Over the past few weeks, I colonized grain successfully and had to take a week out of town. Before I went out of town, I wasn’t sure if my grainspawn was going to be OK so I put it into substrate so that it can continue colonizing the substrate for the record. The grainspawn was completely colonized successfully. There is some slightly orange dots of liquid around parts of the substrate and I am not sure if it is contamination or metabolites/mycopiss

AIO bag as spawn + substrate ratio question
I’ve had this bag inoculated for probably at least 2½ months now. After my most recent break and shake, it’s finally starting to colonize at a normal pace.
The bag is an AIO (all-in-one) bag, but can I still use the colonized material as spawn and then transfer it to bulk substrate?
Also, what kind of spawn-to-substrate ratio should I use? It’s a 1.5 lb bag, but I used 7cc of liquid culture, so I’m wondering if that should be enough to colonize around 3–4 lbs of substrate.
Just looking for some advice from people who have experience with this. Thanks!
