Backyard Aquaponics
A place to discuss aquaponics

Long time reader, first time poster. Normally I find my answers on this forum but for this I couldn't seem to find someone who'd already asked, so finally needed to register.

Home Depot sells this extruded polystyrene sheet (XPS) called "Owens Corning Foamular" which seems to be a pink version of Dow's Blue Board. Lowes has a better deal on the Dow brand so I'll probably go with that, but I was just curious. It seems to be the exact same product as the Dow Plastic stuff except for color and Price.

Thanks everyone for all the excellent information on this forum.

I'm fairly new to aquaponics myself and the research I did comparing Dows blue board to Ownes pink board they appeared to be extremely similar - so much so my floating raft has the Ownes pink board mostly because Home Depot had a better deal then Lowe's did. If nothing else I can say from their growth that my kale, chard and lettuce don't mind the pink board.

Sadly, I didn't save the searches for the technical data but its out there if you feel the need to dig it up.
