Anybody use synthetic sponge for a casing layer?
    #4433780 - 07/21/05 04:19 PM (12 years, 2 months ago)

My workplace gets lots of sponge as packing material. I have searched and the only problem people say is that sponge is made or contains cellulose. I think synthetic sponge would be fine. The stuff I get is black and about 1/2" thick, there is thicker stuff too. Seems it would make a nice even layer. It comes in squares about 500x500mm. I could cram it into a jar to sterilize. Verm is pretty expensive where I live and this stuff is free.

Anybody ever use it, or see reasons it won't work?

Open cell foam will work, if you find some that will withstand being boiled for a short time.

Great, I am pretty sure mine is open cell. It holds a huge amount of water per weight of foam. I got a piece 6"x6"x1.5", when I saturate it no water escapes if it is held level flat, but if I tip it water freely pours out of it. TMC recommends 90% saturation level for casings, I fear this may be too much for this stuff, any thoughts?

I like the idea of a one piece casing as harvesting should be a breeze, no verm or soil sticking to the shrooms and the layer should be pretty much intact. However the top will be smooth and I know it is recommended that it is rough to increase the surface area. I could shred up the foam or else score the foam with a knife to roughen up the surface.
This stuff would be great for people trying res effect grows.

Try it out and be sure to let us know how it goes, as I have been interested in something like this as well.  It would be nice to not have vermy shrooms :smile: And it would be nice and level, no more worrying about if you eyeballed it wrong :p
