Great all around and good customer care no complaints and will buy from them again.
Best spawn/sub jars I've worked with so far. Colonizes VERY easily if inoculated correctly. Never had any issues with them and out the dozens I've used in the past the only ones I lost to contam were due to improper sanitization on my end.
This product, like any I've ever purchased from MGK arived quickly and without incident. This high quality, regent grade chem is a must have for any grow op.
Having ordered these several times, I can say that they work and are consistent in being top quality.
1 Substarte jar was broken 5 still intact. What do I do? I live in Alaska
