A few weeks ago I decided to try making some oat spawn since people have been raving about it and it's so cheap.
Initially it looked less dense than what I'm used to (have usually been a WBS or rye guy) and as the colonization spread I had the opinion that it was contaminated with something that was not killing it but perhaps slowing it down or making it less dense.
I went back to the drawing board and created a whole new sterile liquid culture, and this time I am testing out one jar with WBS and another with oats. This is the SAME exact LC. Both jars inoculated with the same syringe even.
It's been 3 days since inoculation and the WBS mycelium looks a lot more dense and "happy". The oats have wispy beginnings of growth. Is this normal? Does the straw-like husk outer layer of the oat grains make the mycelium behave differently?
