Vermiculite pasteurization after opening
    #27306828 - 05/13/21 09:24 AM (3 years, 8 months ago)

So I'm aware verm is clean out of the bag.

Mine's been sitting outside open for a couple weeks.

Will it need a little bucket tek loving?

i usually just throw it in the bucket along with my coir before i throw boiling water on it, but honestly i don't think you'd even need to do that if you didn't want to. i totally get why you'd wanna pasteurize seeing as it was just chillin outside (i did the same thing) but i don't think it's necessary since verm is inert. like, the mold spores & shit already exist in your house in open air so i don't think it's fundamentally different than just having it open in your house somewhere. it's not like it's sterile when you scoop it out with & mix it into tubs with your hands or anything

If your bag has been sitting outside opened, it's filled with mold spores, more so than if the bag were in your house opened. I definitely wouldn't add something to a pasteurized bulk substrate that has a bunch of mold spores all over it

i guess i shoulda asked if you were spawning to coir or not. maybe to manure it would be sketchier, but i've had a bag of verm that got left outside for months & rained on, i just threw it in with the coir when i poured my boiling water onto it. i ended up adding a bit more just dry later & haven't noticed an increase in contamination. obviously no harm in throwing it in the oven/PC, but as long as your spawn is clean i honestly think you'd be ok unless it's been wide open the whole time & there's like bird shit in it or something lol. i'm assuming you at least had the top folded shut or something but i think what really causes contams is just unclean spawn if you're using coir/verm. but again, no harm in just throwing it in with the coir & boiling water (if that's how you roll- manure might be a different story idk)
