Blue Butterfly Popcorn Grain Spawn Bags

Gorilla Mushrooms™ Blue Butterfly Popcorn Grain Spawn Bags are ideal for inoculation of your mushroom spores when you are looking to grow in bulk substrates. When paired with our Bulk Casings or Bulk Substrate(s) like the “The Original S*it Bag™” and fruit them in our MycroGROW™ Kit or MycroGROW™ Auto, you will have created the perfect recipe to grow some Gorilla Mushrooms™!

Bulk growing tips & Instructions:

Grain spawn bags are not what you will want to fruit. To fruit with a grain spawn bag, purchase or make a bulk substrate and casing! You will colonize the bulk substrate with the grain spawn once the grain spawn is fully colonized. Grain spawn bags colonize very quickly and provide nutrition for mushroom spores prior to using the grain spawn to colonize the bulk substrate. Once the grain spawn is colonized, thoroughly mix it in a tray or your mushroom kit with the bulk substrate. Then top it off with a 1/4″ – 1/2″ casing layer. Once you see 30-50% of the casing layer colonized, turn your mushroom kit light on to initiate pinning of your mushrooms. Ensure your casing layer is sprayed daily until pinning starts. 

Only the best:

Gorilla Mushrooms™ Blue Butterfly Popcorn Grain Spawn Bags are made with only the finest locally sourced 100% Blue Butterfly Popcorn. Clearly these guys are no joke as test samplers have reported back up to 100% colonization in as little as 2 weeks! If you’re looking to step out of the sandbox and put down the PF Tek cakes and dip your toes into the deep end of the proverbial pool, doing so with our Popcorn Spawn Bags is the key to unlocking the massive growth that you’ve been waiting for.

Samples tested by real customers. Sample grows are done by first time mushroom growers. We want your expectations to be realistic. So, we won’t blaze your retinas out with the Gorilla Mushrooms grown by our very own Psilly Gorilla, but with pictures of Gorilla Mushrooms grown specifically by first time growers who own a FAME KIT.
