I use 5x4 bags (next size down from 8x5) with a .2 micron filter for grain spawn. I assume you are making grain bags from the filter size you have chosen. If you are planning on making substrate bags go with .5 micron.
If you need any help preparing your bags I can help you out.
My immediate plan was to take grain jars and inoculate substrate in the bags in front of a flow hood and impact seal them, then just cut the bags down when it's time to case and fruit. Now that I have clean cultures on agar going (still new to me) I had considered doing a Blue Helix LC to sub also.
Is .2 just not enough GE for colonizing a bulk substrate? My goals aren't to produce tons of yield, I'm just experimenting with my first selected clones and some Ps. Semperviva/Hoogshagenii. I'd like to start working to develop/improve some cultures.
The bags I have in the cart now are described:
All in One Mushroom Grow Bag/Farm-Mushroom Spawn/Sealable Spawn/Myco Bags,Large Size 8" X 5" X 19",0.2 Micron Filter, 3 Mil Polypropylene,for Substrate Autoclavable (50)
