The EarthTainer is a wonderful idea, but over time I think the Rubbermaid totes in the stores will get thinner and thinner (and less and less opaque) as the corporation cuts costs; this may make my tweaks required instead of preventative steps.
1.) After the main tub has been prepared (holes drilled and such) use the landscaping fabric to make an inside curtain from the top of the tote to the bottom in a full circle (if you like the look, feel free to do it on the outside – the black will absorb the heat from the sun).
This curtain should slow the sunlight and algae growth.
2.) Put in your support bench and cover all inside surfaces with the landscape fabric – much like a fabric cup. This should make it easy to pick up the soil as a package (no digging in the fall) and may keep most of the roots out of the water.
3.) Do NOT drill a hole for the feeder tube but cut an upside down U just below the bench level – best on the side facing away from the sun to slow algae and evaporation. This stiff flap stays closed until top up time.
Random tip: drill the ends of the cut so the cut doesn’t turn into a travelling crack as the plastic gets more brittle.
I plan to use a flexible hose (that’s stored away from the sun) to top up the water. I will probably have rain water in a large bucket and use a simple syphon to move the water.
Also: the second cup-like wrapping of landscape cloth will come in handy shortly… I forgot to drill holes in the bench for drainage into the water section. Heh, oops.
