I'm starting a grow from seed,(I have 15 varieties ) As far as lighting goes I've never heard a definetive answer as far as flouresent vs MH & HPS. I have a 400 watt mh and a 400 watt mh/hps.I also purchased three 5 gallon hydro kits (for the mothers) over kill I guess. I planned on using the MH overhead and maybe 4' cool white flouresents for side lighting inside two closets apx. 3 x 5. I'd like to have a SOG. As far as the clones go can I start them on regular cool whites and then switch to MH at a certain point and at what stage/size. And do you think it's worth going totaly hydro? And at what size/stage should I switch to 12&12 w/ hps? I haven't grown since the early 70's and my mom always found them before I ever saw any bud. Also what lighting cycle should I keep the mothers on? Also what size I keep the mothers croped to? I think I'm on the right track,I also thought about using a Co2 system, the sugar/yeast dealy. Also what's better bat/seabird guano or worm castings. Sorry about the number of questions but I figured do it all at once.
