Bought for my DWC cucumber %26 tomato

Came in good shape. Was suggested by some of the hydroponic blogs I've been following. Easy enough to use and includes a “recipe” of MasterBlend, epsom salts, calcium %26 water. MasterBlend dissolves mostly but takes a bit of effort to dissolve it completely. I've only used it for a couple of top offs so we will see how it does. I imagine it will be a big help for my plants. Most of the information from other hydroponic growers are happy with their results. I was offered $5 to write a review before I could actually test the product.

very good product

This fertilizer is for the plant to produce blooms and set fruit. Only need use once or twice a year. I like how easily this brand mixed! The results speak for themselves. Bigger, Stronger, Better taste!
