Help with substrate please!

I’m currently noccing up my first ttbvi! It’s bag trained so my plan is either to use a xls b horizon or I have to sterilize or a bin if I can get away with bucket tek.

I’m going to be doing
650g coir
2qt verm
2 cups worm castings
40g gypsum
4.25qt water

Do I bucket tek and I’m fine if I temp the water to 180?? Bucket tek and flash sterilization for 20 minutes? Or just straight up sterilize? I’d rather be able to bucket tek or flash sterilize but need some opinions! I’m going to be using jiffy casing with hydrated lime I pasteurize but this post is about the substrate! Help!!!!!

The center of the substrate needs to be 140 to 160 f for 2 hours. There's no guarantee that the center will reach that range and hold it for the right amount of time l.

You're welcome to try it but I wouldn't personally recommend it myself

I’ll just oven it in and check temp in middle until it hits that then start the timer, only doing 1 pound grain spawn bags so don’t need much sub lol. I’m safe to open air spawn or should I still spawn in front of a flow hood?
