700–950 µmol/m²/s canopy average.
• DLI (24/0): 60–80 mol/m²/day.
• Placement: prime strains (Velvet, Twilight, Cherry) centered; stable workhorses (Zkittlez, BBOG) edges.
• Reflectance: use bright tent walls + optional side curtains.

---

4) CO₂ Integration​

• Bucket + tablets → tubing from above canopy.
• Controller logic: 950–1100 ppm veg, 1050–1200 ppm flower.
• Exhaust pulse logic prevents dumping enrichment.
• Staging: CO₂‑responsive strains (Twilight, Cherry) center canopy for longest exposure.

---

5) Airflow​

• Above: 2 oscillators corner‑mounted, angled across canopy.
• Under: 2 Multifan S5 diagonals, angled up.
• Exhaust: top back corner; intake opposite low.
• Goal: turbulent mixing, no dead zones.

---

6) Irrigation​

• Ring main racetrack: 16 mm rails 10 cm from walls, joined front & back.
• Feed point: mid‑bottom with optional trim valves.
• Emitters: 2 × 2 L/h per pot via 4 mm T, opposite pot edges.
• Flow demand: 144 L/h total (~2.4 L/min).
• Filters: coarse mesh + 120‑mesh disc.
• Pump: 25–40 W, 1500–2000 L/h, 2–3 m head.
• Flush valves: bottom corners, weekly purge.
• Bypass: for microbes/teas.

---

7) Reservoir & Water​

• Fill source: 50% dehu → carbon → res; 50% tap via valve.
• Aeration: airstone or gentle recirc.
• UV (optional): pre‑res only.
• Maintenance: Cleanse/HOCl between runs, not during microbial feeds.

---

8) Media & Biology​

• Base: Terra Pro Plus + worm castings, frass, lime, fish/blood/bone, perlite.
• Mycorrhizae: Great White at sow/transplant.
• Topdress: veg wk3–4, bloom wk5–7.
• Microbes: Tribus weekly; Mammoth P weekly pre‑flower → late; molasses 5 mL/L weekly via bypass; coconut water once early/mid bloom.
• Caution: avoid mixing microbes with Athena Cleanse.

---

9) Nutrition Timeline (with Dark Cycle Flavor Optimization)​

• Weeks 1–2: water + light Tribus.
• Weeks 3–4: veg topdress, silica to wk6, molasses biweekly.
• Weeks 5–6: bloom topdress, Mammoth P weekly, molasses weekly, coconut water once.
• Weeks 7–8: repeat bloom, Mammoth P, molasses weekly, stop silica wk7.
• Weeks 9–10: taper, add second coconut water.
• Weeks 11–12: water only, increase VPD for density.
• Rescue: Cal‑Mag only if symptoms show.

---

10) Canopy Management​

• Planting grid: 6×6, 15 cm centers.
• Training: minimal LST, early tuck, selective defol, light lollipopping wk4–5.
• Defol cadence: small weekly sessions, maintain airflow lanes.
• Grouping: strains grouped in rows for even canopy; stretchy at back, compact mid, showcase front.

---

11) Strain Layout & Harvest Flow (v1.1)​

• Back rows (6 & 5): Blueberry Ghost OG (stable mid‑finishers), + a couple Zkittlez on Row 5 edge to break wall.
• Mid rows (4 & 3): Row 4 = all Cherry Alien (mid‑finishers). Row 3 = all Zkittlez (early‑finishers).
• Front rows (2 & 1): Velvet Drip (early), Twilight Zlush (late), with Zkittlez swapped into Row 1 front edge for early harvest ease.
• Access logic: early strains front/right; late strains tucked deeper.
• Harvest order:
  • Day 75–80 → Zkittlez + Velvet (front/right).
  • Day 80–85 → BBOG + Cherry.
  • Day 85–90 → Twilight center/front.
• Reasoning: early chop clears path, late finishers enjoy better airflow/light.

---

12) Commissioning & Runbook​

• Commissioning: leak test, catch test (±5% flow), flush 10–20 s, sensor verify, CO₂ ppm hold, PPFD mapping.
• Daily: check AI controller graphs, res level, visual plant check.
• Weekly: flush ports, bypass for microbes, fan check, airstone clean.
• Phase adjustments: re‑map PPFD post‑defol, adjust VPD/CO₂.

---

13) Troubleshooting Matrix​

Symptom	Likely Cause	Fast Check	Fix
Dry pot	Clogged emitter	Flow test	Swap emitter; flush lines
Weak corners	Pressure imbalance	Catch test	Adjust trim valve; confirm ring link
RH spikes	Overwater	Pot weight, leaf feel	Shorten runtime; boost under‑fans
CO₂ drop	Exhaust purge	Ppm graph	Adjust fan hysteresis, injection point
Slime in res	Light leak/stagnant	Lid/airstone check	Reseal, clean, UV pre‑res

---

14) Harvest, Dry, Cure​

• Harvest passes: 2–3 waves aligned to early/mid/late finishers.
• Dry: 18–20 °C, 55–60% RH, 7–14d.
• Cure: 58–62% RH jars, burped, tracked.
• Post‑mortem: note phenos and canopy behavior for layout v1.2 refinement.

---

15) Expansion & Data Logging​

• Expansion: bump pot size to 1.5–2 gal; add slim sidebars if PPFD drops at edges.
• Logging: watt draw (power meter), PPFD/DLI snapshots, irrigation volumes, CO₂ ppm averages, harvest wet/dry weights.
• Metrics: always report g/W (lamp) and g/kWh (whole room).

---

16) Visual Canopy Map​

Orientation: Row 1 = front (accessible); Row 6 = back. Column 6 = right side (accessible).


Legend:

• BBOG = Blueberry Ghost OG (Mid finisher)
• Zkittlez (Early finisher)
• Cherry Alien (Mid finisher)
• Velvet Drip (Early finisher)
• Twilight Zlush (Late finisher)

Grid Layout (Rows back→front):

	Col1	Col2	Col3	Col4	Col5	Col6
Row 6
Row 5
Row 4
Row 3
Row 2
Row 1

Access flow:

• Front + right edges (Row 1, Col 6) harvested first (Zkittlez/Velvet).
• Back/left (BBOG + Cherry) mid-harvest.
• Central Twilight last.

Epsilon V1 pre crop - Dry yield > 1200g

am i the only one thinking this is all impossible? Nice pic, but 4 g/W is science fiction. Physics disagrees. Impressive canopy, but let’s be real — 4–6 g/W from a 300 W LED is pure fantasy land. Even NASA’s plant labs can’t break 2 g/W with full CO₂ and perfect conditions. Looks great though, just not physically possible at that efficiency.

3-4 g/w is actually the scientifically theoretical limit. Doing sog and scrog with a completely controlled environment is the only way to achieve it. Me personally have never achieved that. I get an avg of 1.6 -1.9 dry g/w and yes I run a CO2 emitter and control my environment. But I am only doing a couple plants at a time. You can tell he has his grow area stacked. I'm not sa

Saying anything to stand on his claims. I appreciate seeing his grow and the data provided.

 

[amneziaHaze]

I saw many 3g/w grows but they used airconditioning that was same power or more than the lamp. Your probably thinking total power used teoretical limit we are talking just about lamp g/w

 

[Randyy]

But you good sir absolutely got what it takes to make that a reality.

So far it is only a claim, there is no proof that 6g per watt is a possibility.

 

[JIMKSI64]

So far it is only a claim, there is no proof that 6g per watt is a possibility.

Much like the claim that I can put 1.5 liters of water into a 1.0 liter bucket the 6 gm per watt will be " unobtainable using current science "
All you need to do is to expand our knowledge of the weak and strong forces and learn to manipulate them.
Outside of that...........

I don't think that is a fair comparison because turning 1.5L into 1L is impossible for sure, because if you compressed that 1.5L into 1L then it wouldn't be 1.5L anymore, it would be 1L.

Trying to push the boundaries of yield per watt is not the same, it's just trying to do something that hasn't been done before. Who knows, maybe it is possible, maybe not. We don't know for sure. But I agree that it seems unlikely.

Liter is volume soo... and water changes volume with temperature sooo

And yea there is a huge difference with 1 plant in 3x3 and 30.just the difference in yield feom main top and side tops makes it possible

New led lamps and lamps from 5 years ago are allsoo hugly different

And when dis nasa or anybody try to achive max g/w???

I personally have achived 1.5 with a crapp setup soo 3 should be easy.

 

[closettrapper217]

I’m here looking for pics of this fat canopy wya ? Lol

You completely missed the point... soooo

I get it your saying that sience knows exactly how many photons becomes grams.but it doesnt know that.

You will have to check out the v1 grow diary.

Nope, she gets it.
The property I was referring to is a universal constant rule that the universe has placed on us, you can not compress a liquid.
O you can put it under compression but you can not press one more atom of water into a 1 liter bucket.

You will find from time to time that there are physical properties that you may not ignore. Such as conservation of energy. O that's gunna be a big one for trying to hit 6 grams per watt.
You see we already know many of the physical limits places on converting light into energy and producing carbohydrates to build vegetation. Many studies have found the LIMITS of transperation of plants. The energy required to evaporate liquids from the surface of a plant are known as are the limits to these that are not set by grow style or environmental control they are set by the universe.
Right now I think you should stop using the words I think.
Start using the term ' I feel ' cause science does not seem to be part of your equation.

 

[THCosmic]

Science is ever evolving, which is why so much is "theory" and not fact. Theoretical limits are based on the current understanding of science at that time. What were the theoretical limits before LED technology? Then LEDs blew up in the growing industry and new theoretical limits were achieved. Now LEDs are getting even better!

Simple example everybody can agree that 2.4g/w is possible.for that you use 12h autos use 24h meaning double the amount of energy available.case closed


Plants genetics evolve evwry day we all had one of those wonder plants that produced 3 branches instead of 2 or did double speed compared to rest

First off, you completely missed the point as well. I agree that 1.5L of water will never fit in a 1L bucket. Also why are you talking down to me? Why can't I say that I think something? and you say that I should say that I feel instead... Am I not talking nicely to you and other people??? If you wanna talk down to me then I can be rude to you as well asshole!

Talking about the Universal Laws... You have no clue who you are talking to.... loser

Okej now that you have that out of your sistem explain me the universal law? I didnt go to collage

I wonder why a 24h plant cant produce more than 24h plant

This post is fantastic. This lovely gentleman is sharing what most people would keep secret. And for those of you just outright saying oh it's impossible well then you are in fact calling him a liar. He's already done it. With everything he said in the way he said it you think this guy's a liar. I would say definitely not. And just like any of the ceilings that we hit in different things like for instance running the mile. There was a barrier no one could beat it. Now we have blown past it and people continue to do it faster and faster.
I for one am extremely grateful for to DrDankHands for taking the time and effort to share this great knowledge.
Cheers

I don't believe this is the place to argue information, more or so to learn from each other. Anyone can post what weight they are setting goals and trying to get. If information helps another grower, who cares. There are so many factors to growing and light these days produce more µmol/watt then the hps. And there are more factors to being able to max your grams per watt. Strain/ environmental control/ grower / setup. If someone sets all the information they have for someone to replicate to either test wether they are wrong or right. If you did his grow to a tea you then could tell us if he is lying or providing useful information to help get to the point of making a better setup for newer growers/ experienced. Also it doesn't look like he is doing a commercial grow. So having a few plants is easier to take care of and run these tests. If he has kept track of all his data and provided it, that is technically science.
