Styrofoam as a base in a grow stand

[ladyslipper]

Hi Ross, I hadn;t thought of building foam, i was thinking about those foam stands that look like cones. you often see them in hobby shops. is there a difference in foam? one more toxic than the other?

regards, mary

Mary, I don't believe closed-cell building foam is toxic at all. We shroud our houses with it. It's rigid, cheaper than the nivilty cones and comes in 4'x8' sheets. You could make a great wall to push the mounts into and it would be waterproof so you could spray it. Is there a down side? It only comes in pink and light blue (as far as I know). The white foam is comprised of small closed cell beads that are cemented together. It is fragile, breaks down easily, is easily damaged and probably not suitable. Hope all this helps your decision.
