Before building a compost tea brewer, you need to consider the size of your cannabis garden. Most homegrows use 5-gallon buckets. On the outside of the bucket, you’ll need to have an air pump connected to an aerator device at the bottom. The aerator and air pump will oxygenate water so microorganisms can breathe.
There are some complications in working with organic fertilizers. The main issue is if your weed plants have a nutrient deficiency, it takes longer for a plant to absorb organic powder nutrients, which can increase the damage to plants. Liquid nutrients act much quicker. Other disadvantages:
However, the benefits of compost tea are debated in the agricultural world. Many gardeners report quality results when using it, while others see no more benefit than applying straight compost. The uncertainty lies in whether or not growing and developing populations of microorganisms in the tea can actually benefit plants and prevent disease.

Potassium also triggers the production of ATP, which works to store energy produced in photosynthesis by creating glucose. This glucose is then used as energy for the plant as it grows. Without sufficient potassium, you will see weak plants starved for energy that appear burnt because they are unable to successfully regulate the exchange of CO2, H2O, and oxygen.
Nitrogen is also necessary to create nucleic acid, an essential ingredient in DNA or RNA, and without it, cells won’t be able to grow and multiply.
Here are five key compost tea ingredients recommended by the Beneficial Living Center located in Arcata, California, to create a successful tea that will work best for your cannabis.
Products are also generally divided into “grow” solutions, high in nitrogen needed for vegetative growth, and “bloom” solutions, high in phosphorus for flower development. You can stick to these general terms if you don’t want to get bogged down with numbers.
The key part in all of this is the “peak enzymatic activity”. Basically, enzymes help plants do everything from photosynthesize, to more readily take up and make use of nutrients and minerals! The use of malted barley provides a lot of the same benefits as sprouted seed teas, so we’ll talk more about the role of enzymes in that below. Also like sprouted seed teas, you really can’t go overboard with malted barley! It is very mild and will not burn your plants.
“The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes. Without enzymes, many of these reactions would not take place. Enzymes catalyze all aspects of cell metabolism. This includes the digestion of food, in which large nutrient molecules (such as proteins, carbohydrates, and fats) are broken down into smaller molecules; the conservation and transformation of chemical energy; and the construction of cellular macro-molecules from smaller precursors.

How to Make Malted Barley Top-Dressing
The process of making sprouted alfalfa seed tea. It is all ready to water with now! The same process is followed for any type of seed, be it barley, corn, or mung bean.
It is best to mulch the top of your grow bag or soil surface area to maintain a healthy soil. We love using biodynamic accumulators that not only provide moisture retention, but will later break down into more nutrients and energy for the cannabis! These plants are especially good at taking up and storing nutrients in their leaves. Some examples of biodynamic accumulators are borage, comfrey, yarrow, horsetail, and dandelion greens. Fava bean greens are also excellent for green mulching, since they’re nitrogen fixers! If you don’t have access to these types of plants, straw or hay will work as mulch – but will not feed cannabis as much as the others. We grow all of these with mulching in mind!
What is malted barley, and why is it so special? Yes, this is the same stuff that is used to brew beer! Therefore, you can usually obtain organic malted barley from a local homebrew store, or buy it online. In this context, “malted” is used to describe barley grains that have been germinated. Under controlled conditions and temperatures, the wet grains are allowed to sprout… just a little bit. The process is halted when they reach peak enzymatic activity, which makes them ideal for future fermentation – or use in the garden!
