Dry Mushroom Substrate Mix | CVG (Coco Coir, Vermiculite, Gypsum) | Produces 11+ Pounds of Pasteurized Bulk Substrate for Monotubs and Mushroom Grow Bag

Have bought and used several of these kits, they are the best! Ingredients are great quality, come individually packaged ready to mix and the instructions provided make it easy for anyone to understand and feel comfortable mixing their own substrate for the first time. The results from this substrate mix have been MASSIVE 🙌 🍄Comparatively, the price is great too which definitely doesn’t hurt!I’ll keep using OlympusMyco substrate and will for sure be trying more of their products in the future!

If you follow the intructions to the letter you will get everything you ever wanted out of this substrate. it is consistently better than others that i have found and produces great harvests

Easy-peasy to prepare with instructions included,printed on a big laminated notebook sized card..Its as easy as boiling some water and mixing the contents in a 5gallon bucket,put the lid on and you are done!..Definitely be back for more 😀

Sooo none of it was at the proper weight at all which put the directions unable to use i had to modify the recipe for what I used it for…

You can tell there great qaulity versus others I’ve bought, and there on point what they say is there will purchase again thank you

followed directions. it was so wet i tried to dry it, squeeze it, but still think it ruined this ? I thought this was a mushroom company. dont make the same mistake

The instructions call for 1 gallon of water and the substrate was almost mud. Way too wet and almost impossible to dehydrate without risking contamination. So I asked for a replacement. Amazon wanted the mud back so I packaged it up and returned it. ( I also just got an email saying I DIDN'T return it and had to contact Amazon today to clear it up) The replacement substrate arrived quickly and I reduced the water to 3 qts and 1 cup which was perfect field capacity and used distilled water that I boiled at 10 PSI in my pressure cooker for 10 minutes. I have North Spore boomer bins and used this substrate on two. I used 8qts of perfectly colonized grain jars in each monotub, pure white with zero contamination and 16 days later threw it all away due to Trich and some kind of pink stuff. I did much better buying my own coco coir, gypsum, and vermiculite.

Was perfect amount for my 66 quart monotub, had no contamination in my set up, easy to use
