Just a grower
Awesome quality

This is my first time using coco choir and I have very happy with the product. Shipping was fast and The rehydration of the product was great. I did expect a bigger yield of soil by about 20 gallons. However I would definitely purchases the 10lbs blocks again. I bought 4 10lbs blocks. I used 3 and got 50 lbs of soils.

All was as expected. Which may not seem like a great review, but having ordered from you several times, I have never been disappointed in any way, which IS remarkable.
