Love wonder soil

Not only is wonder soil competitively priced they are the only amended coco coir with more than NPK and for the same price and of most other coco coir bricks that don't even have any amendments added to them! I found them last year and so glad I did!!

Annual garden requirement

Wondersoil is the *only* coco coir w/nutrients I have found/will use to start my seeds. As a no-excrement, organic Garden/farmer, this mix has led to *at least* a doubling of my annual yields. Every year, it's expected that at least some seedlings will not grow into productive plants. However, I have yet to experience a single failure in the past 2 years of Wondersoil use. Rather, I've had to give away a lot of strong, healthy plants. I wish this magic coir came by the truckload!

Hi Mindi!
Thank you for your review! We are so happy our Cubes had met all your expectations!
Happy Gardening!
