Compost Teas for Cannabis: The Ultimate Guide to Boosting Your Organic Grow
If you’re looking for a natural and effective way to give your organic cannabis grow a serious boost, look no further than compost teas. These nutrient-rich home brews are packed with beneficial microorganisms, vitamins, and minerals that can take your plants to the next level.
In this comprehensive guide, we’ll dive deep into the world of compost teas for cannabis. We’ll explore the benefits of using them, provide a step-by-step guide on how to brew your own and discuss the different types of teas.
What are Compost Teas?
Think of it like making a big batch of tea, but instead of using tea leaves, you’re using compost or worm poop. Compost teas are essentially homemade liquid fertilizers made by hanging a bag of compost in water similar to a tea bag. During this process, the beneficial microorganisms, nutrients, and other goodies in the compost are extracted into the water, creating a concentrated liquid that’s perfect for feeding your cannabis plants and is easily absorbed.
The Benefits of Using Compost Teas for Cannabis
- It enhances plant growth and vigor
- It improves soil structure and water retention
- It boosts plant immunity and disease resistance
- It increases nutrient availability and uptake
- It promotes the growth of beneficial microorganisms in the soil
- It provides a natural alternative to synthetic fertilizers
Compost teas are essentially a way to supercharge your soil and give your plants everything they need to thrive. By introducing a diverse array of beneficial microbes and nutrients, you’re creating a healthy, living soil that can support robust plant growth.
Different Types of Compost Teas:
Not all compost teas are created equal. In fact, there are two main types of compost teas: bacterial teas and fungal teas.
Bacterial teas are dominated by, you guessed it, bacteria. These teas are great for fast-growing annuals like cannabis, as the bacteria help to quickly break down nutrients and make them available to the plants.
Fungal teas, on the other hand, are dominated by beneficial fungi. These teas are better suited for perennial plants and trees, as the fungi help to create a more stable, long-term soil structure.
For cannabis, we recommend sticking with bacterial teas. These teas are easier to make and are more suitable for the rapid growth and nutrient demands of cannabis plants.
Equipment Needed for Brewing Bacterial Compost Teas
Can and should are two different things. You certainly can grow up to 10 or more plants per square meter, but tha
Before we get into the nitty-gritty of how to make compost teas, let’s go over the equipment you’ll need:
- A large bucket or container (20 liters or more)
- An aquarium air pump and airstone with a long tube
- A mesh bag or cheesecloth
- A stirring stick or wooden spoon
- A sugar source like unsulfured molasses (optional)
- High-quality compost or worm castings
Step-by-Step Guide to Brewing Compost Tea:
Once you have your equipment ready, it’s time to start brewing! Here’s a simple step-by-step guide to making your own compost tea:
- Fill your bucket with unchlorinated water. If you’re using tap water, let it sit out overnight to allow any chlorine to evaporate. Chlorine kills the microorganisms in tap water which is ok for humans to drink but bad for plants and making compost teas
- Add 1-2 cups of high-quality compost and/or worm castings to your mesh bag or cheesecloth. Tie it off and place it in the water.
- Add 1-2 tablespoons of unsulfured molasses to the water or some blended sugary fruit or even brown sugar. These sugars will feed the microbes and help them multiply.
- Place your air stone in the water and turn on your air pump. This will oxygenate the tea mix and keep the microbes happy and healthy.
- Agitate the bag and its contents properly for a minute or two to make sure all the solid materials are broken up and able to mix with the water. Try to place the bag directly above the bubbles of the air pump.
- Let your tea brew for 24-36 hours in a warm environment similar to your grow room, stirring and agitating occasionally. The tea should have a pleasant, earthy smell. If it smells foul or rotten, something went wrong and you should start over.
- After brewing, remove the compost bag and use the tea immediately. You can apply it as a soil drench or a foliar spray, diluting it 1:2 with water or more if needed.
And there you have it! With a little patience and the right ingredients, you can brew up a batch of nutrient-rich compost tea that your cannabis plants will love.
Compost Tea Tips and Tricks:
Before we wrap up, here are a few final tips to help you get the most out of your compost teas:
- Use high-quality ingredients. The better your compost and other additives, the better your tea will be.
- Don’t over-brew your tea. Anything longer than 36 hours can cause the microbes to start dying off.
- Apply your tea as soon as possible after brewing. The microbes are most active and beneficial when the tea is fresh.
- Experiment with different recipes and ratios to find what works best for your plants and growing conditions.
- Have fun and enjoy the process! Brewing compost teas can be a fun and rewarding way to connect with your plants and improve your organic growing skills.
