I have 7 - 4'x8' Hydronic planter bins that have been modified for soil planters ..
along w/ 5 well built planter stands .. $35 each ( includes 1 bin & 1 stand + cedar for each) or $200 for the whole lot.. There is some pre-cut 1x8 cedar for at least 5 bins that have been disassembled that are in good usable condition to extend the depth of the bins.. Proven to grow a lot of fresh produce.
