Rice hulls are a popular growing medium for hydroponic gardens. They are economical, environmentally friendly, and provide plants with many nutrients essential for growth. They are a great growing medium because they are lightweight, sterile, and have a large surface area that allows plenty of oxygenation and drainage.
Rice hulls can be transformed into carbonized rice hulls. Do you know it?
This step-by-step guide will show you how to make carbonized rice hulls for hydroponics using a simple carbonization process and its useful details.
Let’s get started!
What is the difference between the Rice hull and Carbonized rice hull?
Carbonized rice hulls are made from Rice hulls that have been carbonized. This process changes the physical and chemical properties of the rice hull, making it a great growing medium for hydroponics. This is a useful addition to your garden, and it can also serve as mulch for your plants.
How to make carbonized rice hulls for hydroponics?
It is a simple process that can do in our home explained step by step below. You can carbonize rice hulls without using an oven by using a charcoal stove.
- Set the charcoal stove or oven to medium-high heat. For around 5kg of rice hulls, need approximately 10-15 small pieces of charcoal to heat. You can use an electric smoker too.
- Spread the rice hulls as a single layer on the cooking grate or baking tray.
- Heat the rice hulls for two hours or until they are light brown in color. Don’t heat it until it becomes ashes.
- Remove from the charcoal stove, smoker, or oven and let cool.
- Store the carbonized rice hulls in a container until ready to use.

That’s it! Enjoy! You now have carbonized rice hulls that can be used as a growing medium for hydroponics.
What are the properties and applications of carbonized rice hulls?
Carbonized rice hulls’ physical and chemical properties make them a great growing medium for hydroponics.
Some of the key properties & benefits of carbonized rice hulls include:
- Increased porosity
- Higher water retention
- Better water drainage
- Sterility – helps to prevent the spread of disease and pests.
- Provide good aeration
- Resistance to decay
- pH neutral
- It absorbs foul odors in the air via its activated carbon, which cleanses and deodorizes bad air.
These properties and benefits make carbonized rice hulls an ideal growing medium for hydroponics. Give it a try!
Carbonized rice hulls have a variety of applications, including:
- Sustainable growing medium in Hydroponics, Aquaponics, Vermiculture, Agriculture, Horticulture
- Good organic fertilizer.
- It can be used as mulch
- Great soil conditioner
- It helps refill the nutrients
If you want to use this carbonized rice hull as a fertilizer for your soil-based plants, apply it once every 20 days or twice each month.
This also can be used with other growing mediums by applying the correct ratio with the carbonized rice hulls.
What are the nutrients in carbonized rice hulls?
The nutrients in carbonized rice hulls vary depending on the carbonization process used.
There are two types of carbonization processes to make carbonized rice hulls, an oven carbonization process and a charcoal stove carbonization process.
The nutrients in carbonized rice hulls made by the oven are carbon, hydrogen, and oxygen.
The nutrients in carbonized rice hulls made by the charcoal stove are carbon, hydrogen, nitrogen, and oxygen.
However, carbonized rice hulls typically contain high levels of macronutrients such as potassium(K), phosphorus(P), nitrogen(N), magnesium(M), and calcium(Ca). This makes them a great growing medium for hydroponics.
It also contains micronutrients making carbonized rice hulls are a great growing medium for hydroponics!
Are carbonized rice hulls a good growing medium for hydroponics?
Yes, carbonized rice hulls are an excellent growing medium for hydroponics because of their macronutrient and micronutrient content. The carbonization process makes the C to N ratio very good, which is essential for plant growth. Additionally, carbonized rice hulls’ properties make them an ideal growing medium for hydroponics.
Consequently, carbonized rice hulls should be used as a growing medium in hydroponics.
