Shiitake on rice hulls progress

Hi guys and gals. A few month ago I ran some Shiitake 75 mycelium through some rice hulls in a test tube and found that the high lignin content of the rice hulls were desirable for the strain. 2 months ago I made up around ten bags composed of a mixture of rice hulls and rice bran. The mix was 90% hulls, 10%rice bran. They were all inoculated with one quart each of wheat grain spawn. They were completely colonized in 2 weeks and then incubated for the remaining of the 2 month span. At 1.5 months the bags were around 70% browned (estimate). At the 2 month mark due to a move and shifting of the bags during transport all the bags went into fruiting. I then decided to birth the blocks and fruit them. All the blocks were stripped, mushy fruit bodies cut off, and placed outside in the shade to sit for a week. After a week I started dunking them one each day for 24 hours of dunk time in chlorine-free water. Each block was slapped silly, placed into a sterlite container and at two days each, they started fruiting again. Here are some pictorial results.
Due to the inconsistent progress from the move and early fruitings I believe I lost out on production during the fruiting cycle I initiated after the bags fruited in-vitro. The mushrooms in the bag were quite large and a lot of energy was wasted. The first thee pics are from my new cycle of bags and I am sure in 1.5 months time you will see much more and larger fruiting bodies on the blocks. Wish me luck.! At 10 bucks a 50lb compressed bale of rice hulls and 8-10bucks a 50 lb bag of rice bran and not having to hunt down sawdust. That's pretty good.
I have one other strain of mine that will colonize the rice hulls at a much faster rate than the shiitake 75. I also am starting some trial runs with it. It is my #104 strain.
Edit : FYI -These are medium blocks by the way
2 days
 1 week  2weeks
Elongated stems due to lack of fresh air from little holes in the container.
 Better fruiting container. The perlite on top is from inverting the block at once a day intervals until the fruiting commences.

Mycelio said: Hi Lipa,
intersting, rice hulls should be pretty similar to rice straw. Am I right, estimating your bags contain ca. 20% grain spawn? Please keep us updated about the BE once you got an undisturbed first flush.
