    Great product. Works as good as any premixed cal-mag products I’ve purchased or better. I feel like a lot of hydroponic companies use this same blend and just mix it with water before selling it for more.

    I’m a fan of this CalMag Organic. It mixes instantly and is very very very easy to use. Most importantly when I use it my plants responds with in 24 hours. Which means it’s plant ready. I’ll never use another CalMag Supplement.
