2 Lampen
Ich habe mir von Amazon eine Lampe bestellt wahrscheinlich wird sie nicht die Superleistung haben aber ich dachte mir falls ich mal Blüte mache und ich doch noch ein paar Samlinge habe könnte ich diese trennen. Was haltet ihr davon ? Momentan dient sie nur als Unterstützung

Anyone have any experience with the Light Rail movers? I have 2 of the Light Rail 4.0 systems each in a 4’x8’ tent. I’ve been trying different motor speeds and pause times, just wondering what others do for there pause timings and motor speeds? Cheers 💨

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?

Contemplating putting 2 plants outside. I have 8 in a 3x3 with Mars hydro tsw2000. It’s pretty tight in there. What do you guys think? Is 8 too many for the size and light? Or should I just leave them as is? I think the the pots are 3 possibly 5 gallon.
