There are dozens of different fertilizers to choose from in the market; growers can choose based on budget, nutrients needed, location, season, and much more. But <a href=\"https:\/\/cannabis.net\/blog\/how-to\/what-is-the-best-poop-to-put-on-your-cannabis-plants\">not all fertilizers are made equally<\/a> \u2013 of course, some are of better quality than others.<\/p>\n<p>That said, there are some rather <a href=\"https:\/\/cannabis.net\/blog\/opinion\/should-you-fertilize-your-cannabis-plants-with-coconut-water\">unusual fertilizers<\/a> that can be used on plants. These may include, but are not limited to: coffee, milk, grass clippings, banana peels, fish tank water, potato water, and even urine! Yes, it does sound strange, but to gardening enthusiasts, there is nutritional value to be found in each of these things, which can make them suitable fertilizers depending on the circumstances.<\/p>\n<p>For example, grass clippings make excellent mulch and can provide potassium, nitrogen, and phosphorus. Urine is a potent source of nitrogen as well as phosphorus. Banana peels are rich in calcium, which is excellent for promoting root growth while helping supply oxygen to the soil.<\/p>\n<p>But what about bat poop? Also known as guano, bat poop has been said to work as a plant fertilizer because it\u2019s rich in nitrogen, potassium, phosphorus, and other nutrients. Unfortunately, using bat poop as a plant fertilizer can also be dangerous. So if you don\u2019t really know what you are doing, bat poop as a fertilizer can be extremely risky.<\/p>\n<p><strong>Bat Poop Fertilizer Kills 2 NY Men<\/strong><\/p>\n<p>On December 2024, news of two men hailing from Rochester, New York, dying went viral.<\/p>\n<p>The cause of death was dangerous fungus, in the bat poop that they were using to fertilize their marijuana plants. Both men grew their own marijuana plants for medical consumption, but unfortunately developed histoplasmosis after breathing toxic fungal spores from the guano.<\/p>\n<p>One of the men was aged 59 years old; he bought bat poop online to use as fertilizer for his plants. Meanwhile, the other was a 64-year-old male who found guano in his attic, then decided to use it to fertilize his cannabis plants. They both developed similar symptoms, including chronic coughs, fever, severe weight loss, and respiratory failure. The case was also discussed in the <a href=\"https:\/\/academic.oup.com\/ofid\/article\/11\/12\/ofae711\/7917418?login=false\">Open Forum Infectious Diseases<\/a> medical journal.<\/p>\n<p>Is there a safe way to use bat poop as fertilizer? If you ask me, I truly can\u2019t understand why one would use guano as fertilizer when there are so many other proven safe alternatives out there that are simply not as risky. According to the <a href=\"https:\/\/depts.washington.edu\/hortlib\/pal\/safety-of-bat-guano\/\">University of Washington<\/a>, one must always wear a dust mask each time you open a bag containing soil amendments. That\u2019s because a mask will greatly decrease the chances of breathing in fungal spores, which could be potentially dangerous. They also go on to explain that yes, guano is indeed used as fertilizer for its valuable nitrogen content but it still isn\u2019t without its own risks, particularly of developing Histoplasma \u2013 the same condition that killed the two men.<\/p>\n<p><strong>Make Your Own Safe Fertilizers At Home<\/strong><\/p>\n<p>There are many other safe, affordable \u2013 and even free \u2013 <a href=\"https:\/\/cannabis.net\/blog\/how-to\/seaweed-fertilizer-for-cannabis-plants-a-powerful-superfood-for-marijuana-plants\">fertilizers<\/a> you can feed your marijuana plants with.

When the coffee grounds decompose, they create soil aggregates that improve soil aeration and its water retention capabilities.<\/p>\n<\/li>\n<\/ul>\n<p>Mix around 2 grams of coffee ground for every liter of soil. Measuring its pH levels is also helpful, since you want it to be between 6 to 6.5<\/p>\n<ul>\n<li>\n<p>Crushed eggshells are a great way to ensure no eggshells go to waste. It\u2019s rich in calcium plus other minerals that are effective in improving overall plant structure, health, and growth.

Just mix eggshells into the soil, or steep them into water then pour into the soil for a calcium-packed feed.<\/p>\n<ul>\n<li>\n<p>Banana tea or water is rich in potassium and magnesium, making it perfect as a feed during the marijuana plant\u2019s flowering stage. You can use banana peels differently: with 3 to 5 banana peels, soak it in water for 2 days. Then you can use the water on your plants, and even leave the banana peels as compost for your garden.<\/p>\n<\/li>\n<\/ul>\n<ul>\n<li>\n<p>Wood ash from your fireplace or other sources is a great source of phosphorus and potassium. Simply sprinkle some wood ash over marijuana during the final flower phase. Just use 1 or 2 grams of ash for every liter of substrate. Be careful not to use too much wood ash, or it can make the soil too alkaline.<\/p>\n<\/li>\n<\/ul>\n<ul>\n<li>\n<p>Animal manure, such as those from cows, rabbits, or horses, make excellent organic fertilizers.
