Here are a couple of photos. The first is the the three barrels, the next is a view from the top of the whote barrelI'm using 55 gallon plastic chem barrels from work. I cut the tops out, leaving the rim for strength, wash and scrubbed them (They held glycol and soap). I used two blue ones and one white one. The plants in the white one have more even growth and are about 20% taller than the blue barrel ones. Planted Yukon gold potatoes. My onions in the garden are pathetic.
I'll see about getting some photos this afternoon.
