Cannabis, like any other plant, may also need extra help for better growth.
There are natural fertilizers that you can make yourself in a simple way.
Most plants can use a fertilizer or organic substrates to help them grow healthy, vigorous and full of vitality. Natural fertilizers have been used for centuries and have served to obtain abundant, disease-free crops with spectacular growth as they provide the plant with all the minerals and organic compounds it needs to grow healthy and strong.
Here we show you some of the best known and best results give for the crop of our beloved plant. 😉
However, if you prefer to use fertilizers available on the market, remember that in our “Fertilizers and Stimulants” section you can find them at the best price.

A fertilizer for the growth phase
The use of coffee grounds as a natural fertilizer has long been well known, and it is also one of the most commonly used homemade marijuana fertilizers.
Coffee grounds are acidic and favour the development of acetic bacteria in the substrate, containing about 2% nitrogen and other organic nutrients.
A good way to prepare a good fertilizer for marijuana is to add the coffee grounds to your compost or composting tank, or spread them and mix them with the substrate that will be in contact with the roots of your plant, but you should control well the pH because they can leave the substrate too acidic.
Another way to use coffee is to dilute the coffee ground from the coffee machine in one liter of water, and let the mixture stand for 24 hours. After this time we already have a good dose of fertilizer for our plants. In this case, we do not use the sediment directly as fertilizer, but the mother water (water in contact with the unsoluble coffe ground) derived from the digestion of the sediment (sedimented coffee).
Fertilizer for the final flowering phase
Always using wood from broadleaves trees; it’s another good natural fertilizer for marijuana. We can get the wood ashes from a barbecue made with logs or from a chimney in which we use only wood. The result of the wood combustion is a substance rich in potassium and phosphorus (10% in the form of potassium oxide), so we have a mineral fertilizer suitable for the final flowering phase, used individually or combined with some resin enhancer.
One way to prepare the ashes for fertilization is to collect it soon after the wood has burned and store it in a dry place. It’s best to apply mixed with other organic substrates as it is almost exclusively a mineral residue. Ashes are also very effective in preventing pests.
And now you may irrigate your cannabis plants in flowering phase with the nutrient solution. Another of the most useful homemade fertilizers for your collection.
Full cycle flowering fertilizer
This fruit is known for being one of the most potassium-rich natural products. Potassium is a key element, which is used in all stages of cannabis plant development, and is also one of the three main macronutrients component of NPK (you can see it on the label), which we can all see in regular commercial fertilizers.
Potassium helps the plant assimilate sugars, starches and carbohydrates in general, which is why it is so essential for the plant’s flowering, as it helps to increase energy reserves and the construction of complex carbohydrates that give structure to leaves, stems and buds.
Potassium is also essential because it is associated with the biosynthesis of proteins related to terpenes, the absorption of water by the roots and the regulation of the stomata cell guards for its opening and closing.
In addition to this essential element, banana tea also provides amino acids assimilated by the plant so that we can say that it is an organic-mineral fertilizer.
This tea is applied during the last six weeks of flowering. With this you will get up to 20% more fattening in your buds. You can also do it using honey, or molasses from sugar cane instead of pure white sugar.
A good fertilizer for marijuana, without a doubt, one of the best.
Fertilizer of foliar application and preventive insecticide
Nettle tea (urtica urens) rather than a fertilizer is a product that provides active plant principles of repellent activity on insects such as aphids, whiteflies and mites, but can also be considered fertilizer because of its high content in organic nitrogen and mineral components.
Its application is foliar and it is very easy to prepare since we only have to follow the same steps as in the preparation of banana tea.
We may cook a good handful of nettles in a litre of water and the liquid obtained (already strained) is used to irrigate the plant.
It has a strong and characteristic smell, even there are brands of biocides/fertilizers that commercialize this type of preparations or fertilizers for cannabis as Agrobeta or General Hydroponics, even labelled as deficencies correctors . You can find it with the denomination of “Purín de ortigas” in Spain.
It’s a great product that enters us into organic agriculture as good natural fertilizers that they are.
Brewer’s yeast has normally been promoted as an excellent food for human use, but due to its wealth of minerals, amino acids and proteins it has been proposed as an excellent organic-mineral fertilizer, qualified also as a good natural fertilizer for plants.
How to use it to make organic compost for marijuana plants?
The preparation we can make for fertilizing consists of a small spoonful of brewer’s yeast dissolved in a liter of water, we will get another good fertilizer, in this case for cannabis in flowering phase, because it is very rich in phosphorus and potassium. Due to its high content in other minerals and organic compounds we consider it as a multipurpose fertilizer… Just use it!
Calcium deficiency correcting fertilizer
An excellent calcium corrector that we can use in our preparations with marijuana fertilizers are also the homemade egg shell-based fertilizers.
This type of fertilizer is used to provide extra calcium to our marijuana plants. It is prepared by crushing in a mortar among six to eight eggshells, which are then put to digest using a litre and a half of water with a few drops of a diluted aqueous solution of hydrochloric acid (you may find as Salfumant name in Spain) for 24 hours. You must measure the pH of the resulting nutrition solution that should remain around 5.0.
After that time, the remaining shells are removed and the resulting liquid is filtered.
We already have our calcium-rich fertilizer for our marijuana. Calcium deficiency is not very common in marijuana, since it is a very common component in irrigation water that is not distilled or osmotized, but bear in mind that the marijuana plant requires almost as much calcium as nitrogen, and that is why many commercial brands of fertilizers for hydroponics incorporate it in their formulas.
Mix the resulting nutrient solution with some fertilizer rich in nitrogen for the growth phase, or phosphorus and potassium for the flowering phase, although you can use it as calcium corrector directly as long as you take into account the pH value.
Full cycle fertilizer
Although it may not seem too pleasant, animal faeces are one of the most universal fertilizers for marijuana. It is a high-quality organic fertilizer. In order to use this type of homemade fertilizer for plants, it is necessary to collect the dried animal faeces from species such as sheep, goat, horse, rabbit, and cow, some bird species are also suitable, including the famous Guano, which is obtained from bats.
Before using this type of fertilizer, you must compost it for two months or more before adding it to the substrate of your garden, since the composting process may kill the seeds of bad weeds and transforms the nutrients into more profitable nutrient form by the plant. It is a fertilizer for marijuana quite complete in macronutrients and trace elements, one of the fertilizers for plants of general use for the entire cannabis vegetative cycle.
Lentils or bean tea
Root stimulants rich in auxins
Auxins represent a very important group of phytohormones that regulate plant growth and phototropism (movement of leaves and stems in search of light), causing the branches to grow vertically by elongation of plant cells.
Auxins have been traditionally used in gel form for root development in cuttings and seedlings, as is the case of Clonex, one of the best known marijuana products, and although it is true that the Auxins work very well in synthetic form, we can also find them in nutrient solutions formed by organic products such as seaweeds, and teas made of seeds rich in auxins, as happens with certain species of beans and other vegetables.
The teas made with these natural products are simple to prepare, as they are simply based on leaving the vegetables in water for a day, until they are completely hydrated. We can also heat this blend a little to help extract the nutritious compounds, then whisk it together and the resulting paste is strained. The final water or nutrient solution, contains the nutritious extract rich in auxins, and will be ready to use on roots and cuttings.
