How to make your own weed fertilizer at home? [In Simple Steps]

If you love DIY things then you are going to love this guide. As there are many ways by which growers usually make their own fertilizers for their cannabis plants. 

And, you can also make it on your own!

Within a few steps.

However, before we head to the step-by-step guide, the fertilizer we are going to make is the FFJ or FPJ (Fermented Fruit Juice/Fermented Plant Juice). You can choose either of them as per convenience.

Although for creating FPJ (Fermented Plant Juice), gardeners prefer nutrient-dense plants such as aloe vera, horsetail, thistle, mugwort, yarrow, and comfrey. For FFJ (Fermented Fruit Juice) you can use tomatoes, berries, cantaloupe melons, apricots, and sweet peppers.  

Basically, FFJ or FPJ is made with fruits or plants respectively. This is one of the best ways to provide nutrients to your plants in a 100% organic and natural way. 

Now, let’s find out how you can make it to your home:

Step 1. Chop your plant in smaller pieces or peel and cube the fruits if you are opting fruit option. Don’t wash the plants or fruits if you are using them from your garden. As they have beneficial bacteria that enhance the fermentation process.

Step 2. Weigh your chopped plants or fruits. Then put them into a large glass jar or container. Then add an equal amount of brown sugar in that. After this, mash up the plant material with a large spoon or anything else. You have to mix until the sugar didn’t distribute all over the material.

Step 3. Cover the opening of the container with a piece of cheesecloth. You can also use an elastic band to tighten the grip. Carbon dioxide will easily escape through the small holes that are created by the fermentation process. Now, store the mixture in a cool and dark place for 7 to 14 days.

Step 4. After that, strain the mixture through a fine sieve and you can pour it into the bottles for storage. Further, keep them in your fridge until you use them.
