Just spawned the last 6 jars (I have 12 490ml jars in total)
This grow I have done 2 lots of 6 jars, inoculated a week after each other.
First I break up the cakes in a large freezer bag. Most people just break it up and mix direct in the tub, but I find this easier to get a thorough mix
Add the coco + vermiculite + gypsum mix into the bag at a 1:1 ratio (1800ml to 2000(ish)ml)
This sub I made with 650g coir brick, 2L vermiculite, 1/4 cup of gypsum, and 4L water. Ended up making about 10L or so of sub, so will need to adjust that in future.
Lining the bag is by far the hardest bit… My tubs are small and its fiddly. I may buy a roll of polythene and use that instead of bin liners.
Add the mixed spawn
Top off with a layer of coco + mist.
