30 out of 36 colonized, I think the spores in the syringe were old and just failed to colonize. No contams, moved onto bulk substrate after 4 weeks. Going to try the jars that failed to colonize again and hope they take this time
I've used MGK half a dozen times now and they're definitely the gold standard for RBF jars. Took advantage of their black Friday sale n saved 10 bucks. Kinda wish they had some kinda send back program so I didn't have to recycle the jars after. Great customer service, had an issue with contamination and they sent a discount code for the next set n I've had two successful grows since then. I'll remain a return customer for the foreseeable future. Only takes a few days to receive and if you follow the instructions you're bound to see the fruits of your labor. The jars are also perfect for dunking. After washing them just fill them halfway with water n use two 3x3 Legos to keep the cake submerged, has worked wonders for rehydration.
Great value and even better product, these jars are reliable and always work. I am very satisfied and will continue to purchase
Received order approx 5 days after shipped. Fresh sterile product 2nd order no contaminants Great yield from 1st order consider great quality
This yr i bought the 12 ½ pint jars, they're different than a yr ago but ive gotten extremely fast growth. All rhyzomorphic and just after 5 days my jars are overdue in mycelium. Best price and best jars I've ever used.
