My new idea (I think) for a self watering/wicking container

[willyb]

I operate on the "KISS" Principal, also into "Low tech" Need to be away from my tomatoes at times.

Conditions:

I garden in zone 3a
I get spent mushroom compost for $15 a heaping pickup load close by. It is steaming when I get it.
I have a small greenhouse

What I think I want to do after reading much on self-watering/wicking container tomatoes:

Use a rubber-made type container or build one from plywood lined with poly. Most online systems I see are too busy, impractical or unnecessarily complex. Simple, low cost and practical are the key elements here.
Install a water intake pipe c/w wine cork level float. (I have a few wine corksJ)
Fill water to the brim with de-chlorinated water c/w calcium, hydrogen peroxide, and some seaweed/fish emulsion.
Place top on container that has 2” hole (or more holes for more plants) bored in it.
Make 2” diameter wick from rolled burlap or cotton towel
Wife, being the quilter and seamstress she is, will sew me 5 gallon containers from filter fabric (Good for root aeration and cheap)
Set containers over top of holes
Thread wick from water reservoir to hole in plant container.
Cut wick with scissors into segments and spread high into plant strata
Fill plant container with tomato amended Mushroom compost (adjust PH as needed)
Plant tomato in pocket of potting soil in mushroom compost so as to not burn roots, let roots ease into compost.
Add a mulch or plastic to top of soil
Place containers in greenhouse on ground, north side, will also function as thermal mass
Let indeterminate tomatoes vine up trusses
Go prospecting for a week and not lose sleep over tomatoes drying out.

Am I wrong?
Will the wick wick enough to meet the plants water needs?

Thanks for your input/feedback/ideas.
