getting big chunks of mycellium but no pins

I get chunks of mycelium and even some mycellium dust but never pins. When I take it out if the incubator, it dies back. When I leave it in the incubator it dies back then grows orange mold. Any advice?

This is the first time I have tried it with individual bags. I was previously using laundry baskets inside large garbage bags.

I would think that it would pin when it thought it had run out of food. This could also be seasonal, as it would like to display its spores at a time when they could grow on any other substrates that would likely be around at that time. I have found that if I remove it just before it pins, it can keep growing, but I would need to add more substrate.

So your theory, assuming the "season" is right (i am growing inside) is that the substrrate is not yet fully exhausted of nutrients?

Yes.

Short and to the point. Thanks, John!
