no these are the bottom buckets 1 have 3 more 5 gal buckets

the 3 inner buckets have 1/4 holes drilled from 1/2 inch up from the bottom 2 the 10" mark from the bottom i have them spaced about 3/8" to 1/2" apart all around. in the bottom of the bucket i have drilled 1/8" holes spaced about 3/8" apart.(it has around 150 to 200 holes) in that i am putting a 6" air stone then putting in 1/3 of my potting mix(50% general potting soil with 50 perlite) the putting another 6" air stone then another 1/3 of the mix then 1/4 inch construction sand then potting my clone with the remaining 1/3 mix the top with 1/4" construction sand. the bottom buckets each have 2 6 inch air stones that sit in the nutrient solution after each watering. oh ya i have a 6" net pot under the inner bucket for space and to hole the 2 airstones down.

i got this idea from zandor off of the grow report #8. everyone if you dont dl his grow reports yet you are really missing some great shit. this is probably one of the best dirt designs i have ever seen.
