How To Make Your Own Marijuana Fertilizers

How To Make Your Own Marijuana Fertilizers

Marijuana fertilizers come in all shapes and sizes, and most of them achieve the desired effect of producing better marijuana plants with better yields. 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. Download my free marijuana grow bible at this link and learn more about making fertilizers!



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.

By John on 20 March 2014

When i see all of these organic fertilizers these guys are using, it reminds me of all the pills i take for pain and other problems. It makes ya wonder if it’s really woth it, i know the pills aren’t, that why i’m going GREEN.

Urine (diluted 7 parts water to 1 part urine) works great for lawns, vegetable gardens, and fruit trees, so it is not surprising it would promote healthy weeds. I keep a water bottle in the garage to keep well hydrated while working outside in the yard and garden. I drink water when thirsty and immediately after urinating into a bucket I keep for that purpose. Then I dilute the urine and empty the bucket before evening wherever it seems there is the most need.

i’ve read a lot about this and it does all really pointing at urine being great at being a real good fertilizer. i do have a question though and would be interested in getting any feedback etc from anyone who knows (or thinks they know, the question is i take a lot of medications for something i will never get any better anyway i’m wondering that it could get into my plants and i really d ont wanna add to my health probs! anyone out there with answers? thanks and have a nice day :- )

This might sound out there but using urine from a sick person to grow fruits, vegetables,
Weed or anything else that sick person might want to consume might end up being a taylor
made cure from Nature !
Nature has the ability to know that something is wrong in the Urine and respond by creating
a plant much stronger and possibly your own personal cure ?
Worth a try !

Hey Mark,

Urine can save your life in the wilderness; It is full of nutrients.

By latewood on 24 June 2015


I am sorry to here of your affliction. I am not a Dr. With that said; I have to think that if you have an issue that is making you sick, I would restrain from using my urine for nutrients. There are many inexpensive nutrients online that you could use. Check out this site 🙂

I have a plant that is about a month old and I noticed the leaves were turning yellow so I mixed my urine with water and fed the plant, the next day it looked droopy, I thought I killed it but the next day all the leaves were a beautiful green and it looked amazing, wow, who would have thought piss would be the food of the Gods for cannabis, thanks

If you use urine, do you still need other fertilizer?

By jdub on 31 August 2016

I prefer a good 5 gallon bucket filled with Diarrhea for fertilizer keeps the soil conditioned as well just mix it in the soil with your hands cheers!!

By Roy ILGM on 2 September 2016

Thanks for the tip jdub, hope it works for you

That’s going way to far for fertilizing.

By Kelly on 31 January 2018

That’s going way to far for fertilizing using poop.

First Time using a fertilizer, my step dad says fish guts mixed with potting soil. Will that work with the urine?

By latewood.ILGM on 20 April 2017


Personally, I would not use fish guts because they will attract all kinds of pests. Fish meal, or Fish emulsion would be a better choice.

Are egg shells irie to use?

By latewood.ILGM on 25 May 2017


Egg shells are great to add to a compost. I would not advise just dumping egg shells directly into garden. compost them 1st. Happy growing!

By ALIEN IN YOUR BUCKET on 13 June 2017

Using emergency blankets instead of store bought mylar excellent alternative price 40 dollars roll mylar blanket 1 dollar. 4ft × 4ft × 8 ft. 1 blanket. Try it works great !!

By Rathebe on 21 June 2017

Guys ive been trying to grow this electric broccoli for 4 months with no luck until some dude told me to add potatoes to my soil, as it rots it serves as food for the plant, I have a one month old baby now and I think im going to add this urine tip for good measure, hope it wont kill my plant

By chuk on 13 July 2017

remember your urine will expel all sorts of things, fine for a plant outside grown direct in soil, but I wouldn’t recommend it for potted plants. I found this article to be unhelpful and trying to sell something for some affiliate cash
