Is WBS fairly contaminant resistant?




I'm not sure what would make any substrate particularly resistant; mushroom-friendly tends to mean mold-friendly. Used as spawn and properly sterilized, I've had maybe 1 jar out of 100 contaminate with bacteria.

I GOT A HUGE BAG THAT COULD POSSIBLY CAUSE A HERNIA FORM FRED MYER.

Only used it once.

Grain clumping with wbs has not been a issue with me ever.

Calcium Sulfate is essential, that's all I know. I don't entirely know the reasons for why it is, but multiple books I have and RR's vid both use it.

Calcium Sulfate is gypsum. It's not essential particularly for grain, though again, I'd ask RR in a PM how helpful it will be to an all-grain grow. I've never bothered to locate it, and never had any particular problems in dozens of coir, manure, and grain grows.

WBS: Anywhere. Look for the cheap stuff, as the sunflower seeds are the priciest and are conventionally picked out. A high milo content is preferable; I've seen all-milo jars colonize like wildfire.

Poo: Yes. Unfortunately store-bought manure is usually cow manure, composted and mixed with humus, all of which is bad. It has the consistency of mud making it infuriating to pasteurize, and needs a 50/50 combination with vermiculite to achieve the proper consistency.

This is why I'd go with coir, if you have a pet store nearby. I use pure hpoo harvested from stables...but I moved to coir after just three tries with straw/cpoo and verm/cpoo. There are 3 huge sacks of the stuff sitting in my stairwell, and I'll probably throw them out.

Coir huh? Hmmm It would seem I have to do some reading and step up my game. All I've done is whole wheat substrate w/ 50/50 case and BRF.

I can get WBS from a pet store as well could I not? One stop shopping is always a plus.

Does coir need to be pasteurized like poo?

Adagio, yes...but it's steam treated like I mentioned in the PM. You can get lazy. And indeed...I get my coir at a grow shop now, but I used to double up on the cheap. Full grow for under 20 bucks.

He also dug up some of my old (only tried a few times, and not well) posts on coir, during the Great Coir Casing Wars of spring this year. Oops! It works. Well. :smile:

the reason you dont want them to stick is because you want them to lose moisture on the surface of the kernel otherwise the parts that stick together will be too wet for mycelium

if the grain sticks together you wont get the proper moisture content evenly on the grain surface.. say if the grains stick together that mass of grain will be high in moisture inside the sticky mass so the mycelium wont be able to grow into that area since its too wet .. did I make that more clear ? sorry it was late for me last night .. that is one reason why you would want to use gypsum
do you have to have gypsum ? no but it would be a good idea if you wanted to get the best results possible .. thats why people use it ..
