How to Use Your Supplies

  1. Prepare in Advance: When buying or preparing your own supplies, store them for 10-14 days before using to ensure they're clean.
  2. Maintain Cleanliness: Treat prepping a tub like surgery - you can't be too clean. Use 70% alcohol to clean your tub, gloves, masks, and any other equipment. Work in a clean space with no circulating air.
  3. Gently Incorporate Spawn: Avoid handling your spawn and substrate with bare hands. Gently pour the spawn into the substrate bag, being careful not to let the two bags touch. This prevents cross-contamination.
  4. Mix Thoroughly: Once the spawn is in the substrate bag, pinch the bag closed and give it a good shake or massage to thoroughly mix the contents together. This ensures even distribution.
  5. Transfer to Tub: Carefully transfer the mixed spawn/substrate into your clean tub. Flatten the surface of the substrate using a clean metal spatula or similar tool.
  6. Set and Forget: Once the tub is prepared, simply "set and forget" - no further handling is necessary.

By following these steps, you can ensure a clean and successful mushroom growing process.

Amazing substrate!

I have so many great things to say about this sub. The finest quality and fast shipping. Super fast colonization and monster fruits. Customer service is the absolute best. Trust me, look no further than APlusGrain for your sub and grain needs.

Damn this manure slaps!!!

Got some to test along side my own blend. It went crazy right off the bat. Was super fast to pin and produced some chonky bois. Real deal stuff. Glad I got a chance to run it and can’t wait to run it again.


Monster fruits

This stuff is worth it. I used aplus oats that colonized so nicely and then spawned to this alpaca blend sub and it was colonized within like four days. This was one of my favorite projects so far. This stuff gave me a packed canopy of monster fruits. Absolutely going to be getting more. I highly recommend this sub

Looks good so far !

One of my mono tubs was fully colonized just after a week, the other isn't far behind. Can't wait to see what fruits it'll produce with the alpaca and bunny poo !
