The trick to successful bag grows is having a lot of air circulation in the room. I think the fruits have a tendency to get a little bigger too cuz the high co2 levels. The filter patch don’t got nothing on a hole stuffed with poly as far as fae goes though.
Nice work man!
I dunno, personally, I'd see if the coir is still moist and try to get the gt growing. Then make up a little more coir to see if the aa will grow.
Got nothing to loose. Maybe grab some for some g2g or agar if your equiped.
If your cake smells that bad... Its got contams. Throw it away and start over. The biggest thing you can learn from all of this is to be steril... The cubes know what to do when its steril.
If you are growing bulk, its best to have a substrate PH that is slightly high. But steril. That's when it matters. Beyond that, the agar will be fine with no other additives. Cakes, there are a lot of recipes that others have had great success with, same goes with bulk substrate.
Just my 2 cents
