When we mix nutrient solutions, we need to follow the feed chart recipes to arrive at the correct NER. The correct NER is important for plant nutrition. After mixing the solution we need to make sure the total mix is not too salty for the plant. We do this by measuring the EC. The correct EC is important because it affects Osmosis. Be sure to read our tutorial, “How to Mix Nutrient Solutions for Cannabis”.

Plant roots require both oxygen and water. If the roots are starved of oxygen, they will turn brown and die. Soil based growing media become oxygen depleted when they are saturated with water. This means that the roots are unable to get enough air for some time after each watering. Growers need to wait for soil to dry out before watering again because otherwise the roots will not get enough oxygen and they will die.

It is possible to practice high-frequency fertigation in coco when hand-watering, but it requires a commitment. Coco should not get dry; therefore, it is important to fertigate at least once per day. If you are hand-watering, you should think carefully about your ability to commit to once or twice daily fertigations. However, if you are willing to commit to at least once daily fertigation, you can start to unlock the magic of coco.

When EC and NER are balanced, fertigation fulfills the plant’s water needs and delivers nutrients to the plant in their most easily absorbable form. The plant has access to everything it needs, all the time, at the correct ratios – and growth explodes!

Nutrient Element Ratio (NER)

Electrical Conductivity (EC), is a measure of how saline (salty) the water is. EC, PPM, and TDS are all different ways to express the same basic measurement. I explain all of the details of EC, PPM, and TDS in our article, “Understanding EC, PPM & TDS for Growing Cannabis”. Be sure to also see our tutorials, “EC/PPM Targets for Fertigating Cannabis” and “How to Manage your Cannabis Grow by Measuring Run-off EC”.

When hand-watering you should plan for a 5 or 7-gallon final container. These are large enough to allow you to maintain an acceptable EC and NER balance with only once or twice daily fertigation. If you can manage twice daily fertigation, then the 5-gallon final containers are best. If you think the most you can do is once daily fertigation, then use 7-gallon final containers. Be sure to read our article “Transplanting Cannabis Plants: Why, When, and How”.

Coco coir has many properties which make it a horticultural wonder. It is easy to manage, offers plants excellent growing conditions, and does not interfere with nutrition. Among the most important horticultural properties of coco coir is its air to water ratio.

Coco Coir is a Horticultural Wonder

A tremendous amount of confusion exists in the cannabis growing community about how plants interact with water and nutrition. It is important to understand that although you mix the nutrients with the water, the plant takes them up separately. Water is pulled across root membranes through osmosis and nutrients enter the plant separately, through diffusion, passive transport, and active transport. The plant receives water and nutrients through different processes, and they must be balanced.

Effective fertigation is the key to maximizing the speed of growth and the size of harvests. Understanding the five key principles of high frequency fertigation will allow you to manage your coco grow like a pro!

Don’t forget your CalMag supplement, Calmag Plus or the GH CaliMagic combo, or else you will likely see Ca and Mg deficiencies.

Most manufacturers will tell you they sell the best coco coir. They can’t all be telling the truth. We’ve always had good luck running Canna coco, but there are others that will work just as well. Look for bagged coco that is washed and pre-buffered.

Dyna-Gro Nutrients

Amendments include Canna Rhizotonic (a rooting stimulator), Cannazym (breaks down dead roots and improve plants’ nutrient uptake) Canna Boost (a flowering enhancer), and Canna PK 12/13 (a phosphorous and potassium booster during flowering).
