  1. Rated 5 out of 5

    Great product and great price. I used it to stop blossom end rot in hydroponic system, that developed after changing to new food. used 1/2 tsp. per gal. I got Immediate results.

    1/2 tsp. per gal = 100 ppm
    1 tsp. per gal= 200 ppm
    1 tbspn. per gal = 600 ppm

  2. Rated 5 out of 5

    Blossom end rot has been a continual problem since we moved to this location. Our old place had soil with a limestone parent material but this one is more shale and lacks calcium. A few years ago we learned about adding calcium and had acquired a small supply of Calcium Nitrate from another supplier. It helped significantly but when it ran out, I had trouble finding a source until I happened upon Kelp4Less.

    The Kelp4Less formulation has a smaller granule size and it seems to absorb moisture more quickly so I have to keep the bag tightly closed. I mixed it with the starter fertilizer and mixed that with the soil before I planted my peppers and tomatoes this year. We have had some exceptionally wet weather lately but when I checked on the tomatoes today there was not a (knock on wood) hint of blossom end rot on anything. I’m glad that I don’t have to worry about organic certification because I’m sure this would be considered a chemical fertilizer but I won’t try to grow tomatoes or peppers without it.

  3. Rated 5 out of 5

    I run an aquaponics system, and find calcium levels to be a major issue. Using calcium carbonate and bicarbonate won’t get enough calcium into my issue, so I use Calcium Nitrate. The product provides the much needed calcium, and a little extra boost of Nitrate. Every day I toss a Tablespoon full in.
