Why compost tea?

Compost tea is an important part of growing cannabis. It helps to add nutrients and beneficial bacteria to the soil, which can help your plants grow better. Compost tea is also a great way to recycle your kitchen scraps and other organic matter.


Compost tea is a great way to give your cannabis plants a nutrient boost. It’s easy to make and can be used as a foliar spray or added to your soil.

Compost tea is made by steeping compost in water and then straining it. This process extracts nutrients, bacteria, and fungi from the compost, which are then available for your plants to use.

The benefits of compost tea include:

– Improved plant growth
– Increased nutrient uptake
– Enhanced disease resistance
– Improved structure and porosity of soil

To make compost tea, you will need:
– 1 gallon (4 L) of water
– 1 cup (250 mL) of compost
– A 5-gallon (19 L) bucket with a lid
– An air pump with tubing and an air stone


The main event in compost tea are the microorganisms. These are the good guys that will help your plant to grow big and strong. There are all sorts of different microorganisms living in compost, including bacteria, fungi, protozoa, and nematodes. All of these different critters play an important role in breaking down organic matter and making nutrients available to plants.

In recent years there has been a lot of excitement about the role of beneficial microbes in plant health. This is especially true in the cannabis world, where growers are always looking for ways to increase yields and potency. Many commercial compost teas on the market today contain a mix of different microbes that are tailored specifically for cannabis plants.

To make your own compost tea, you will need to start with some high-quality compost. This can be store-bought or homemade, but it should be free of any chemicals or pesticides. You will also need some kind of aeration system to oxygenate the water as the microbes grow. A simple air pump with an aquarium stone will do the trick. Finally, you will need a way to strain out the solids before applying the tea to your plants. A coffee filter or piece of cheesecloth placed over a bucket will work well for this purpose.

How to make compost tea

Compost tea is a great way to give your cannabis plants a nutrient boost. It is easy to make and can be made with things you probably have around the house. You will need a five-gallon bucket, some compost, a aerator, and some hose clamps.


To make compost tea, you will need:
-A 5-gallon bucket with lid
-An aquarium air pump
-Air stone
-Three feet of aquarium tubing
-Compost (preferably high quality, aerated, and alive with colonies of microorganisms)
-Worm castings (optional)

The process

When it comes to cannabis cultivation, there are many things you can do to “go organic.” This includes using all-natural products for your grow operation, such as organic compost tea.

Compost is a key ingredient in any organic gardening operation. It provides essential nutrients and beneficial microorganisms that help plants thrive. Compost tea is a liquid solution made by steeping compost in water. This “tea” can then be used as a fertilizer or soil amendment for your cannabis plants.

Making compost tea is simple, but there are a few things you need to know before you get started. Here’s a quick guide on how to make compost tea for cannabis plants.

1. Start with high-quality compost. If you’re not making your own compost, look for a quality product at your local garden center or nursery. Make sure the compost is free of chemicals, pesticides, and herbicides.

2. Steep 2-5 pounds of compost in five gallons of water for 24-48 hours. Use an aerated container, such as a five-gallon bucket with an air pump attached to it. This will help oxygenate the water and promote the growth of beneficial microorganisms in the compost tea.

3. After 24-48 hours, strain the compost from the water using a cheesecloth or similar material. Your finished compost tea is now ready to use!


To make compost tea, you’ll need a 5-gallon (19 L) bucket, an air pump and stone, some cheesecloth or a coffee filter, and a long-handled spoon. You can buy an air pump at any garden store; make sure to get one that’s rated for at least 5 gallons (19 L).

Fill your bucket about halfway with aged manure or compost. If you’re using fresh manure, mix it with an equal amount of water first. Otherwise, the fresh manure will release too much ammonia gas and harm the beneficial microbes in your tea.

Attach the air stone to the air pump and place it in the bucket. Turn on the air pump and let it run for about 30 minutes to saturate the water with oxygen.

After 30 minutes, turn off the air pump and cover the bucket with cheesecloth or a coffee filter. Let the mixture steep for 24 hours.

After 24 hours, remove the cheesecloth or coffee filter and stir the mixture well with a long-handled spoon. Scoop out about 1 gallon (3.8 L) of tea and use it to water your plants. Pour any leftover tea back into the bucket and keep it covered until you’re ready to use it again.

How to use compost tea

Compost tea is an excellent way to give your cannabis plants a boost of nutrients. It is easy to make and can be used to water your plants or as a foliar spray. You can also add compost tea to your soil to help improve the quality of your soil.

Foliar spraying

Foliar spraying with compost tea is an excellent way to introduce extra organic matter and beneficial microbes into your cannabis grow operation. In addition to providing your plants with a boost of nutrients, compost tea can help to fight off pests and diseases.

Making compost tea is a simple process that can be done with just a few supplies. You will need:

-A 5-gallon bucket
-An aquarium air pump
-An air stone
-A clean sock or some cheesecloth

To make your compost tea, start by adding two or three shovelfuls of compost to your bucket. Then, add water until the bucket is about three-quarters full. Next, attach your air stone to the aquarium pump and place it in the bucket. Turn on the pump and let it run for about 24 hours.

After 24 hours, turn off the pump and let the tea settle for a few minutes. Then, use your sock or cheesecloth to strain out any solid pieces of compost. Your tea is now ready to use!

Watering plants

Compost tea is a great way to give your plants a boost of nutrients and beneficial microorganisms. It’s easy to make, and all you need is some compost, water, and a few other simple ingredients.

Here’s a basic recipe for compost tea:

1. Fill a 5-gallon bucket with water and let it sit for 24 hours to allow the chlorine to evaporate.
2. Add 1 cup of compost to the bucket.
3. Stir in 1 teaspoon of molasses or honey.
4. Place the bucket in a sunny spot and let it brew for 3-5 days, stirring occasionally.
5. When the tea is ready, strain it through a cheesecloth or coffee filter to remove any solids.
6. Pour the tea into a watering can or spray bottle and apply it to your plants’ leaves, taking care to avoid getting any on the flowers or buds if you’re growing cannabis.
7. You can store unused tea in the fridge for up to 2 weeks.

Brewing compost tea is a simple way to give your plants a nutrient boost, and it’s also a great way to use up any extra compost you have on hand. Be sure to follow the recipe closely, as too much compost can actually harm your plants instead of helping them


When making compost tea, the goal is to create a brew that is teeming with nutrients and beneficial microbes that will help your plants grow healthy and strong. There are a few things to keep in mind when making your compost tea. First, you’ll need to choose the right kind of compost. Second, you’ll need to aerate the compost tea properly. And third, you’ll need to make sure the tea is the right temperature. Let’s get started!


You can make a large batch of compost tea and then store it in the refrigerator for up to two weeks. Be sure to use an airtight container so that your tea doesn’t go bad. When you’re ready to use it, simply mix it with water at a 1:1 ratio and apply it to your plants.

Tea bags

Removing the tea bags after steeping is important, as you don’t want the tannins from the tea leaching into your final product. Tannins can be beneficial in small amounts, but too much can lead to nutrient deficiencies and stunted growth.
