An experiment with extra BRF...

Hey all. I'm doing my first experiment, and I happened to have too much BRF and too little time! So instead of waiting for the jars to free up, I decided to improvise...
I made PF substrate mix, many jars' worth, and now have it baking in the oven. I've already read that this is a bad idea, as it dehydrates the mix, but I taped around the lid of the container then wrapped it in aluminum foil. It's baking as we speak, for another 90 minutes.
I'm thinking of using the PF substrate for a casing, spawned by a cake or two. It'll go something like this:
1/2 to 1 inch of moist verm at the bottom of the tub the PF substrate, which I expect to fill 1 inch of the tub, +/- 1/4 inch. Then what on top? I'm thinking 50/50 verm and peat moss. Should this be moist or dry? What water to casing ratio is appropriate at this layer?

I don't think I've ever seen anyone successfully sterilize by way of the oven. It's been tried many times, many different ways. You will run into the same problems as the rest. If you have an oven, there's a good chance you have a stove top, correct? You should boil your pf tek jars. When you get your jars fully colonized, I would not do what your plan described. Instead, since you seem interested in spawning, go ahead and break your cakes into the smallest pieces you can make and mix it with coir/vermiculite or even just vermiculite works. You need to make sure and properly pasteurize the material you decide to spawn to. The water ratio you want to achieve, and become quite familiar with, is called field capacity. Hope that helps.

Ah, the 3,000th failed oven tek coming up. It seems to be a rite of passage with new growers to think they don't need a pressure cooker, and then set out to prove it. RR

I don't have any jars left, so I don't get that option. I'm not doing this because I think it's better than the established method!

Then I shall live and learn 
My goal here is not to use the oven, it's to make a casing with this excess PF substrate. If anyone has suggestions, I am listening.

Thanks for the helpful post! Why can't I add more sterilized PF mix to the crumbled cakes? Would doing that be harmful, or is it a matter of the reward:effort ratio not being high enough?

I have never personally tried using brown rice flour as a bulk substrate or additive, so I can't say for sure it won't work. However, most people would agree that it isn't a good idea. It would probably contaminate before it fully colonizes, and I can't imagine it would be very easy to work with when spawning. Horse manure, coir, straw, vermiculite are all very good for bulk substrate material. Not because they are highly nutritious like brf, but because of their water retention properties.

That makes sense. I don't know about horse manure in my apartment, so I'll look into coir and verm. Thanks for being helpful:)

I'm actually quite interested in the results of this. Assuming you don't get contaminations from the lack of PC, I don't think i've heard of PF mix being used for casing. Interesting.

I've thought about doing this as well too. From what I've read brf is pretty nutritious. As long as you don't get contams I don't see how wrong it can be?
