Canna Calmag Agent

PRODUCT DETAILS

Canna Calmag Agent is a buffering additive that is designed to be added to soft or RO water to make your tap water more suitable for hydroponic use.

If you live in a soft water area (if the EC of your tap water is less than 0.4) then Calmag Agent will help you bring your water up to what Canna consider normal, or optimal, for use with their products. They state that their UK nutrients are designed to be used with water that has a base EC of 0.4 - 0.7 as this is the background EC range that will give the best results when using their nutrients.

Canna Calmag can also be used to give RO water a decent buffer level and bring the water back up to a point where using the standard Canna Nutrients are possible, without this buffering the pH of the solution will be very hard to control.

Canna make some of the best nutrients on the market, getting your base water into the zone that they formulate their nutrients to work best with makes a lot of sense. If you have soft water or use RO water and also use Canna Nutrients, this product is a no-brainer.
