The ultimate cannabis nutrition when growing with coconut potting soil

  • Give it throughout the entire growth and flowering phase

Combine Cocos A&B with all Universal Plagron products. For example, use Power Roots, Green Sensation, and Pure Zym for the very best results.

Using Cocos A&B:

Cocos A&B is a two-component nutrient that cannot be used separately. To use Cocos A&B plant nutrition, shake the bottles well first. Then add a maximum of 4 ml of Cocos A to 1 liter of water (1:250). Use exactly the same amount of Cocos B with each dose of Cocos A. Mix them together in one water solution before giving the mix to your plants. After mixing the nutrition with the water, adjust the pH value.

A ratio of 1:250 is the maximum dosage. However, the ideal dosage depends on the phase your cannabis plant is in. Consult the "Plagron Cultivation Schedule for Coco" to determine the ideal dosage for your cannabis plant. You can find the cultivation schedule on the Plagron website.

Note: Cocos A&B can only be combined after they have been mixed with water. Do not add both at the same time to the water, but one by one.
