It's on day 5 now and the 1/4 inch pseudo-casing layer is almost colonized. I'll be moving it to fruit mush sooner than expected since I am seeing some healthy primordia develop now.
I can't rave enough about Denver Spore Company genetics enough!
A touch more than 1:2 by volume. I added vermiculite this round to help mitigate moisture loss since Colorado has a really dry climate.
I am going to play around with the spawn/substrate ratios over the next few grows to see what works best, for sure. Last grow, I did a few experiments around how much to compress the spawn/substrate when I did the S2B. (Moderate compression had a huge impact in reducing side pins that I think improved yield.)
Nice, that seems like a good sweet spot with the ratio. I do somewhere between 1:1 and 1:2 myself, (usually closer to 1:1) but sometimes I wonder if that's a bit much. I've found compacting/compressing everything will stop side pins through the 1st flush, but my cakes always shrink up after 1F and I inevitably get the side pins then haha.
Also I hadn't realized you're the same dude with the sprouts in your tub!! Is this the one they popped up in?
