Great savings
I'm very pleased by the savings enjoyed by purchasing the granules instead of premixed solution. It mixes quickly with water and has been an excellent plant supplement.Thanks!

Good Value
Contents of package have some heavily clumped crystals, which may be the reason for instructions to not split into smaller batches. Contrary to instructions, we ground clumps, mixed very thoroughly, and divided for smaller batches. Stuff works great. Really helped my tomatoes and peppers!

Best bang for the buck!
Dry is the only way to go. The price per ounce is worth it alone. Anyone growing in Coco coir should look into this. Cal Mag Plus Concentrate mixes well and stays suspended in solution for a long time.

No more blossom end rot!
I grew 10 varieties of tomato in 10 gallon landscape cans in a generally soilless mix. These are maintained in a hoop house with open ends. In years past I have had big problems with blossom end rot. This year I added gypsum and epsom salts at planting as usual plus some calcium nitrate. I watered in with Neptunes Harvest tomato fertilizer plus Cal-Mag Plus. I then ordered from Greenway Biotech their tomato fertilizer and Cl-Mag Plus powder. I fertilized once a week and added Cal-Mag with every watering. I have the best and biggest tomatoes ever and zero blossom end rot! Now my only problem is the tomato eating chipmunk who has taken up residence in my hoop house. I am very pleased with the Biotech products and their shipping service.

Really good, mix with warm distilled water.
It works really well it come out to be the exact same concentration as Cal Mag Plus. Except this is 2 gallons purchased instead of one gallon of the Cal Mag Plus

Great product/price, better for the environment.
I really like that I'm not paying to ship water around. When I can, I try to get as much dry stuff as possible, when things come prediluted it seems so wasteful!The price is great too! My plants seem to notice no difference between this and the calmag I used to buy. I use this to buffer my coco before and in between "hydro" grows. Thanks!

Super cheap calmag!
Ends up being a gallon + ~500ml, so have another container ready. I mixed it in a five gallon bucket so I could really churn it. No complaints from my plants.
