Great genetics quality grain spawn

I recently used the grain spawn I ordered and was very impressed by the quality and quantity of mushrooms I was able to harvest. I'm looking forward to purchasing again soon. Thank you so much Mike for calling me personally to ensure I was getting what I need to start up my farm, I really appreciate that outstanding customer service, you truly are passionate about what you're doing. One love man

Great, and efficient spawn

Nothing has taken off quite as fast as this has, price is a bit high, but for the quality product it's a must buy for at home mushrooms growers. Black Pearls took off, and produced a giant pin set within a week of being in the grow room, snow oyster, blue oyster, and pink oyster I've yet to put into grow bags, but I'm excited for the results.

Great products

Ordered two grow kits from Southwest and both were healthy and bags were sealed very well with great healthy mycelium. The grow kit had very good instructions that come with them. Very happy
