Cannabis fertilizers range from sets used in sequence to those with claims of superiority when it comes to growing large, potent buds.
Selecting a fertilizer can seem like a challenge, but this list may be of some help in choosing the right fertilizer.
Foxfarm Liquid Nutrient Trio Soil Formula: Big Bloom, Grow Big, Tiger Bloom
Used in sequence, growers first start with Grow Big, a liquid concentrate fertilizer used to enhance plant size and structure, then switch to Tiger Bloom at the first sign of flowering.
Big Bloom can be used throughout all growing cycles to heal root systems and increase nutrient cycling although it’s ideal for mature, late-season flowers.
Big Bloom contains bat guano, used for centuries as a fertilizer and earthworm castings to create a nutrient-rich mix. Plants should be fed up to two times per week.
Advanced Nutrients: Big Bud Liquid Fertilizer
Big Bud claims to increase the size and potency of marijuana flowers. It’s proven worldwide to maximize potency better than any other booster.
With use flowers will be larger, heavier, and denser with more essential oils, aromatics, terpenoids, phenols and other potency factors. It contains L-amino acids, phosphorus, and potassium.
Advanced Nutrients: Bloom, Micro, Grow
Growers will not have to worry about the pH in their nutrient solutions because this three-part hydroponics fertilizer is able to adjust the pH to the optimal range automatically, increasing yield.
Advanced Nutrients also promotes the fastest growth possible.

Real Growers Recharge
This organic plant growth stimulant is loaded with mycorrhizae, trichoderma, and beneficial bacteria with kelp, humic, fulvic and molasses.
Recharge works on organic gardens for fast growth. It contains billions of beneficial living soil microbes that load up depleted soils with organic nutrition. It’s designed in Colorado and should be used once a week.
The mycorrhizae fungi grow to naturally protect the plant while delivering water and nutrients to the root system.
The trichoderma species of fungi in Recharge have been selected because of their high tolerance to chemical fertilizers. These trichoderma species are aggressive decomposers and break down organic matter within the soil and make it available to the plant.
But the star of Recharge is the beneficial bacteria. Bacillus subspecies act as billions of stomachs, digesting and converting soil matter into nature’s perfect slow release plant food.
Makers supercharge their Recharge with high quality ascophyllum nodosum kelp extract and provide an unsulfured blackstrap molasses as a food source.
