Casing with perlite and coco instead of vermiculite and coco
    #3043344 - 08/24/04 10:42 AM (12 years, 9 months ago)

Can I use perlite instead of vermiculite in a casing?
Thanks!

Im sure it would work but the point of using verm with coir is to increase water content. Pearlite is used for increasing drainiage and airation so your casing will dry out faster.

Yes, but it may not work as well. Perlite does not absorb and hold water, but wicks it (which is why it works good in the bottom of a fruiting chamber, to drag water up from the bottom and let it evaporate into the air).

The basic rule for casing is to use a non-nutritative (no nutrients, sterile) material, which perlite, cococoir, and verm all are. The accepted best 50/50 verm/coir mix likely works so well because it holds water (verm) and gives nice airy spaces for pins to pass up through easily (coir). So you just lose the 'holds water' part by using perlite - but who knows it might work fine. I don't know if anyone has tried it and has experience with it being better, worse, or indifferent.

Perlite will not work effectively at all forget it. Also coir is not sterile by any means it is made in an open air environment (large vats) coir needs to be sterilized. GL guys
