I read your super aerogarden thread before I ever came across this one. I actually have an aerogarden and I started out on this thread searching aerogarden and came across all your threads, of course your aerogarden thread will lead you to this DIY thread somewheer in there and that's how I ended up in here, I originally started in your aerogarden thread though,lol.
Why are you going to the flower stage in the 5gal buckets, more room for the roots ??? I don't have room for that kind of set-up, what do you think about this....... For my very first ever grow inside, I was gonna start them in my aerogarden, whichever ones are females, I will transplant them (most likely 2 or 3) into my big bubbler (your DIY one) and grow them in that until the harvest. Does that sound doable to you ?? I haven't quite figured the lighting yet but I was thinking of the 400W HPS light with the induct cooling for it, then of course I will have to figure out the rest of the ventilation, exhaust, fans, etc... But does my grow sound like it would work with 2-4 plants in your DIY bubbler system ??
