Burleyman Posted November 13, 2014 Does anyone know the difference in benefits between diatomaceous earth and gypsum? Share this post Link to post Share on other sites
superdan Posted November 13, 2014 diatomaceous earth is primary silica based, gypsum is more of calcium based, Share this post Link to post Share on other sites
Burleyman Posted November 13, 2014 Yeah i know thats the case.. But the benefits/outcomes of using either one or the other with substrate to colonise? Share this post Link to post Share on other sites
Massner Posted November 13, 2014 The Diatomaceous Earth is used in grain to keep weaves and shit out of it, it is super tiny particles that are sharp and cut any really small organisms and it kills the fuckers. It is used instead of fungicides. Gypsum is used as an additive to get bigger yields and bigger mushrooms. Use to much gypsum and your substrate will go as hard as concrete - go easy on it. Two totally different animals, DE is used for growing pot as well to fuck up pests instead of using miteicieds which keeps it organic if you are going for organic buds.

Massner Posted November 13, 2014 I should have added the DE is added to the grain before you buy it so grain can be stored, my lat post is a bit fucked up. Does that make sense? 1 Share this post Link to post Share on other sites
Burleyman Posted November 13, 2014 Yeah i use it on all my veggies to keep away slugs and snails... barriers around all my plants and veggies!! amazing stuff.. Along with copper wire too so pretty much to sum it up... diatomaceous earth just keeps bugs out of your colonizing jars yeah?Gypsum and DE have no similarities in purpose to each other in this regard?

Nah the DE keeps weasels and shit out of the grain when in storage before you buy it, if it was not in there wheavils and other bugs would eat it and fuck it. Once you put the grain in the jars the preasure cooker then kills any spores such as mould and it is sterile so nothing will grow in it. You then add mushroom spores, Liquid culture or whatever you are useing and off it goes and colonises the jar. Share this post Link to post Share on other sites
migraineur Posted November 13, 2014 To quote RR "Gypsum is pH neutral while supplying calcium and sulfur, both of which are essential minerals the mycelium uses. It's not just about clumping grains either. You'll grow bigger and nicer mushrooms with gypsum added to bulk substrates than without." 1 Share this post Link to post Share on other sites
