Great results
I use this fertilizer on onion plants in tall raised beds every two weeks before they start to bulb. Then no fertilizer at all. This one keeps them making huge foliage and they stay dark green and growing great even after I stop the application and only water every day a little. Very good fertilizer and I have used it for several years. I will buy more.

Excellent CaNO3 (calcium nitrate) fertilizer
Excellent CaNO3 (calcium nitrate) fertilizer. Very pure, with granules consistent in size. Not inexpensive, but probably the best form of nitrate you can buy, especially during the winter when ammonium toxicity is a concern.

Very effective, just follow instructions
I mix it in my sprayer and feed once every couple of weeks my leafy plants and seedlings responded with noticeably greener foliage. The calcium component also seemed to help my tomatoes avoid common deficiencies I’ve seen before. My only small gripe is that you really have to measure carefully and avoid overuse, or it can be strong on sensitive plants. Still, if you want a good all‑around nitrogen plus calcium boost, this does the job.

It is a clean grade, easy to dissolve.
This is a nice clean dissolving product. It loves to absorb water from the air, be sure to seal it up air tight immediately, and do not use thin plastic bags. I tried a different brand (yellow and red) from the local garden store, which along with being a local source was half of the price per pound. But it was coated in a thick layer of terrible smelling petroleum gloop. Probably to reduce water absorption in handling and storage, but I wouldn't want it in my soil and it would quickly cause problems in a hydroponic system.

Best soil amendment for fertilizing tomato pksnts
I have found that calcium nitrate is the best solution to preventing blossom rot in tomato plants. Use 1 tsp. per gallon of water on potted plants or 1 T. Per gallon on field planted tomatoes. Also great on pepper plants.

Best hydroponic supply and super fast shipping
This is one component of the Masterblend trio for hydroponic solution, and a useful fertilizer otherwise. These folks seem to be the main distributor for Masterblend and they've always been awesome on all counts. I've been using this in my hydro greenhouse for years and couldn't be happier.
