Haven't transplanted yet, have 5 gal drain pots. Thinking about trying one or two in a three, not sure though. And roots original mix. Strains I have right now are jetfuel, skywalker OG, Snow White, and wreckage. Wreckage is be one I'm worried about, seems a little like fruit punch though so it probably trains well. Oh and the area is pretty much a full room, 12x8 roughly.I've never heard of a light like that? Doing indica and sativa together is asking for trouble Imo.
You'll need to get something to lift the indica pots up as the sativa will stretch much more.
So much more info your missing. What size area you in? What medium? What strains?
You def on the right path that more doesn't mean more yield.
Not yet, gonna keep them 18/6 for now. Might buy them a smaller grow CFL instead of dimming the 1000w for veg.
Screen / tying and turning will probably be my best bet, don't really have the time to have them recover if I can avoid that. Could try mainlining but never done with a sativa.
Mainlining is something should be done from early on usually from seed. Clones are harder to mainline if possible at all since most clone nodes stack unevenly.
