No matter how you plan on cultivating your marijuana seeds, you’ll need to add cannabis fertilizers to aid the growth of your plants for better yields. While there are plenty of synthetic products on the market, you can create a natural solution with the same benefits.

In this guide, we list the 10 best organic fertilizers for cannabis for an abundant yield. You’ll learn what nutrients these byproducts offer and how your plants benefit from them. Let’s get started.

 

Going green with organic fertilizers

Before we get into the different types of cannabis fertilizers, it’s worth understanding why you should choose organic materials over chemicals.

The most noticeable benefit of using organic cannabis fertilizers is that they release nutrients slower. This means a lower chance of overfeeding your plants, making it a fantastic option for beginners.

Another advantage of these natural byproducts is that they are far more cost-effective than chemicals. Some of these cannabis fertilizers are already available at home, allowing you to turn waste into a useful tool.

The final benefit of these organic nutrients is that they provide a more balanced ecosystem. They help microorganisms in the soil flourish and, in turn, keep your plants healthy throughout their growth cycle.

10 natural cannabis fertilizers

There are tons of brilliant organic fertilizers for cannabis available in stores and even at home. To start you off on the right foot, we’ve put together a list of the 10 best natural options to ensure an enormous yield.

 

Blood meal

As the name suggests, this fertilizer for cannabis comes from dried animal blood that’s turned into a powder. It’s a brilliant way to add more nitrogen to your soil, especially in the vegetating phase of your crop.

It can also help increase your plant’s resistance to pests and frost. If you own dogs, you might want to put up some protection, as they tend to dig up the soil due to the smell.

 

Bat guano

Many people are familiar with using dung as a way to enrich the soil. One of the most versatile is bat guano fertilizer for cannabis. This organic compound helps improve the soil quality as well as its drainage, working well with Afghan feminized seeds.

Bat guano is a great way to put more phosphorus into your plants. It’s one of the best outdoor cannabis fertilizers as it speeds up the vegging stage and increases yield. As you might expect, this organic material carries a strong aroma, so handle with care.

 

Wood ash 

If you’re in need of additional potassium, look no further than wood ash. Instead of throwing away what’s leftover from your barbeque, use it to help your weed plants. Either sprinkle small amounts on your crop or mix it with your compost for a future harvest.

It’s one of the best soil fertilizers for cannabis as it assists seeds in the early stages of growth. Another benefit is that it helps improve your plant’s water efficiency.

 

Bone meal

Bone meal is a trusted cannabis flowering fertilizer. It comes from grinding up animal bones, usually from the humble cow, and then mixing it with your soil. By doing this, you’ll increase the levels of phosphorus available to your crop.

With these additional nutrients, you can strengthen the stems of your marijuana plants. This is a vital step before your crop begins to create heavy colas, like the ones you can expect from Green Crack feminized seeds. It‘ll also help to avoid diseases as it increases your crop’s resistance.

 

Fish meal

One of the main types of nutrients required for a strong weed plant is nitrogen. Thankfully, fish can assist your crop by adding this essential mineral. Fish meal is a byproduct of fishing, making it readily available throughout the year.

It’s not only a good fertilizer for cannabis flowering, but it also assists with photosynthesis. You’ll need to use caution when applying fish nutrients, as too much can cause burning and slow down growth.

 

Kelp meal

We’re staying by the sea for this next entry. Kelp meal comes from dried-up algae and seaweed, providing your plant with essential nutrients at every stage. It’s very safe to use, allowing you to sprinkle the powder around the base of your marijuana stems.

Kelp meal is a great source of potassium, making it a reliable cannabis flowering fertilizer, especially when growing Grapefruit feminized seeds. You’ll want to keep a bag of it handy, especially in colder climates, as it helps your plant build up resistance to frost.

 

Dolomite lime 

If you’re struggling to correct the pH level of your soil, look no further than dolomite lime. Before you use this cannabis fertilizer, you should test the soil’s acidity. That way, you’ll know the correct amount to add.

It’s a good source to gain additional calcium and magnesium, vital for strong, healthy plants. Lime dissolves slowly, so it’s best to add it to your soil four weeks before planting your seeds.

 

Epsom salts

Epsom salts is a powerful cannabis flowering fertilizer, as it can dramatically enhance the quality of your bud. Not only is it easy to get your hands on, but it’s also an excellent source of magnesium and sulfur.

This organic compound quickly dissolves into water, allowing you to add it to your plants effortlessly. Applying this solution twice a month to your Blue Widow feminized seeds will bring out vivid colors and increase yield.

 

Chicken manure

You can use chicken dung as a fertilizer for cannabis. It releases its nutrients slowly, allowing your plants to stay strong and healthy. This manure is a brilliant source of nitrogen, phosphorus, and potassium, making it a great pairing with Skunk feminized seeds.

Like most dung fertilizers, it’s best to add this to your compost heap as raw chicken manure can burn or even kill your crop with its high nitrogen levels.

 

Compost

One of the most cost-effective ways to get quality nutrients to your plants is by starting your very own compost heap. It’s crazy to think how many great cannabis fertilizers we throw away on a daily basis.

Whether it’s banana peels, eggshells, or leftover veggies, you can add them to your compost pile. In return, you’ll receive one of the best organic fertilizers for cannabis around. Every marijuana cultivator should practice this sustainable option as it’s great for plants and the planet we call home.

Create organic liquid fertilizer for hydroponics

Using natural byproducts to strengthen your marijuana plants is simple enough. This task becomes slightly more difficult when you plan to use a hydroponic setup. Don’t fret, as we’ve also got a solution for you liquid fanatics out there.

The answer to organic hydroponic cannabis fertilizers is to create a tea. To do this, you’ll need to fill a bucket (about a quarter full) with your chosen natural nutrients. From here, you should add water and let the solution stand for a few weeks.

Finally, place a cloth in a colander to filter the solids and pour the solution into another bucket. Now you have a potent tea ready to enrich your growing trees.

If your chosen byproduct is already in liquid form, you can add it to your solution and let your plants soak in the goodness.

 

Keep your plant happy, and it’ll reward you

It’s clear that there are many healthy alternatives when it comes to cannabis fertilizers. They provide similar nutrients as chemical solutions but with added benefits. Some byproducts require a bit more effort to prepare them correctly, but the extra work will pay dividends in the end.
