Sorry for the turbo post but the system would not let me Edit.
Pic 1, AK-47, @ the chop. The first box I ever built..with a ton of changes, like being able to sink the buckets or tubs thru the floor for a cooler rootmass, and of the real reason...MORE BUD ROOM!!! It's an ugly clunky old thing, but damnit...I love her!!! She has been running one crop after another non stop for 6 years!! Day in day out!! Old shipping crates, torn apart and rebuilt into a useful working part of society!!
Pic 2 my newly designed and box on it's base!! Hollow wall, flow thru design, cheap to make, easy to use, rolles where I need it to. Emergency over flow pan in base, quiet, and it also has run nonstop since I made her last year!!
Pic 3, new box witha Black Thia thats run her course.

Both boxes are fully hydro capable, and each have had hydro crops come from them.
I love PlantBoxing!!
