Surfin' Spores CVG Mushroom Substrate | Dry Bulk Substrate for Mushroom Growing | Makes 10 lbs of Pasteurized Substrate | Perfect for Monotub Grows | Coco Coir, Vermiculite, Gypsum

Q: Is this suitable enough to use as the actual grow medium? Would I still need the substrate (rye berry, etc)

You will need to combine this with colonized grain spawn. It will not support colonization on its own.

Q: What would the mixing measurements for a small batch?.. Say ..only needing a lb or 2 at a time..

I read that you can make a full batch and leave it for up to 6 months before using it all, so if you're going to be growing more batches in the near future, I'd probably just make the whole thing. Otherwise, you can measure out 1/5 of each of the three ingredients. The gypsum is the hardest to measure, but nothing needs to be exact, so I wouldn't worry too much. The big thing is to start with much less water than they say, like 12-14 cups. Now, they might be telling you that so you have enough boiling water to more thoroughly pasteurize the substrate, but if you use that much, you'll have to use a colander and/or manual squeezing and draining to get rid of the excess moisture. If you don't know what "Field Capacity" means, you need to do more research!
