Many fertilizers range from relatively common store-bought substances to somewhat outlandish, but easily accessible resources. Whatever you use, it’s important to understand the value of fertilizer for the marijuana plants.
Cannabis relies on fertilizer to get its valued nutrient content. Without any nutrients (food), the plants will end up withering away to nothing. Just having water and light won’t be enough to get your plants thriving. Fertilizers can go a long way in doing just that. But, what are the best fertilizers to use?
There is some logic behind sticking with a proven formula. For years, garden centers across the world have sold Miracle-Gro and other packaged fertilizers at relatively inexpensive prices. Using these fertilizers is a tried and true method that has worked for a variety of different gardeners for a variety of different plants. These fertilizers also give you the added benefit of listing the amount of nutrients they have in the soil.
For instance, most store bought fertilizers work off of a standard ratio between nitrogen (N), phosphorous (P), and potassium (K). This is called an NPK ratio and it lets you know exactly how much you’re feeding to your plants.

One of the strangest fertilizers you may have ever heard of is human urine. Indeed, the yellow stuff is chalk full of the nitrogen that can promote stem and leaf production. It is important to not urinate directly on the marijuana plants or even near the plants because it might kill where it touches. This is because the urine has too high of a concentration of nitrogen for it to be safe. That is why it must always be diluted in about a gallon of water and then used quickly. If it’s not used soon after the solution is made, then you run the risk of ammonia forming which could infect and kill the plant.
Of course, another relatively inexpensive and also tried and true method is composting. Composting is nature’s way of really highlighting the circle of life. Any organic material you might have lying around in your backyard is sufficient for composting. This can take the form of stashed away dog feces or it can be the product of decayed oranges from an orange tree. You could even combine different organic materials that have been lying around for months or years at a time. Although it might strike you as a gross way to make a fertilizer, it is one of the best and most natural ways to produce a thriving crop.
There are more options for fertilizers that you might want to try, but these are certainly three of the best (or at least the easiest to use). Whether you’re peeing in a bottle or going down to the garden center to buy a bag of pre-made fertilizer, you’re going to increase your marijuana yield with higher nutrient content. In the end, that’s all you’re really looking for when it comes to fertilizers.
