Really inspiring thread here. Beautiful stuff AP, and others.

I have wanted to float an island to grow some lettuce during the heat of the summer when it just suffers in the garden. Curious to hear more from Bill about the practicality of that idea.

I have a large coir mat that I convinced the wife to sacrifice for a floating lettuce island. I was thinking to build a floating framework from 1 1/2 inch ABS pipe, lay 1/2 inch plastic mesh over that, layer of newspaper, then the 2" thick coir mat, and finally a little potting soil for the plants to germinate in.
Is there something I am overlooking in this plan?

cheers fellas-
