Water pooling in bottom of grain spawn buckets?

Hi everyone, I am new to all of this and am trying my hand at oyster cultivation. I am making grain spawn using wheat in large 11litre (3 gallon) Plastic buckets which I PC, inoculate in a still air box and then leave to grow out . I Just transferred my first spawn onto bulk substrate and noticed that the mycelium had not grown all the way to the bottom of the bucket. This appears to be due to water pooling in the bottom 30mm of the bucket. I’m not sure if water is getting in during the pc or if my grain is too wet going in to pc. The rest of the bucket is a solid mycelium lump and looks great. The uncolonised wet grain doesn’t smell at all. Is this still ok to use? Any ideas on how to prevent this in the future? Thanks so much in advance.

OK. I just want to see if I understood you correctly. You put grain in a plastic 3 gallon bucket and pressure cooked it?

Yeah that’s right. I soaked for 12 hours. Then simmered for 15minutes, then steamed off and packed into white plastic bucket and put it in the pc. Wasn’t sure how long to do it for I have read 90 mins for grain jars but given the volume I’ve been doing 2 hours at 15 psi to be sure

So a filter patch and injection port of some sort? The water, sounds like the grains are too wet going in, if the filter patch is able to keep the water out. ? Maybe cover the patch while pcing.

I agree, too wet going in is likely. The larger size of spawn (or substrate for that matter) buckets you use, the more difficult it is to get the water content right so that it doesn't pool at the bottom.
I had the same issue when dialing in growing for 5 gallon buckets. Just use a bit less water each time until you get it right.
