Dean's speedy earthtainers. I'll just call them speed-tainers.
Notice the sandwich baskets work as support.
Some kind of board top. He left the edges open for water/dirt crossover. This may mean too much water crosses over. We'll just do some experimenting.
By the way, I just wanted to reiterate that Dean has not read any of the plans for Ray's original design(s). He took my explanation of what I saw and riffed on that. When he read my last post he was a little amazed at how professional Ray's earthtainers look. Considering that he was working from my verbal explanation I think he did a great job.
Also, many people have a personal problem growing things in plastic. I just want to add that you can do this with a 5 gallon bucket made of food grade plastic and other similar materials. I am just VERY CHEAP. These three tubs were made for @$4 each. Some people spend up to $50 making an earthtainer. I'm not that invested, just curious.
