Sterilizing substrate
    #27043392 - 11/17/20 07:23 AM (3 years, 2 months ago)

Hello all. I am so grateful this forum exist. Please excuse me I am a newbie. I am about to inoculate my first grain bag. Bought a grain bag and pasteurized manure. I’ve seen people use coco coir for a casing in the mono tub. How do I sterilize loose coco coir in a bag. Ive see people poor boiling water on the coco coir in a bucket. Then squeeze  excess water out after. Is this procedure correct. Seems to me it might not offer enough heat for a long enough time. Maybe I shouldn’t use a casing

If it's your first grow, skip the coir.
it's another step you can fuck up even though it is quite forgiving.
I don't like coir for a casing either, the mycelium just colonizes it, which is what it shouldn't do.

the bucket teks are quite popular for bulk substrate.
They work very well and it's set and forget. to maintain the temperature for long enough, you can put bucket into bucket.
And wrap a sleeping bag around it.

Finally, buying pasteurized substrate is kind of tricky. pasteurizing sets back the 'bad' organisms but doesn't kill them entirely. it gives you a certain window of time in which your mycelium can take over the substrate with the help of the 'beneficial' organisms. however, you don't know when this sub was pasteurized nor when you'll eventually use it, a lot of time will have passed. the 'bad' organisms will have receovered and your time window will have decreased.


good luck with your grow.

If he did want to sterilize the bagged coir, how would he go about doing that?

look up bucket tek. mind you it's not sterilization. you just expose the brick of coir to high heat (boiled water) for a period of time. it's not pasteurization because it's too hot for this. the coir can take it because it doesn't mold easily.

to sterilize, you do it in the PC.
