Premium Bulk Mushroom Substrate - 5 lbs Expert Mycologist Blend of Coco Coir, Vermiculite & Gypsum, Pasteurized & Odor-Free, Long Shelf-Life, Ideal for Monotub Cultivation

Been using this cvg substate for the last two years and it has been working wonders .Best price substrate for the quality and ship time for sure i will be re ordering in the future!

Great substrate! Fast delivery, substrate came clean and colonized fast! Been making my own sub for 10 years and this product is a great way to save time!

Do Not Buy This Product Anymore The Last 3 Bags I've Gotten Have Had Trichomiderma All My Bins Were Sanitized Before And During The Process Of Spawn To Bulk In My Monotub I've Had 4 Successful Grows Using This Product Months Ago But Now It Seems They Don't Care About Sterilization Anymore

Best substrate in the game...moisture content on point n great packaging couldn't ask for a better product...surfin spores is second to none!

This substrate worked out very well, no contamination, perfect field capacity. Mixed with my colonized grain it produced 3 flushes no problem. Great price, Great moisture retention and the perfect size for 3 pounds of grain.

Worked great! Will buy again.

I only used this a couple of times, not bad. I prefer the dry mix your own stuff though. If you like going this route, it's a great product. Always clean, never an issue when I've used it.

Quick shipping. Substrate looks good, moisture content is on point. Mixed it with my spawn one day ago and it’s already showing signs of life. Highly recommend this substrate.
