Do not switch back your lights to anything more than 12 hours or your photo period plants will respect that photo period and go back to vegging stage. Keep on the great care! Happy smokes!

Secondary Lighting Would there be any sort of reason I shouldn't add a second less powerful light to the side of my tent? My thought is if my goal is getting more light to the lower growth wouldn't that be a good course of action?

Lighting question I am running the Viparspectra 450w LED as my light for 4 autos in a 2x4 space. I am worried this isn’t enough, especially because of its lower levels of red. Should I upgrade to something stronger like a Mars hydro 600 or 1000 before flowering start?Or if not Mars something else?

qu'elle est le plus important à prendre en compte le nombre de lux ou le PPFD/DLI lux, ppfd, and dli. While doing this, I realized that it’s hard to have a ppfd between 500 and 1000 for the seedling phase without exceeding the famous 7000 lux. We’re more like approaching 25000 lux if we want to reach the desired ppfd for this phase. How do you do it?
