24 hours of dark best for what?
Yes, if growing photoperiod plants you go to 12/12 to stimulate flowering.
If growing auotos, stay at 18/6 the entire grow cycle, veg and flowering.

Should I Scrog? Confused!My garden seems healthy despite me. Guys I'm confused as to what I should do. Plans are to ScrOG at 18" (which I have never done) with a screen that is 3' x 4'. This screen would cover the entire container area plus about 4" over around the edges. Should ScrOG or just let grow?4y ago

First grow tips and strains pls?Looking at starting my first grow, I have a 120x120x200cm tent, and a 1000w LED light. What auto strains would you recommend for a complete beginner? Any tips in general would be great too. I'm hoping to have 8 plants, but generally quality is more important to me than quantity.Setup. Strain - Autoflowering

Erratic light cycles for the first weekAny experience with keeping a seedling in 12/12 to begin with, then switching over to 18/6 after the first week? Because I did that this time for tech reasons, and I do wonder if I produced a hermie. My own notion is that it will just set me a week back perhaps. Anyone know tho?6y ago
