  • Handmade
  • Materials: spawn, sawdust, soybean hull, sterilization, micronfilter, filter patch, injection port spore syringe

These are the best grow kits on the market. We offer two types of substrate to best meet your growing needs.

For tree-loving species, we use a secret blend of sawdust, soybean hull, gypsum and love. This blend is great for growing gourmet edible mushrooms

For the dung lovers, we use a beautiful blend of coco coir, soybean hull, rye, and vermiculite. Great for dung loving gourmet mushrooms

Both are packaged in a high-quality PPE bag with a high-grade micron filter and high-temperature self-healing injection port. Be sure to research your gourmet species

This is a TWO BLOCK sterilized substrate kit with self-healing injection ports.

Each has an injection port where you can insert a syringe (sold separately) without risking contamination.

Be sure to be as sterile as possible. If you need us we offer phone support via 304-303-5514 CALL US WE WANT TO TALK TO YOU (unless it is really late then I'm sleeping, or trying to)

This is perhaps the most full-proof method for growing mushrooms without risking contamination.

Each block can yield several lbs if the correct environment is maintained using a humidity tent, tub, or grow room! For some species simply inoculating is enough!

Your species may grow faster than others sometimes it takes months

Instructions:
1) clean your area like crazy. SUPER CLEAN
2) flame sterilize the needle of your spore syringe with a lighter. FLAME ON
3) inject with 2cc's of your desired strain then pull out slowly. For added protection, you can add tape over top of the port. SAFETY FIRST
4) then simply set the sealed block in an area that has the proper temperature for the mushrooms to colonize PATIENCE
5) wait till your block is colonized with mycelium, of course determining this depends on your species, but for the most part the block hardens and turns white. This may take a few weeks MYCELIUM=ROOTS (But cooler)
6) Once it is colonized wait for it to start pinning or for baby mushrooms to start popping up. LITTLE DUDES
7) After wee mushrooms pop out. Open it and spray those bad boys with water twice daily SHOWERTIME
8) Pick mushrooms before the caps curl all the way up YUM

This block is contamination resistant with the proper skills! Each block is equipped with its very own high-grade micron filter and is already impulse sealed

Great for beginners and experts alike! This kit is great for tree loving species.

All you have to do is wait for colonization and you will be amazed.

The weight is approximate. Please reach out to us if you feel your blocks aren’t large enough and we’ll send some more. Really if you have any problems reach out we’ll help you. We want your repeat business and to help you get growing. Bud

My package had some kind of white looking mold in between the tape on the back of one if the blocks, this is my first purchase from this seller. I am a bit disappointed, I hope I didnt just waste my only 2 spores!

Appearance looked great. I tried 3 different sterilized grow bags from different companies. Unfortunately it's nearly 5 weeks later and I'm barely starting to see some mycellium, whereas another has been fully colonized (btw that was a 4lb bag). So unsure if i got a bad batch or what. But a little unhappy for the grow progress thus far.

So far I have only used one bag out of the four I purchased. It is doing wonderfully, the bag had signs of mycelium three days after inoculation. I imagine the other three bags are going to work just as well. Great product and a very easy no drama experience, I am very pleased.

Innoculated 4 blocks, 3 we're showing mycelium growth after a few days, the 4th took about a week to start, but that could be a spore issue and nothing to do with the bag. All 4 blocks are now going like mad and no contamination! Excellent product.This is my go to store front for mushroom bags from now on! Thank you for producing a great product!
