    Quality products at great prices. I was very pleased with how quickly my order shipped and was received. The bags they come in are a heavy material and reseals perfectly on the first try every time. I use this in my aquariums and it mixes clear. Overall great products!

    Good quality at an excellent price, with speedy shipping. Bag reseals well. Research shows that at 50 ppm KNO aids begonia seed germination.

    My order arrived fast and in great condition. Love that the ferts are packaged in their own resealable bag so you don’t have to go find your own. Product appears very pure and mixes right in.
