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!

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.

Lighting cycle for VEG stage. Is 24x7 OK?Hi, Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED Thanks, Mr.STM

Did I start LST too early?At day 22, did I start LST too early? I feel that I may have stunted the growth a little from overheating, but didn't want to wait too long to start training. Also, would a higher-powered light cause less distance between the nodes, and therefore make LST harder/less effective?
