Mushroom substrate jars are a popular choice for many home growers because they have a lesser chance of becoming contaminated when compared to grow bags. Jars also colonize very fast, usually within 3 weeks. Each jar lid features a self-healing injection port and synthetic .22 micron gas exchange filter. All of our substrates jars are made-to-orderand shrink wrap each jar to lock in freshness.
Mushroom substrate bags areless expensive than jar substrates because they weight less than glass and arecheaper to ship . Sometimes bags are subject to contamination because there may be a defect in the baglike a pinhole or bad heat seal in the bag. For the most part bags are reliable but just be gentle with them and not force air in and out ofthe bag and you should be good.

Rye Grain Spawn Bag Organic (2 lb)10/18/2023
A few speed bumps but great customer service.
I ordered a grow bag bundle but was disappointed when I saw that one of the two bags was defective and came with a hole in it. I reached out to the company and they assured me it was an unusual occurrence and sent me TWO new bags as a replacement. Very happy with how they responded and fixed the situation.

Excellent product
Love using these. No contamination ever after dozens of times using them. Love keeping them in my fridge until I’m ready to use them. The shipping speed is incredible even though I’m multiple states away.

Good product!
The product is good. The shipping is a little wonky. Goes from North Fort Myers to Tampa, then to South Ft Myers. I wish there was a local pick-up option.

Have great success with this company. The shipping is great and is here the next day. The mini all-in-one is great because it’s the perfect size and you get the right amount when used properly.
