    I usually use the brick coir. But last time I used a bag of loose coir and got a bad trich infection b4 the 1st flush even!!! I've since heard the loose coir has trichoderma deliberately added to help with plant growth or something. So, as a note, stick with the brick coir blocks. The loose stuff is garbage for mycology.

    Actually, the bricks may have it added as well, so always read the packaging first before you buy...back in the day they never added it and when I was rocking I would buy a couple cases at a time.. I made up 20 tubs before I knew that the ingredients had changed...doh..lol

    I just bought 3 bricks. They're packaged for reptile bedding but it didn't say anything like trichoderma was added so I guess I'm good.

    Should be good then . When growing plants the trick is beneficial so they would advertise that on the package

    I think it says on the label.wicked cool for plants though. But trich will always be there, its close to impossible to remove it with only 1 soak of water.(boiling)
    one part of mycology is fighting off what plants normally want. We want a fully sterile substrate

    I don't sterilize, I pasterize my coir-verm-gypsum mix by dumping boiling water over it until it is at field capacity. Then I put the mix in a plastic tub and put it in a big pot of water and simmer, under boiling temps, around 160F for one hour. That does the trick. You never sterilize your substrate mixture! You want to leave some beneficial micro-organisms to keep a healthy balance and keep bad contams from growing on your substrate.

    Definitely not uncommon to pasteurize sub. While not REQUIRED for coir/verm a lot do it just in case. couple hours work for something that you have to cross your fingers and hope makes sense to just do it right. Youll see a post about live steam box which is another popular option on here for larger amounts of sub being done all at once. Not sure I would call ANY of this work, unless this is more than a hobby I guess. Ive been throwing a little of this and a little of that into my subs testing to see what makes a difference and at that point it is always good to pasteurize. But im a fan of consistency when experimenting.

    What's your water to coir ratio to get field capacity by just adding water to coir ?

    I just eyeball my field capacity coir verm. If there's too much added just drain it out or squeeze some liquid out. Coir verm doesn't have to be pasteurized but coir does sometimes harbor mold spores so it's best to do it to be safe. It sucks going thru all the hard work of making jars and colonizing them just to then spawn to an untreated substrate. The bucket tek works great for coir verm subs, but If i add worm castings I properly pasteurize it.

    I follow this same recipe and have only had issues with the field capacity. I also eyeball it as well. Usually it’s 10 cups water first pour, and second half pour is actually only about 7-8 cups. I’ve found if you have too much moisture, you will be green before a pin set. But if you do it right, it is the best and easiest.
