coco coir

Coco Coir

Our premium Coco Coir is a key ingredient in our substrate mix, weighing 850g. Sustainably sourced and organic, coco coir provides excellent moisture retention and aeration properties, creating an ideal environment for mushroom mycelium. This fibrous material not only supports robust root development but also maintains structural integrity, ensuring your mushrooms have the perfect base to thrive.

vermiculite

Vermiculite

Our 400g bag of Vermiculite is a crucial component of our substrate blend. Vermiculite increases aeration and moisture retention, facilitating optimal mycelial growth. This natural mineral helps maintain necessary humidity levels and prevents compaction, promoting consistent mushroom cultivation and enhancing yield.

gypsum

Gypsum

Incorporate our finely powdered Gypsum into your substrate to ensure your mushrooms receive essential nutrients. Weighing 200g, gypsum is a vital addition that conditions the soil, providing calcium and sulfur to help stabilize pH levels and improve the structure of your growing medium. This addition promotes healthier, more prolific mushroom fruits.

substrate

I love that it comes all together and I didn't have to stop at 3 stores to get it myself. I used the bucket tek pasteurization method and it worked great!

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.

Had I seen the amount provided, I would have just stuck to the CVG recipe and purchased ingredients individually. At best, this will do 3 6qt shoe box tubs. Way too expensive. Returning this and I just purchased on Amazon 5lbs of gypsum, 10Lbs of Coir, and 30 QTs vermiculite for under $85. Thats over 10x the amount provided in this kit.

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.

Unfortunately, the directions I followed on the packet that came with the box left the substrate extremely wet. I didn't feel like squeezing all the excess water from it to get it to the proper field capacity, so I threw all of it in my garden. What a waste. I should have just followed Philly Golden Teacher's CVG recipe instead of trying this garbage. Will not be buying any of their products again.

Surfing’ Spores makes it super easy to produce pasteurized healthy substrate. Their excellent pre measured packages of C V & G plus easy to follow instructions and fast shipping are so worth the price. And, their added sticker is adorable! Will be buy again today. Great results for this happy camper. Highly recommend. They also make inflatable tubs with the best price on the internet. Thank you, Surfin’ Spores 🍄💕
