This has been my first experience buying bulk soil and I have yet to yield any results from my soil but the buying experience has been top notch. NAO has all kinds of ingredients sold by the yard. They mix your custom blend and they deliver it to you at a very reasonable price. The selection is great and the staff is very knowledgeable. Certainly much more cost effective to build your own custom bulk potting soil vs. buying it individually by the bag. If the soil kills my plants I'll be back to edit this review but I'm so far confident in the product and happy with the convenience and $ saved.‎
