## Questions & Answers

**Q: Is this suitable enough to use as the actual grow medium?  Would I still need the substrate (rye berry, etc)**
A: You will need to combine this with colonized grain spawn. It will not support colonization on its own.

**Q: What types of mushrooms grow best with this mix?**
A: Dung loving varieties

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

**Q: How do I use this with a 32oz jar of colonized substrate?**
A: Boil water.... Drop all that stuff into a bucket or large pot an stir it up, add the heated water, seal it (i used plastic wrap ....but if you have a bucket with a lid use that) let sit for hours till its cool or at leased a little warm // ....now your ready to break out the monotub etc. Youtube 'Monotub and substrate'

P.s. dont use as much water as this pack says....mine had Way to much water, had to squeeze it out by hand, still to much....
