Great for easy inoculation and growth.
love the new style / cap filter / jar size. it took hold of spores VERY quickly! highly recommend! jb.
Read the other reviews and was very excited about these jars. But I'm at about 80% colonization and it seems that the jars have stalled. They've been in the inoculation chamber for 26 days and I havnt seen much change in them in about 10 days. My 5 grain spawn bags are actually starting to catch up and those were inoculated a week after these. Pretty disappointed in the results (time-wise) so far. Don't think I will be ordering these again.
After a dozen or so orders with Midwest they have become my go to. Super fast shipping and the quality and performance of their products are 2nd to none. These new jars have a smidge more room in them to shake things up . Less than 2 weeks and these are basically fully colonized with liquid culture .
I've never had any issues with there products. I have used other companies. It not near that quality. One company sent grain bags that where 6 month old. They left the date sticker on them. This is the best company and there prices are fair.
