CVG Mushroom Substrate | Dry Bulk Substrate for Mushroom Growing | Makes 10 lbs of Pasteurized Substrate | Perfect for Monotub Grows | Coco Coir, Vermiculite, Gypsum

This is a great, convenient kit, the only issue is that the amount of water is WAY too much. I had to wring out the substrate prior to putting in the tub.

Mix is clean and free of contamination. Holds moisture very well. Mix is easy to make and can be use in grow bags and tubs. Can be used for different types of mushrooms. Mushroom grow really well in the mix. Can be used in different size grow bags and tubs. Mix can have extra things added like compost, ashes, straw, sawdust and others. I would buy this mix again.

I was very happy with the kit. It arrived early and is very affordable and is working out well for me. I was able to make 2 12 quart tubs with the kit. My only complaint is that the recommended water amount was way to much . Will definitely be purchasing this again soon.

This is good and convenient, but after buying one of these, I went and bought a 10lb block of coir, large bags of vermiculite and gypsum, and spent far less to make far more substrate. I prefer a coarser vermiculite than what came in this kit. The super fine vermiculite gets all over everything and it's a pain to remove. The mushrooms I grew with this mix did fantastic, so the mix is good, just too expensive for a serious grower.

Clean. Worked well thank you!

Perfect for making substrate for mycology. Although I did have a contamination when using this product. Instructions were very easy and the price wasn't too bad. I just wasn't very happy with the outcome

No mold growth but my spores were bad and did not populate. Will try again.

After noticing that the mixture is wetter then it should be by following sufin spores directions for the product after 4 different times i decided to measure each product gypsum is sopost to be 200g but while still in the original packaging I found the weight to be 202g after package was dumped out it only weighed 195g also found that coconut coir and vermiculite where also off by about 16g each i went to sufin spores website and purchased 2 more and weighed each one and found that they are off by 8-18g each while I understand you can't have perfection every time I believe it's more off then correct while this doesn't seem like a big deal since you can alway add more coco coir to soak up the extra water it means you either need to use less water when mixing you cvg or buy extra to add witch also cost more money

Overall it is good for starters, but watch some YouTube videos just to make sure. For me the amount of water in instruction was a bit more than it needed.
