Understanding the inconsistencies in your water quality can make all the difference in achieving a successful harvest. Make sure you check your water and, if needed, correct its mineral balance using CANNA CALMAG AGENT's highly concentrated solution of calcium and magnesium at the ideal 3:1 ratio. You'll be able to create the perfect start point to then apply your CANNA TERRA or COCO base nutrients to get the most out of your grow.

Find out how to check your water quality and how best to treat it on CANNA's dedicated water testing page at canna-uk.com. Alternatively, contact your local store, which may be able to provide a more localised insight for your area.
