Hey Luca,

try putting vermiculite or something that can soak up moisture in the grain/substrate bag if your having problems with too much humidity and liquids pooling at the floor.

You can also try less hydration of the grain (cook it on the dry side) and let the extra liquid from the LC balance it out…

I’d test the LC’s before using them on a big batch, I’ve had to throw away lots of grain because I got confident with a Liquid inoculation, never hurts to make sure…

also, I wouldn’t lc to the pasteurization bath. actually now that I think of it, inoculating with LI or LC will never be as good as inoculating with grains (specially if your using straw). I recommend growing out the culture in agar> agar to lc> lc to grains > grains to substrate… much easier and each grain represents a seed of mycelium which will up your chances

hope that helps

I understand where your coming from and your right there are probably a lot of people just sourcing already made grain spawn for their projects. I still believe that it’s not rocket science and not too complicated given you develop a good sterile technique.

From a cost point of view, how much is a lb of mushroom grain spawn for you guys?

Where I live sourcing readily made spawn is very hard so I’ve gone down the route of building my own little lab/sterile room where I can experiment freely and safely. There’s always the future possibility of distributing grain spawn to other people wanting to get into mushroom growing as well. Another added benefit is that you can experiment with many different species such as shiitake, king oysters, medicinals, etc.
