One of the downsides of organic marijuana growing is that it takes time for the microorganisms thriving in the soil to develop and establish their colonies to help you enjoy massive yields. But with a healthy dose of patience and the right know-how on homemade organic cannabis plants fertilizers, you can boost yields all naturally without spending a fortune (and in fact, you may not even spend a single dime)!
Did we already manage to grab your attention? Great, because we can’t wait for you to join us below and take advantage of the ultimate list of DIY organic cannabis fertilizers that we have tried and tested in time with dedication and pure love for the green medication.
Composting: The Most Natural Way to Make your Marijuana Plants Flourish
Now, let’s get things straight from the very start: even the best homemade organic cannabis fertilizers will fail to be fully utilized in an inert growing medium. The real magic happens when the essential nutrients present in organic fertilizers get in contact with the microbial life in the soil.
But in order to help the microbial life develop and thrive, it is best to forget about tilling soil.
Even if you are an indoor grower who is concerned about the possible pathogens that may get inside your house when you use rich, organic soil – fret not, bud buddies! Instead of using animal manure enriched compost you can simply choose to stick to the vegan versions on that matter, and you won’t be the least disappointed.
The drawback to going for no-till cannabis cultivation in soil and getting into composting is that the process is, indeed, time-consuming.
You can’t just throw food scraps straight into your cannabis plants’ containers and watch them grow dense, juicy, multiple sugar-coated nuggets in the blink of an eye. In nature, all beautiful things take time.
But once you take the time needed for the process of composting to be fully and successfully accomplished, you will soon realize that every single effort spent, including the waiting, is well worth it in the long run.
By choosing to compost, you will learn how to recharge soil all by yourself and finally get out of the vicious spiral of lugging bags of soil in and out just for the sake of having to buy new bags for each grows operation. You can pretty much think of composting as recycling old, depleted soil and watching in turn into rich, fertile soil within a couple of months.
For best results, start composting and recharging the soil in the late autumn season as to be 100% ready to plant your green beauties in spring. Don’t forget to check out the pH balance and adjust the levels if needed as you don’t want to make your marijuana plants suffer because of too highly acidic or too highly alkaline soil.
Quick Heads Up: Remember that no matter how hard you try and how much love, attention, and dedication you put into your cannabis growing operation, you won’t be able to get the final results you are dreaming of in the case you don’t use high-quality seeds. As small and fragile a cannabis seed may seem at a glance, it is right inside this tender, tiny body, where the secret key to a bountiful harvest resides, the secret key being none other but strong genetics.
DIY Organic Fertilizers for Every Stage of Marijuana Plants’ Growth
Ask any experienced marijuana grower about a good and affordable fertilizer that will help your green ladies turn into green queens during the vegetative stage of growth, and you will most likely receive no other advice but to go for urine.
Well, it may sound a bit gross, at least when you are just being introduced to the idea of using your own urine to feed your marijuana plants. However, the truth is, there is barely anything more natural than optimizing the magnificently growth-boosting properties of urine.
In the living nature, it is the essential nutrients obtained from the urine of various animals that your plants can take advantage of. Anyway, the fact that you can use your own urine is even better for you can rest assured that no animal-borne disease will possibly get in contact with your precious plants.
Urine is a fantastic natural fertilizer during the vegetative stage of your cannabis plants as it is very high in Nitrogen. What you need to remember is that urine must be diluted (the ratio is 10 part water for 1 part of urine), or else, you may easily burn your plants and cause unwanted harm.
Also, you want to be careful when watering with the homemade urine fertilizer as not to get it directly on stems, foliage or leaves. Even when diluted, it can still burn the foliage of cannabis plants. Simply water it gently into the soil, and you’re good to go.
Finally, don’t pour the entire 10 parts of water to 10 parts of urine fertilizer at once. This quantity will be enough for roughly 2-3 feedings which are best to take place every other day or so.
2. Coffee grounds
Coffee grounds can make a beautiful organic fertilizer for cannabis plants during each stage of their growth but are best suited to use during vegetation.
That’s because coffee grounds possess a balanced ratio of Phosphorus and Potassium but it is Nitrogen which is present in the highest rates.
Coffee grounds are great to add to your compost, too, and they break up very quickly.
Furthermore, coffee grounds come with a superbly balanced pH level that cannabis plants simply adore (coffee grounds’ pH is very close to neutral and typically varies from 6.5 – 6.8).
However, when it comes to organic cannabis fertilizers, all you have to do is place coffee grounds in a clean bottle and fill it with water following a 10:1 ratio (10 parts of water for 1 part of coffee grounds).
Leave the bottle in a cool, dry place and let the coffee grounds dissolve for about a week (7-10 days works best). Next, strain the fertilizer using a cheesecloth and feed it to your hungry marijuana plants. Similarly to the urine fertilizer feeding routine, it is best to avoid using the coffee grounds fertilizer on two consecutive days.
3. Coconut flesh and coconut water
Coconut water makes a brilliant cannabis plants fertilizer that is not only 100% natural but it also doesn’t require any fancy preparations or waiting in order to take advantage of.
Simply cut a fresh coconut in half and pour the coconut water into the soil of your plants. The pH of coconut water is usually about 6.3 but it can vary with +or – 1.5 so it is a good idea to keep track of the pH level and balance it out if needed. For instance, you can add urine to raise the pH level.
Keep in mind that coconut water is best to be applied during flowering as it is very high in Potassium (in fact, it contains more Potassium than a total of four bananas!)
As to the flesh of the coconut fruit, it makes a no less impressive and well-working organic fertilizer for your precious green ladies. All you have to do is to scoop out the flesh of a coconut and add the pieces into a clean bottle full of water. Use as much water as to cover the pieces of coconut flesh with about 2 inches. Let the coconut fruit release its nutrients in the water for 5-10 days, making sure to place the water container away from direct access to sunlight.
You will need to strain the coconut particles before feeding your marijuana plants. For best results, feed every other day or so. Coconut flesh can be used both during vegetation, as well as during flowering.
Interestingly, extensive research on the potential of using fermented coconut water as an organic fertilizer conducted by the Department of Chemical Engineering, Indonesia, has found out that one can manipulate the Nitrogen to Phosphorus to Potassium content depending on the days spent in fermentation.
Letting coconut water ferment for more than 5 days lead to a decrease of Potassium and Phosphorus levels and letting it ferment for 10+ days lead to an increase in Nitrogen levels.
Using molasses as an all-natural, organic fertilizer for your cannabis garden is one of the wisest steps you can take in order to enjoy sufficient yields.
Molasses can boost the rewards you get upon harvesting with about 15% – 20% on an average, and that’s generally because of the bigger buds it helps marijuana plants to produce since it is rich in sugars, as well as essential elements. In a nutshell, adding molasses greatly benefits the microbial life in the soil.
The most important thing you need to remember when mixing a batch of molasses cannabis fertilizer is to apply it in the last stages of vegetation.
For best results, feed your green ladies molasses about 1 week before you switch to flowering and opt for un-sulphured molasses.
Feel free to add 1 and up to 2 tablespoons of molasses per 1 gallon of water.
Last but not least, a molasses cannabis fertilizer can be an especially mighty tool when growing hybrid strains; to be more specific, when growing modern-day, top-quality hybrid strains from seed as many of these are known as heavy feeders.
