New to the thread, pretty experienced in diy mycology projects. Havent gone far through the thread, but the pics on this last page have me wanting to ask some questions and give some advice.
First off i notice you have foil on top of your grain jars and the ones not foiled have no ventilation for gas exchange. Gas exchange for growing mycelium is important. Not having ventilation will slow growth and can cause the mycelium to stall growth, giving any contaminates a chance to take hold. Look into making breathable lids with inoculation ports. You can do it cheap by using tyvek and RTV silicone, or you can get wheel filters and inoculation ports online to make it more professional looking. Both work well. Keep foil off so they can breathe.
Another thing is it looks like youre keeping them in a mini fridge. In my experience light is very beneficial to growing mycelium, some people will argue this point, but ive found it to be true. I leave my jars sitting near a window so they can catch some light.
In the pic of the tubs, is the big one your SGFC? Or is it your bulk tub? If its a SGFC, holes should be on all 6 sides, spaced 1 inch apart. If its a bulk tub (monotub), you should use holes 1 1/2" in diameter. 1 on each side a little under the handles, and 2 on each large side just a hair over your expected substrate level. Look up monotubs for more info.
Sorry if anything I said was already stated on another page, i havent read that far into this thread. Best of luck!
