Molasses is a thick, viscous syrup that is boiled down from either sugar cane or sugar beet juice. It has been used as a sweetener and cooking ingredient for many centuries. Molasses has a strong, distinct flavor that is both rich and sweet.
Molasses contains beneficial nutrients like minerals and carbohydrates that are essential for the healthy growth of cannabis plants. It is a source of sucrose, which is the primary energy source for marijuana plant metabolism. The minerals in molasses, including iron, magnesium, and calcium, improve the overall health of the weed plant.
The Importance of Molasses in Cannabis Growth
As cannabis grows into its life cycle, the plant requires essential nutrients for healthy growth. Molasses has become increasingly popular among cannabis growers as a source of organic nutrients that help in the cultivation process. Being a byproduct of sugar cane or sugar beet juice, blackstrap molasses is a rich source of carbohydrates, minerals, and beneficial microbes that can help promote plant health.
When added to the soil in a vegetative stage, blackstrap molasses provides the plant with essential nutrients in a form that is easy for it to absorb. The high mineral content in molasses makes it an excellent supplement to chemical nutrients, which can sometimes cause nutrient lockout and nutrient deficiencies when used alone. Adding it to compost teas or a foliar spray is also a great way to introduce beneficial bacteria into the soil, which can help support soil microbes and promote healthy plants.
One of the lesser-known benefits of using blackstrap molasses in cannabis growth is its pest resistance properties. The sulfur dioxide present in molasses acts as a natural pesticide and can help protect the plant from pests or insects that would otherwise cause damage. This pest resistance makes blackstrap molasses an excellent choice for outdoor growers who want to avoid using harmful chemicals to protect their crop.
What Type of Molasses Should You Use for Cannabis?
When it comes to growing cannabis, molasses can be a valuable addition to your gardening routine. Molasses is a natural source of carbohydrates and essential nutrients that can help promote healthy plant growth. However, not all types of molasses are suitable for cannabis plants.
There are different types of molasses available, including types made from sugar beets or sugar cane. Molasses can be light or dark in color and can be sold in either liquid or dry form. It is important to use the right type of molasses when growing cannabis to ensure optimal plant health.
Sulfur-infused molasses is a type of molasses that contains sulfur dioxide. Although sulfur can be beneficial for plants in small doses, it can work against the beneficial microbes we are trying to foster in our soil. Sulfur dioxide can harm the soil microbes that are essential for plant growth, making it best to avoid sulfur-infused molasses when growing cannabis.
Unsulfured molasses is a better option for cannabis growers. As the name suggests, unsulfured molasses is processed without the addition of sulfur dioxide. This makes it better suited for promoting the growth of beneficial microbes in the soil, boosting plant health.

Healthy Plants and Increased Yields
Molasses is a sticky, sweet byproduct of sugar production that holds numerous benefits for cannabis growers. Using a few tablespoons of molasses per gallon of lukewarm water can strengthen plant health throughout the life cycle, leading to healthier, more robust plants and increased yields.
When molasses is added to soil or compost teas, it serves as a source of beneficial nutrients such as magnesium, calcium, and iron, which are essential for healthy growth. Molasses contains sugar beet juice or sugar cane, both known for their high sugar content, along with minerals and carbohydrates that boost microbial activity and overall plant health.
Molasses is particularly useful during the flowering stage, where it helps to prevent nutrient deficiencies and heat stress. By adding molasses to the soil, you build a healthy foundation for roots and soil microbes that support healthy growth. During the flowering stage, cannabis plants require a higher nutrient uptake, and consistent use of molasses can help to maintain nutrient availability and prevent a nutrient lockout.
Beneficial Microbes and Compost Teas
Growing cannabis is an exciting and rewarding experience for any cultivator. To achieve the best results, it’s essential to have a healthy root system, rich soil, and an optimal environment in which plants can flourish. One of the key ways to achieve this is by using beneficial microbes and compost teas in the cultivation process.
Beneficial microbes are essential for the enrichment of the soil, which in turn helps promote a healthy root system. When the soil is healthy, it creates an environment that is conducive to growing bigger and stronger plants with better yields. It’s important to note that not all microbes are beneficial. But when you introduce the right kind of microbes into the soil, they can provide a range of benefits, including improved nutrient availability, disease suppression, and the breakdown of organic matter.
Compost teas are a simple and effective way to feed microbes to your plants. Compost teas are created by brewing compost in water, using anywhere from a few tablespoons to several cups of compost per gallon of water. The compost tea is then used as a foliar spray or added to the soil, enriching it with the beneficial microbes needed for healthy growth.
How To Use Molasses To Grow Cannabis
Molasses is a natural source of carbohydrates and essential nutrients that can be used to promote healthy growth and plant health in cannabis. There are different types of molasses, including light molasses, dark molasses, unsulphured molasses, and blackstrap molasses, each with varying mineral content.
Amount of Molasses Per Gallon of Water
Molasses has become a popular additive in cannabis growing because of its many benefits to plant health. And one commonly asked question is how much molasses should be added per gallon of water for optimal growth.
Firstly, during the vegetative stage, it is recommended to add 1/2 tablespoon of unsulphured molasses to a gallon of lukewarm water. This will supply the plant with essential nutrients and carbohydrates that are necessary for healthy growth.
During the flowering stage, the amount of molasses needed varies. Some cannabis growers have reported using between 1 and 4 tablespoons of molasses per gallon of water. It is crucial to note that too much molasses can lead to nutrient burn, which is damaging to the plant. Therefore, it is essential to keep a close eye on the plant’s response to the molasses and adjust the amounts accordingly.
The type of molasses used also plays a significant role in how much to add. Light molasses contains less mineral content, while dark molasses contains higher levels of minerals such as calcium, iron, and magnesium. Growers should experiment with different types of molasses to see which works best for their plants’ needs.
Foliar Spray
Foliar spray with molasses is an effective way to deliver nutrients and beneficial microbes to the plant. Foliar feeding helps with nutrient absorption and provides a natural pesticide that improves plant health and resistance to pests and diseases. Using molasses as a foliar spray requires some preparation and attention to avoid damaging the leaves.
To prepare the solution, mix one teaspoon of unsulphured blackstrap molasses per gallon of lukewarm water. Unsulphured molasses is preferred as it does not contain sulfur dioxide, a chemical that can harm beneficial bacteria and soil microbes. Transfer the solution into a spray bottle, and spray it liberally over and under the leaves, making sure to cover all the foliage and avoid drenching the soil.
When To Stop The Use Of Molasses On Cannabis
Excessive use of molasses can also lead to nutrient burn if overfed, resulting in stunted growth and damage to the plant.
To avoid nutrient burn, it’s essential to know when to stop using molasses on cannabis plants. As a general rule of thumb, it’s best to stop using molasses 2-3 weeks prior to harvesting the cannabis plant. This allows the plant to use up any excess nutrients before being harvested, resulting in a better-tasting and higher-quality yield.
Additionally, it’s crucial to pay close attention to the plant’s foliage. If a sign of nutrient burn appears, stop using molasses right away until the issue gets resolved. Signs of nutrient burn include brownish edges on leaves and curling of the foliage. If not addressed promptly, the nutrient burn can cause irreparable damage to the plant and affect the overall yield.
It’s also worth noting that molasses should not be used as a foliar spray during the flowering stage or past the first 3 or 4 weeks after flowering. This is because molasses attracts beneficial bacteria and microbes that could be harmful to the flowering stage. It’s best to stick to using molasses in the vegetative stage of the plant’s life cycle when it can benefit from the additional nutrients.
Final Thoughts
Molasses is an excellent source of essential nutrients and minerals for cannabis plants that promote healthy growth and increased yields. The benefits of using molasses are numerous, including increased nutrient availability, improved plant health, and enhanced flavor and aroma.
