This stuff is available in rolls in Aldees.  It's meant to water your plants while you're away.  There's no instructions on it whatsoever though.  I imagine it absorbs and retains moisture, are you supposed to stuff it into the bottom of a grow bag or something??

Never used it but I'd guess it goes under pots or trays. Could be used as an inner lining for baskets I guess.

Be a bit troublesome to line a tom bag with it I'd have thought

It's made to draw water out of a reservoir so pots can use it.

Google "oxypot" ( or something like that ) for one way to use it.

Ooops, oxypot is a different thing, led to some interesting forums though :roll: ... try this article @link ehow.com
