Keep note of the amounts of nutrients and additives you add to each tank of nutrients you mix. You then have a good starting point for the next time!

If you are using CANNA RHIZOTONIC always add this to the feed water before you adjust the pH; CANNA RHIZOTONIC is a natural pH plus product.

When you dilute an acidic product, always add the acid to the water, never add water to the acid, if it splashes it will cause burns on your skin or in your eyes!

Do you want to raise or lower the pH by using pH+ or pH-? Then dilute a small amount of pH+ or pH- in a cup to make judging the dosage easier. Try to get the pH right the first time. Using a lot of pH+ or pH- one after the other will disrupt the concentration of bicarbonate in the water and affect its buffering capacities negatively.

Measuring the nutrient reservoir works as follows: Take EC as the starting point, measure it and determine whether it should be higher or lower, based on the values shown in the instructions. Only then should you adjust the pH using pH- or pH+, if necessary. Try to get the nutrient solution’s pH value correct at the first attempt.

The products designed to adjust the pH are concentrated products. It is sometimes difficult to adjust the pH correctly in one go. To make life easier for yourself, dilute one part pH adjuster with ten parts water and use this to adjust the pH in your nutrient tank.

Using too much pH+ & pH- with each other disturbs the bicarbonate concentration and the water’s buffering capacity. Also, the mutual balance between the different nutrient elements will be influenced and deficiencies could arise. Adding too much pH- or pH+ can be prevented by first diluting it with water before adding it to the solution.

Do not place too many plants per square meter; plants will generally become larger on CANNA Coco and will need more space than on e.g. rockwool or potting soil.

Light breaks down iron chelates! Because of this, it is very important to ensure that no Ultra Violet light falls on the nutrient solution. Light also causes algae to grow in the nutrient solution, which can lead to blockages. Furthermore, algae can take up nutrient elements and cause nutrient deficiencies to occur.

Take your time diluting and adjusting your nutrient tank! This is essential for the growth, flowering and development of the plants and will yield the best results.

When cultivating in plant trays with a sealable drainage system, it is easier to begin by making the drainage incisions, then turning over the COGr and filling the plant container with the buffering solution.

It's not necessary to water with CANNA Coco in advance of planting. It is recommen­ded to drip the coco with nutrient solution (2 ml CANNA Coco A & 2 ml Coco B /litre; pH 5.2-6.2) until drain appears. The coco now contains enough nutrients and water for a couple of days. Furthermore, the right temperature (20-25 °C) and high air humidity guarantee an optimal start.
