Hi,
Wondering what FF members think?
Re:
fiberglass screen vs fabric type barrier above hydro ( see link below)

Substrate Barrier - Substrate Barrier | Josh's Frogs

Aslo, has anyone any experience with this product? Used with hydroponic gardening. Very cool!

GENERAL HYDROPONICS: CocoTek

GENERAL HYDROPONICS: CocoTek Liners

It is available in pots, block and mats.

GENERAL HYDROPONICS: CocoTek Mats

"Made from natural coconut fibers and bound by organic latex, CocoTek® Mats are designed to lie underneath media containers and can be easily cut to any size. In ebb and flow tables, plant roots will grow through and under the Mats where moisture remains between flood cycles."

I wondering what "organic latex" is ?

Thanks, Lynn
