The 3-Pack Premium Quick-Colonizing 5-grain Jar (32oz). Arrived Super fast and undamaged. I Innoculated, the jar and within 3 days have strong mycelium growth. will definitley buy more jars.

Originally tried the half pint jars and had a lot of contam. 10 days in on these bad boys, everything looks great, and about 30% colonized. Highly recommend.

I’ve used over a dozen of these now with 100% success!

I’m addicted to ordering these!! They deliver the Best results every time and they are of high quality... best part is you can re use the jars. If you haven’t yet... check out the liquid culture kit it pairs very nicely with these!!! Much love ??

Last year I purchased jars and bags and nothing germinate with spores from premium spores. $100 wasted. Switched to Mushrooms.com and 100% germination. Please stop recommending premium spores it makes your product underperforme its potential.
