Looks ok. Using bottom range 301b leds, kind of like spider farmer and mars hydro... Not tightly packed if I'm being honest. Would be good for a 3x3 - 4x4. I wish you luck in your future grows

Eyeball and advise on my set up, and is this seedling stretching?
Is my set up good until my humidifier comes? (using inflow air from in-line fan with a tray of water for humidity for now). I set up an additional light because I was concerned that this bad boy was stretching and want to provide some extra light for lower canopy later.

Колличество света
Подскажите., почему во всех гайдах и пособиях пищут что автоцветам нужно на цветении 500mmol/cm2 а фотопиродным 700, в то время как реально под солнечным светом растение в ауте получает 1400-1600. Почему не дать столько же света растениям в индоре?

Hps mixed with mars hydro 600 yield?
Hey all! So i been thinking about ways to cut heat of course lol. So I’m thinking about getting a mars hydro 600 and running it with my 400w hps at 250w on the dimmer. Do you guys think I will yield about the same as if I was just running the hps on super lumens?

Light pointed at white wall for supplemental lighting?
Does it makes sense to have a small 300W COB LED pointed at the white flat painted wall for supplemental lighting? If I point the light directly at the plants I would surely burn them but have no space to move back.

Lower lighting at switch to 12/12?
Do you typically want to lower your lighting when you switch to 12/12? I'm a little confused about what is meant when they say to have a 12" light distance for flowering and 18" for veg. Does that mean lower to 12" at the switch to 12/12, or just maintain a min 12" distance?
