HYDROPHONICS

don't fucking use milk jugs... those will expose the roots like fuck AND they can break really easily..

go to your local hydro store and buy drippers, pots, hydroton, rock wool cubes, nutrients, all that good stuff..

you will have your 20 plants budded in about 4 months if u do it rite..
if you stick with the dirt..

at the end of the 8 months it took to bud that, they would probably only be 10-15 plants left beccause of those damn milk jugss..
