Rebuilt the tent after NegotiatedBubble was kind enough to share his good ideas, I cut a hole in tent ceiling and placed the main grow light in the hole. This displaces a lot of the heat generated and puts it outside the tent where its own dedicated cooling fan can take most of it away, for good measure added 1/2" tempered glass, this allows light to pass through hopefully mitigating alot of heat getting inside. Also added 2 ultrasonic hot & cold humidifiers.
Refurbished soil HVAC system, and increased airflow.
To maximize your yield, always aim for 40 moles, or 40,000,000 μmol, per day. Here is how much PPFD is needed per second for each phase of cannabis growth to achieve the DLI of 40 moles of light per day.
I picked up a Quantum PAR Meter, very happy!😁 PAR Meter will show me how much useful radiation between 4-700nm the plant is getting from any given direction.
Seedling phase (18hr cycle): 200–300 μmol m-2 s-1
Vegetative phase (18hr cycle): 617 μmol m-2 s-1
Flowering phase (12hr cycle): 925 μmol m-2 s-1, (1500 μmol m-2 s-1 @1500ppm co2) (ballpark). Anything above 2000 PPM is harmful to both the grower and the crops.
The tent is currently reaching 3-400umol ms 1s at soil level (42" inches from light) and 1100umol-1300umol @ 25" Inches.

Wow very nice setup. My wife would shit if I bought all that. Plus I can't believe it but I'm a lightweight now when it comes to bud. I grew a Bruce Banner outside last year. 1 hit and I'm done. Cured I got 7 plus ounces and it's way too strong for me. I had to give away most of it away. So this year I have 6 strains all under 20 thc. Going to be a 7th very soon. 3 are high cbd low thc 10 to 14 thc outside plants. Just watched 1 of your videos. You have a serious grow room. Little more than I can get away with. Interested in the blue light, I may have to add another light.
@Natrona, I messed up and managed to get a spider mites infestation near the end of C#6, still had a good harvest but had to harvest a week earlier than I would have liked. I was very excited for Hermeticum but the mites came back with vengeance, topsoil stayed moist once the canopy shaded the medium and I couldn't control it and had to dust the grow. C#7 was a bust so no.
I don't keep as good a record of weight as I should, all I can give is my observation with my eyes, c#6 Asclepius was monstercropped so it makes it difficult to guess what was cropping and what was the electric current if any at all, near the end I was able to visually tell if she had current through her or not.
Asclepius had almost no fertilizer, enzymes yes. Impressive results for a 300 dollar light off Amazon 6th grow, the biggest most dense buds I've managed to grow.
"it accelerates cycles" would be a good way to describe what I witnessed, not increasing size directly for any reason, but everything was "more of" & "faster".
Will need to buy a few new toys before I can play with ideas floating in my head.
