Heh, I'll trade you 5' x 5' for 2' x 4'!I read years ago they experimented by taking a highland Columbian strain, and brought it down to sea level, and you couldnt even tell it was the same plant!!!!!
Also, im only using 5 x 5 out of the 45 x 45.
Thanks for that info.If memory serves, last grow, at the highest, EC was 2.1-1100-1150ppm in the water. dont know what runoff was, though they were healthy all the way through.
I don't use "legacy light levels" but I kept fairly close to "legacy nutrient levels" with 0.6 and 0.8 in veg then 1.2 and 1.8 in flower. One of the impacts was that my plants weren't getting to 1kµmol until day 35±. After working with chatGPT to improve my grow processes, I'll be increasing my EC levels to pretty much the levels recommended by the manufacturer (Jacks 3-2-1).
How is that working out?I have 2 box fans on high. On one side of the space I have one Box Fan up in the air, blowing between the canopy, and the bulb. The other is located in a window on the other side of the space. And also an open window 30 feet behind Box Fan #1, and a roof vent, not far off.
Temps vary at the hottest. 88f, if 100f+ outside. Most consistant temps daytime are about 84f. At night they go down to 77f-80f. This is in veg. I flower at night and temps vary 77f-84f. Average is probably closest to 80f.
Ive also had Artificial Intel, figure out how long, and what height to deliver 1.81w sq/m of uva/b, using 2 Solacure 32w Flower Power 4ft bulbs.
The latest study, 2024-published jan 1 2025 on UV/B came from Berlin, and they used several different intensities ect, of UVA/B
They determined that 1.81w sq/m, is the best way to supply uva/b, to marijuana using artificial lighting, and not affect yield, or do great plant damage.
AI determined that 2x 32w Solacure Bulbs, at 24 inches above canopy, need to only be run-17 minutes, MAX- to deliver 1.81w-sq/m, over my 5 x 5 area.
No argument from me. I run 1 change per minute, have an oscillating fan running across the top, and a couple of USB fans on the top of the res facing up. The fans on the plant are running just enough to keep the air moving.As Ive said before.
Really, the first thing I try and establish, before I even start, is adequate fresh air exchange. I have made this priority one, for 40 years. All bets are off , on the use of high umol, if ya aint got no fresh air exchange. It is my first challenge to a grow room.
