    Hi all, first post. So I recently procured some Burma syringes from DocsDankSeeds. 40 cc total (wanted to make sure I have enough to fuck up).
    After some initial research I’ve decided I’m going to spawn in either a jar or a sterilized grain bag and then fruit in a monotub. I’ve seen Shroom supply offer pre sterilized grain bags, and I’m wondering if anyone has used pre-sterilized bags/compost for bulk substrate and if so, did you just go straight for it or did you pasteurize to be safe?

    In theory, the sterilized bags look like an obvious choice. I wouldn’t need a PC, I wouldn’t need jars, I wouldn’t need to wash and hydrate the grain.
    But in practice, I see nearly everyone using some variant of some jar tek. Anyone have a bit more insight into this?

    If you don't have a pressure cooker and want to do grain then this would be your only choice.

    I mean I can always buy one, I’m really wondering if the sterilized grain bags are actually sterile. Finances aren’t the issue, I just wanna know what’s easiest for a noob and if they actually can be trusted to be sterile and not contam

    I see plenty of comments on people having contam issues on the kits.

    Personally I'd rather have my hands on all aspects of things. And they charge way too much for something that is easy enough to do at home.

    Do you think it would be wise to bag them up in vac sealed bag (so like double bagged) and drop them in some boiling water for like 30 minutes then wait for it to cool down to inoculate to be safe?

    Not sure what you are referring to by them. Are you talking about reboiling presteralized grains?

    If so id say boiling for 30 min wouldn't achieve much. When prepping a grain bag most pressure cook for 2.5+ hours and pressure cooking goes to a much higher temp than boiling does.

    I feel like if you are planning to try to retreat grains you might as well prep them yourself in the first place.

    I went with some mycohaus grain bags. Next time I’ll probably just do a jar tek but I’m seeing mycelium developing today no contams in sight yet so hopefully things go smoothly. Inoculated on Saturday with some Burma spores Fromm DocsDankSeeds

    That's some powerful fast spores if you did it 4 days ago. I generally don't see on a petri for 10-14.

    Good luck.

    Hello I've used the sterilize Grain bags it is not necessary to sterilize them again. Used the grain bags a couple times like 8 times only had one which I thought could have been contaminated. Go for it just inoculate and see what happens just make sure everything on the outside is clean
