SOFT WATER
Low in calcium and magnesium.
IDEAL WATER
Moderately hard to hard water, containing appropriate calcium and magnesium levels and typically has an EC ~0.2-0.4.
VERY HARD WATER
High in calcium and magnesium.
BAD WATER
High in sodium, chlorine, heavy metals, harmful elements, or has a very high EC. Bad water is bad water, hard or soft.
SOFT WATER
Water that is naturally soft or has gone through reverse osmosis contains very little calcium and magnesium. CANNA CALMAG AGENT can be used to increase water hardness.
IDEAL WATER
This water is moderately hard to hard, contains an appropriate quantity of calcium and magnesium, and generally has an EC ~0.2-0.4. All CANNA products are designed to work best with this type of water. No need to use CANNA CALMAG AGENT.
VERY HARD WATER
To use very hard water, some growers use a reverse osmosis (R.O.) filter, which turns it to soft water. Use this R.O. treated water with CANNA CALMAG AGENT. Or, if your original water is free from contaminants, it can be mixed with your R.O. water till you reach an EC of 0.2-0.4.
BAD WATER
Water with high levels of sodium, chloride, or other harmful elements can block the uptake of nutrients or even be toxic to your plants. A reverse osmosis filter can be used to treat this water - make sure it's effective!
