  • Organic Rye Grain Spawn Bags (2)  - RSB1

Rye can be a tricky grain to master. Our carefully chosen organic rye is soaked for 16 hours in an alkaline mineral water and then slowly simmered to maximize the water content. After simmering the grain is fortified with gypsum and allowed to dry and then bagged and sterilized for 180 mins in our autoclave at 20 PSI. This higher autoclave temp ensures all endospores left in the rye grain are destroyed. Our bags are guaranteed to arrive fresh and sterile.

Each order of Rye includes Two Bags and features: 

  • USDA Organic Rye Grain
  • 2 Quarts of Spawn (2.5lbs each)
  • Self-healing high temperature injection port
  • .22 micron filter patch
  • Heavy Duty Spawn Bag

    This was my first experience growing mushrooms ever and I’m very happy I went with these bags from mycolabs! Spawn colonized quickly with no contamination. If you’re looking for an easy way to get your cultivation going, these bags are perfect and take a lot of the stress off of having to sterilize the grain yourself!

    Best ive used!

    Best Spawn bags I've used! -- The moisture is just slightly visible and the bag is clean and folded in the perfect dimensions to protect the injection port. The packing tape was hard to differentiate from the bag. I've inoculated them and just staying patient for the first sight of mycelium.. big thanks to Brian for the great advice and tips! Mycolabs is beyond 5 stars for me!

    The RYE Bags have extremely High yield!!

    These grain bags are awesome. Very high yield with three grows. I tried the jars also, just like bulk method, which I made myself and I did have a failure once, the grain soured probably my lack of skill.
    I put all 4 bags out with spores and no temperature control. In an incubator I get visible colonization in just days! Really good stuff here

    10/10 Success!

    10/10 bags colonized!! I have to say this has been the best experience I’ve had since I started researching. I received the spawn bags last week and they arrived packaged professionally making sure to keep the bags from getting contaminated. I inoculated the bags on Friday it is now Thursday and the growth of mycelium has surprised me. The bags are a little under halfway colonized and I couldn’t be happier. If you’re looking to buy spawn bags don’t look anywhere else because you will be thankful you purchased from Mycolabs they are the best bar none.
