I use to prepare grain-spawn in those microwavable brown rice bags. Just inject LC (without microwaving!!) and cut a little hole for AE in one corner and fill it with polyfill (all in glove box). Then gently squeeze bag to loosen up the rice a bit. Incubate…done…moisture content of the rice grains seems to bee sufficient.
This particular bag has been inoculated with king-oyster LC on the 13/10 and that is what goes onto bulk.
As with everything there might be some drawbacks as price (around $3 per bag), hard to track myc grow (apart from the bottom-window which is clear plastic), no shaking therefore probably slowed growth…but if you are not too much in a hurry, only need small amounts of spawn and work sterile I found it to be the method with least hassle.
