[Tastebridge] Coffee grounds for mushrooms

If we go with wet grounds, we must adjust the moisture with vermiculite, which I have several cubic feet.  Even if we must use 50% vermiculite per volume, I think we'll be fine if we supplement with the Spawn Mate II, which I will bring. I will also bring bags, hydrogen peroxide, digital scales, a syringe, oyster spawn, and sealer.

Hi mushroom growers,

I committed to delivering 10-20 pounds of dried, used coffee grounds tonight. Unfortunately, the weather was unsuitable for drying the grounds this week on the days that I would have been able to dry them. The weather outlook looks good for this week but unfortunately I won't be able to have them for tonight. I could still try to obtain some grounds today but I won't be able to dry them. I'm not sure if it makes sense for me to bring more wet grounds tonight since someone else has already committed to bring them but I'm happy to try to obtain them if someone thinks they'd be useful.
