Not sure if the myc shows up with my crap camera , but if you look REAL close ...
I looked real close and got freaked out by the faces on your fruit bowl. But yes, the myc. showed up nicely too. :D
In all seriousness, I think you might have come up with something big here. For one thing, the compression you use goes against the typical advice of not packing things down too tight, but the pictures of your results speak for themselves. Not only that, but the pucks (I'd stick with that name, it's catchy) are more contamination resistant and appear to be producing larger fruits than traditional cakes of the same size. Something's going on here that goes against the grain of conventional growing advice, and that's worth exploring further (to say the least). Blending up the cardboard and other stuff with Karo or potato water and still not having your pucks contaminate while colonizing in open air would not be the result I'd have expected.
No PC required, no HEPA filter, no stack of quart jars for spawn... I can see this becoming really popular. :bow:
My next thought was that I'd like to try making big blocks with a trash compactor. :amazed:
Or a piece of 4" PVC pipe; jam the substrate into a several-foot long section until it's packed tight, then push it out the end like a sausage and slice off pucks as it comes out or maybe even fruit the whole thing as a log.
I do have to admit that putting so much compression on a glass jar makes me a little nervous. I've had jars break in my hands before but I luckily wasn't injured (well, it wasn't really luck, it was how I was holding them and the thick leather gloves I was wearing).
Great write up, and I think we're going to see this technique take off exponentially as people realize it's potential.
