Molasses Compost Tea for Cannabis

Molasses compost tea is an age old technique that provides abundant nutrients to plants at a very affordable cost. Gardeners have been using this tea to spray directly on growing plants leaves or to drench the soil before planting. Although its an old technique, the cannabis community has only recently heard about its amazing effects on marijuana.

What you need in a nutshell:

  • 10 litre container
  • Aquarium pump
  • A long stirring stick
  • Muslin or cheesecloth
  • 5 litres good-quality, well-aerated organic compost
  • 125 ml unsulphured organic organic molasses
  • 5 litres of water
  • Nowadays it is possible to buy pre mixed compost tea products that are very easy to prepare but doing so will be more costly and deprive you of the knowledge of doing it for yourself. Its not only rewarding to do it yourself but you can customize your mixes to your plants preferences accordingly.

Why is Molasses Compost Tea for Cannabis so Beneficial?

The most important aspect about adding a molasses based compost tea to your cannabis grow is the enrichment of the soil. Not only do you inject a great deal of micro and macro-organisms to the soil, but you also improve drainage, aeration and texture. But aside from that, the ‘soil food web’ which are comprised of beneficial bacteria, fungi and more microorganisms are strongly benefited so your plants become healthier and yield more produce.

You should never replace traditional soil fertilisers for compost tea but rest assured, applying this to your grow will be an excellent way to strengthen your ‘soil food web’ if applied as a soil drench. If used as a foliar feed (spraying on leaves) its micro nutrients will be easily absorbed by the plant to then be converted into food. Read more about feeding molasses to plants here.

So how do we it?

You’re going to require:

  • 5 litres of nice quality soil. It can be coco coir mixed with properly aerated compost soil. You may even purchase it from a shop or make it yourself. The only real difference is cost. It will be cheaper to make your own good quality soil than to buy it.
  • a 10 litre container
  • an aquarium pump with 1 or 2 airstones or bubblers
  • 125 ml of unsulphured organic molasses
  • 5 litres of water
  • a long stirring stick
  • cheesecloth or anything similar to sithe the liquid from solids

Method to the madness:

  1. Fill up the 10l container with the 5l of soil made from compost and coco coir, top up with the 5l of water
  2. Add the 125ml of molasses (if its colder, the microorganisms in the soil could  you might need more molasses to feed the microorganisms in the soil in order for them to properly reproduce)
  3. Thoroughly mix up the soil, molasses add water
  4. Put the aquarium pump in the container and turn it on to aerate water
  5. Leave to ferment for a couple of days, optionally wait 3.

Make sure to stir the mixture three times per day to completely combine the ingredients. After a few days has passed, around the 3rd day inspect the smell of the cannabis molasses compost tea. If it doesn’t do your nose any justice i.e. mixture smells of or too fermented, add more molasses, stir to combine and check the brew in another day. As a general rule of thumb don’t leave the mixture for more than 4 days.

When the cannabis molasses compost tea achieves a nice, aromatic musk like smell, it is a sign it is good to be strained through a cheesecloth or other textile based strainer. The liquid strained can then be finally used on your plants. Once you have strained the compost tea from the solids, use within 3 days as the tea will go off. If you wish to prolong the the expiry, add more molasses to the tea and turn on the water pump again to provide oxygen and nourishment to the beneficial bacteria in the tea. Remember this will only extend the life by only a few days, do not leave it longer than that!
