5 Stars Great Stuff

I like all the additives in it and that it is from a renewal able resource and I cheated and got the stuff with the gel to hold water so my stuff wouldn't dry out.

5 Stars great addition & compact

Easy to store, stackable. Plants seem to love it, I had a great winter harvest! Buying more for my spring planting. I try to keep some on hand so I always have soil to add to my beds. A bit pricey but doable with free shipping

5 Stars Wonder Soil is Wonderful!

This block takes up much less space than comparable bags of potting soil. It is light weight, feeds the plants and uses less water than potting soil. I love it and will be buying more.

First bought it because I got a discount. Started using just coconut coir and really liked it. Then I saw Wondersoil with additives and bought 3 cubes. Just hydrated my last block. WISH I had MORE! Wish you weren't so far away---freight!
