Do not plant too many plants per square yard; 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 reaches 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.

Keep a record 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!

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.

Check and adjust the nutrient reservoir as follows: Take a reading of the EC/ppm and pH of the nutrient solution and then determine whether there needs to be adjustments. Use the EC/ppm reading to determine if your concentration needs to be higher or lower, based on the values shown in our grow guide. Use the pH value to determine if an adjustment is needed and if so, try to correct the pH value at the first attempt!

Water with CANNA Coco fertilizers till 10-20% drainage is achieved. Water again with nutrient solution once the plant has consumed 50% of the nutrient solution originally applied. OR, follow along an irrigation schedule based on intended steering goals.

Calmag is recommended when using RO water or soft water on coco substrate. It may also be used depending on plant genetics.

We recommend to use PK 13/14 always for one week when you use CANNA nutrients. The CANNA base nutrients already contain sufficient P and K during the rest of the cycle. There is a certain period during the flowering stage though, when we can't increase the feed for the plant any more, so we adjust the PK-ratio by adding PK 13/14 for that one week.

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.
