From what I've heard the plants in hydro setups can get quite large, but I'm not going for anything that big, since I'm just using CFL's to flower. As for the nutrients, I went to my local hydro store the cheapest A & B Veg base nutes possible, I believe the entire purchase set me back like 20 bucks. I don't have anything to check PPM's, so I'm going by recommended dosage and just monitoring my plants. I'll start using micro nutes when I flower, but I'm all about doing things for as cheap as possible right now.
I'll probably grow indoors until I can harvest outdoors, just to keep me in some free smoke till then, but I dunno, I don't really like wasting plant limits on low producing indoor plants, so I might cut it back to only 2 indoor plants or so by August-September in case Johnny Law desides to pay me a little visit. And the plants in the DWC are definately staying in water their whole life, but I think after these plants, i'm gonna put the hydro setup away till winter, since I don't have AC and it gets nice and hot here in SoCal during the summer. Too much effort to keep the water cool, so DWC in winter, soil grows in summer I think.
Ya know, I really have no idea, they're different strains and really have drastically different genetics. Thats the glory of bagseeds! I guess when the trichome Milky:Amber ratio is correct for me, I like about 20-25% amber usually, but who knows, I'm hoping I can get some dried by April 11th so I can take some homegrown dank to Vegas.
