Great product

I ordered several fruiting blocks and all but one fruited wonderfully. I called about the one that didn't produce and they promptly sent another no questions asked. Highly recommend.

Best Grow Bags Available

I've tested grow bags from North Spore and all the top rated brands on Amazon - nothing can compare to these grow bags! The size, health, and yield I got from my three SWM grow kits are absolutely amazing. I will be buying exclusively from SWM going forward.

Great Results, Totally Glad I Found Southwest Mushrooms!

After lousy experiences with North Spore and others (contaminated spawn/growkits), I tried Southwest — and I’m sticking with them. Decided to try a Lion’s Mane grow kit, and I’m beyond satisfied. Whatever strain it is, it’s yielding dense, white, tasty fruiting bodies as hoped, and better than any others I’ve tried to grow. Might try from scratch using spores in future, but waiting for a second flush to come in and totally happy.

Perfect delivery

Really excited for this first purchase from SW. Ordered two Shiitake based on watching their production on YouTube. These blocks arrived in perfect condition, not fully matured, but I’m not disappointed. I love watching the evolution of fungi. The anticipation of what’s to come should be worth it! Look forward to seeing more from you Michael.
