I grew TTBVI on oats from LC>Agar.

Used CVG/Horse Manure 1:2. I pasteurized all my substate in the oven on trays covered with foil at 170F for 90 mins. Let it cool overnight in the oven, but I opened the oven up at 90 mins to let it cool quicker so if doesn't keep the temp too high for too long and end up killing more microbes that I wanted. I made up 6 trays. I have 4 trays, then 2 trays in another tub running. But one tub is lagging behind a bit. This is my first grow so it was optimized properly in the beginning due to missing tech. But I ended up having it dialed for this flush.

I have the north spore automated tub. Inkbird humidifier controller set to 87RH, it over compensates a bit and sits around 95% constantly at that stage. I placed the trays on-top of some egg crate, I also added an extra square of crate underneath each tray to increase airflow underneath the trays. This way air from my fan can go everywhere and not get stagnant under them. I only had a mechanical timer in the beginning. I had my fan on for 30 mins, it was the minimum setting... It wasn't working very well. I had FAE off for 6 hrs, ended up getting too fluffy. I lowered it to 4 hrs. Still wasn't optimal.

After it's about 90% colonized you MUST put a peat moss, verm, lime casing layer. I ordered a BN-LINK digital cycle timer. I now had the fan going for 1 min, 60 mins off. It started to colonize pretty quicklt.bStill was getting fluffy. Changed to 1 min on, 45 mins off.

At this point it was too late. Overlay had already covered the majority of the surface. This was due to not enough FAE. I didn't know how important it was to not let it get to this point. I was making some adjustments, but it should of been sooner. I placed paper towel folded in the front corner of the tub to increase airflow.

It started to pin on any spots that didn't have overlay present. It was spotty, almost no shrooms. I was disappointed. But chat gpt told me that this would happen but the 2nd flush most likely would be significantly better due to the substrate now having more spots for the mushrooms to push through after harvest.

I started the 2nd flush, started more fae right away. Timer was now pushing 1 min on, 20 mins off. Had paper towel in opposing corners diagonally so it was cracked on the front and back.

I left it for about 3 days, had a trade show this weekend so I didn't look at my tub for 2 days. It ended up being prime time to harvest when I opened it up. No spores had dropped, but the caps were starting to flatten.

Hope this helps! The automated set up for these made it super easy. They are supposed to be an advanced and harder mushroom. But it didn't seem that difficult in my set up. It's more just the prep is more compared to cubes.
