Once you've inoculated, wait until you actually see a white cloud in the substrate. Otherwise, if you then inoculate pre-maturely with the culture, you may be introducing wet rot into your system. Growing mushrooms has been an entire learning experience. I've yet to see many bloom, but I'll get there!

Easy to use, and it's working wonderfully.

With these big jars they worked at the same speed as the small jars and I got perfect liquid culture from using liquid spores again within 10 days all I can say is unbelievable I love it

The initial package came in quickly. The liquid culture looked cloudy, so I took two pictures and sent them into customer service for review. The young lady reviewed the pictures with me over the phone and indicated that it needed to be replaced. I received the new package within 2 days. I am really impressed by the customer service. Excellent product and excellent service.

The real deal took one day to see growth!
