No I didn't measure any of it, a total crap shoot.
I'd guess I added about 30L of water to get to the desired 65% hydration so about 45-50kg of substrate would be a guess.
The grain spawn was a big bag as it was when I changed my hydration method (why I think it colonised so quickly). I'd guess it was about 3-3.5kg.
I'll weigh it all in a week or so when I check on it & let you know. It's currently buried under other storage boxes 😆
That’s big!
Yeah - like I said total crap shoot, a gamble.
I'm betting that the low nutrient value of the substrate, the aggressive fungi & the little bit of wood ash I added, will allow the substrate to colonize without contamination.
I didn't know what else to do with the big bag of grain other than inoculate a pile of wood chips.
I figured I should try the mushrooms before letting them loose in the garden.
I also used some of the grain to inoculate a bag of straight sterilized sawdust. I will probably add 30% wheat bran to the sawdust spawn bags in the future. Sawdust spawn bags seem less susceptible to contamination in the substrate but provide less yields.
Yeah I got too excited.
It's closer to 25kg of medium & 3kg of grain spawn.
I forgot about all the water that I poured out when I drained it too.
