    Nutrients and Fertilizers for Growing Cannabis

    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.

    Delta 9 Cannabiogen

    Delta 9 Cannabiogen is a leading cannabis flowering fertilizer that stimulates and speeds up the flowering period, and increases the yield, as well as its quality. It also promotes terpenes creation, improving flavors and aromas.

    Bloombastic

    Bloombastic is a product design for the plants’ last stage. This product features the sugars and carbs, as well as a high PK content in order to grow larger flowers with more resin and THC.

    Get the best organic nutrients for cannabis at GB The Green Brand

    If you are looking for ecological growing products for your plants, avoid mineral fertilizers and focus on organic nutrients. These will provide amazing flavors and aromas while feeding microorganism to the soil.

    Organic Iguana Juice Grow

    Organic Iguana Juice Grow is a 100% organic fertilizer specifically created for growing cannabis plants. This product encourages root growth and promotes taller and stronger plants capable of absorbing more nutrients, in order to prepare them for a very successful flowering period.

    Top cannabis fertilizer 

    GB The Green Brand sells only top quality fertilizers and nutrients, therefore, it is hard to decide which one is the best one. After consulting with experts in the matter, we’ve concluded that Delta Boom gathers everything a good cannabis growing fertilizer should offer.

    Delta boom

    Delta Boom is the perfect fertilizer for the flowering period. Its amazing formula, rich in Ascophyllum nodosum, vegetable amino acids, carbohydrates, enzyme activators and vitamins will boost the yield to its full potential.

    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

    Humic Boom is a solid organic fertilizer suitable for both growth and flowering, therefore growers won’t have to invest on another product if money is tight. This additive improves root development and nutrient absorption, which has a positive impact on the final yield.

    FAQ about cannabis fertilizers

    When to fertilize cannabis?

    It depends on the growing method you are using, the strain, and the phase that the plant is in. Depending on the phase your grow is in, your plants are going to need certain nutrients in higher proportions, so if they don’t get them through irrigation, then they will probably end up showing deficiencies.

    What nutrients do you need for growing weed?

    Cannabis needs more nitrogen in growth, as well as phosphorus, and potassium for the flowering period.

    Can I grow weed without nutrients?

    While it is possible to grow weed without nutrients, it is not recommended doing so as your plants may not receive the nutrients that these products provide to guarantee a good quality yield.

    How often to give cannabis nutrients?

    You can water your plants twice a week using Boom Nutrients. There is a growing schedule perfectly designed to guide you during the growth process of your plants.

    What nutrients do cannabis plants need?

    NPK stands for nitrogen (N), phosphorus (P), and potassium (K). These are the basic elements that ensure a proper development of plants, cannabis included.

    How to fix nutrient burn on weed plants?

    Overfeeding your plants may cause damage to them. If your plants are not reacting well, we recommend cutting off all nutrients and using just water for a week or two. Burnt leaves won't turn green again, but you can clip the burnt bits off, or remove them if they are completely damaged.

    What is the best fertilizer for cannabis?

    In our catalog, there are lots of options in regards to choosing a specific fertilizer for your plants. To learn more about the best cannabis fertilizers on the market, you can give a quick look to this TOP 5 Best cannabis fertilizers article.

    When to stop giving cannabis nutrients?

    Stop using Boom Nutrients at about 15 days before the seed bank states that your plants’ should finish up flowering, or if your plants show any signs of nutrient burn.
