I was thinking of using those clear plastic tubs I have in the pictures somewhere above.
Hello Tabby :D Glad to see your progress thus far. Do you know that variety of mushroom is in the posted picture?
I would recommend the rotisserie tek and a bulk substraight. If you are looking to make bulk substraight then 50:50 coir:verm is a great route. This bulk can be made in a bukket or oven.
I do variations of the rotisserie tek with great results, One of my rotisseries made it as a contender for picture of the month this month! When doing a rotisserie tek a 1:1 ratio of bulk spawn to grain is best because of your time constraint ;), This way spawn run will go a little bit faster. Seeing you have a good amount of grain spawn you can get a few trays done this way.
For rotisserie tek, one doesn't need a rotisserie container, a miniature dub-tub made from plastic containers works fine. You can also get those plastic quart deli containers as a fruiting chamber.
After thinking through it you should be able to get nice and fun cultivation time with any container type. But I still would recomend to do multiple trays or containers just to be safe :)
PS. If you are not meat eater perhaps you can do a dub tub with plastic containers?
If anyone reading knows ways to purchase rotessorie containers without included chicken lmk
Whenever I spawn, should I cover and let incubate or just leave it like it is when I spawn and wait for fruits?
