jumpstarting stalled horse(poo)

This happens a lot: A tray of horsepoo with crumbled pf cakes as spawn colonizes nicely for a while then stops or slows down before completing. I've tried different things but had little success. I think air exchange is the problem but I don't know.

Hmmm sounds like it might be a moisture problem actually. Stalled growth is often due to overdrying of the cakes and loss of moisture. How dry are the cakes before you add them to your casing, perhaps it would help if you dunked the cakes before your crumbled them???

That's an angle I havn't explored. Thanks. I assumed I was too moist on some. The incubator was literally soaking them with condensation and mycopiss was accumulating too. The dunking sounds good though. I'll try it. I'm gonna put more holes for air in the trays too-- using tyvek on the bottom. I use an aquarium heater inside a big jar filled with h2o in the corner of a rubbermaid container for incubating now. Before I was filling the container with water and putting a long aquarium heater in that and then actually immersing trays alongside. It was messy but I had about 25 to 45 percent success.

hmm if it turns light brown after some nice white, its normally to wet. i wouldnt have my incubator have high humidity, just cover with lid or foil over your tray poke some holes. and keep it at 85 should be good, make sure your poo is fieldf capacity hand squueze it for success

yes I have experienced the same thing. Growth rate is excellent and then it seems to slow way down.

And then contams get in and it's all a waste. The trays are rubbermaid clear plastic with outside covered in tin foil to block light. Maybe there's not enough air exchange and heat exchange is uneven through the substrate. Also, as I said, the substrate is usually a bit wet. I've been fighting some cobweb on a few of them. It doesn't look good overall, yet the mycelium looks healthy still where it did colonize. One last thought, maybe some light is getting by the containers and causing these failures.

this is usually a sign of over heating . try lowing incubation temp to 80-82 F .because decomposing horse poo generates a little heat .

Thanks for the input. I think that is a factor too. Lowered temps a bit -as much as possible -heat is probably pretty uneven in the containers. Another thing -I think the mixture of the substrate could be fluffier to allow more air. The average container is about 5-7 lbs and the poo is pretty dense.

what i've done is break up the mycelium removing any uncolonized portions. I did this about three days ago so it's too early to tell about results. What I do to fluff up my cow poo is add buffered peat moss. I also had a heat lamp in the closet which I have now removed. Up until this point the internal temperature was around 95 degrees. I think also that I am just getting a little impatient.

That's interesting. The tray survives being "broke up". Looking at healthy white rhizomorphic growth next to dead horsepoo --it's tempting to break up and hope that jumpstarts the tray. Ya know I think it's worth it. There's nothing to lose at this point.
