Best Cannabis Fertilizers and Nutrients – Reviews & Guide

Growing cannabis at home has become more and more popular in recent years as more US states and countries around the world change their laws in favor of legalizing cannabis. With its many uses medically as well as recreationally, the weed business has boomed. Buds can be smoked, vaped, cooked, and made into oils and lotions to relax the muscles.

With all the ways you can use and consume cannabis, it is important to start out with a good quality product to get the most out of each usage. If you are growing your own weed at home, then the way to ensure a good quality bud at harvest time is to feed your plants with all the correct nutrients they need to grow healthy and strong.

In the rest of this article, we will review some of the top marijuana plant fertilizers currently on the market, so that you can buy the product that best suits your grower needs.

#3. Botanicare CNS17 Bloom 2-2-3 Formula

Suitable for both cannabis and other plants, this fertilizer has had many positive reviews. The formula comes in bottles of up to one gallon, which is enough to feed an entire grow room.

Product Highlights

The Botanicare CNS17 Bloom formula can be bought in bulk for a good price on Amazon (1 gallon for $23.30, or five 1-gallon bottles for $94.91), which makes this a good product for those who like to grow on a large scale. This formula is a professional strength product, so a little goes a long way, and it has been developed especially for flowering and fruit-bearing plants. The precise blend of 17 minerals will keep your plants well fed without giving them any nutrient burn or nutrient overdrive.


#4. Fox Farm FX14049 Liquid Nutrient Trio Soil Formula: Big Bloom, Grow Big, and Tiger Bloom

These three formulas from Fox Farm are almost on a par with Advanced Nutrients in terms of positive reviews in the weed growing community. Each of the three formulas has a special blend of nutrients that will help your marijuana plants grow to the fullest in each stage of their development. Fox Farm say to use Grow Big at the start of your plant’s life to help it grow lush, green vegetation, and to switch to Tiger Bloom as soon as your plant starts to show signs of bud development. Big Bloom is used throughout the entire growing cycle of the plant to aid nutrient uptake.

Product Highlights

This line of Fox Farm products has been known to produce larger and greener marijuana plants, as well as having formulas specifically dedicated to the later stages of growth, which lots of fertilizer companies do not do.
