If you use a coco substrate to grow your plants, then you should be using House & Garden Cocos nutrients as well.
House & Garden Cocos nutrients are a two part A & B formula, which are used for both the growth stage and flowering stage of your plants and they contain Humic and Fulvic acids, which help with the uptake of the nutrients through the plant roots and root hairs and also the transportation of the vital nutrients within your plants.
Lush healthy growth can be achieved with just these coco nutrients and during the flowering period you can use additional House & Garden additives and boosts to help stimulate and increase the final size and weight of your crop.
How To Use
Add equal amounts of House & Garden Cocos A + B into the water and test the strength with an EC meter to ensure it is at the correct EC level for the stage of your plants.
