Awesome product, arrived fast and clean.
Great shipping time as always! Love you guys!
This was way better than a normal CVG! I usually pastuerize my own CVG but i had no coco coir left , so i just bought this substrste because i had spawn ready to go and this was the quickest way to get that going! The micelium grabbed hold much quicker with this substrate . I was very surprised and extremely happy. I would buy again
