The best fertilizers and nutrients for cannabis
Our customers are always looking for a bountiful and delicious harvest, this is why they use our finest quality selection of fertilizers with all the nutrients and trace elements that are required to boost the growth of their plants.
Types of cannabis fertilizer
There are different types of cannabis fertilizer: organic, biomineral or chemical, and mixed fertilizers. Organic fertilizers are made up of organic matters from animals or plants. Biomineral or chemical fertilizers have their origins in labs where the essential macronutrients are isolated for each stage of cannabis development. However, more and more fertilizers contain some macronutrients. Mixed fertilizers have a completely organic part, combined with some macronutrients.
Best outdoor cannabis flowering fertilizer
When it comes to growing seasonal plants outdoors, flowering products should be used from the moment that your plant is continuously spewing out pistils. Plants grown at the start of the season outdoors should begin to flower from the start of July onwards. Plants grown a bit later can take until mid-August to begin flowering.
Bio·Down
Bio-Down is an organic pH reducer designed to be used in ecological and organic growing without harming the environment. This fertilizer will allow you to keep the substrate of your plants in the best possible conditions, as it contains a high amount of citric acid extracted from organically grown lemons.
Fertilizer for cannabis plants indoor
When it comes to indoor growers, fertilizer products can be used starting the first flowering week. However, we highly recommend waiting until week two, when growing indica-dominant or pure indica strains. When growing sativa strains or sativa-dominant strains, we recommend starting from the third or fourth flowering week.
Bio Grow
Bio Grow is a 100% organic growth fertilizer that will give your plants everything they need to grow nice and healthy. You can use other stimulants and additives by other brands, but if you want to increase root growth and increase your plant size and final yield, combine it with Root Juice.
Best Nutrients for cannabis plants
Here is a list with GB The Green Brand’s best selling weed fertilizers, especially created for growers who trust our choices and don’t like to take any risk.

Organic Iguana Juice Grow

Best cheap cannabis nutrients
If you are on a budget but realize that your plants will perform better with a little bit of extra help, we recommend Humic Boom. It’s a cheap but efficient fertilizer.
Humic boom
