Afternoon, family. I wanted to make this post for people having trouble getting more than a third flush.
So, I grow in pre-made AIO bags. Mostly because they're in my budget for now. After my first flush i usually dunk my cakes inside the bags for 4 hours maybe. After harvesting my first and third flush the block became beat and bruised. Spores dropped all over, and stroma (i think?) was starting to show. There would be a lot of aborted and stressed out bruised pins that just would not do anything no matter what I did.
Naturally my intuition told me to flip the cake after rehydrating for the fourth time, and let the matted layer of mycelium lay face down. I am now starting to see more primordia forming. Not on the surface, but on the sides of the block. If you have not tried that, I recommend that you do if you're really having trouble. I don't have pictures to show but I am starting to see more growth just a couple days after dunking. I almost tossed the mf, but so glad I didn't haha. I've pulled more than an O dry just off of one AIO bag.
Hopefully someone can benefit from this. I don't really see it talked about anywhere.
