There is a great deal of debate over the ideal way to use molasses effectively. For those who are just learning how to grow weedadministering through watering may be the most successful. Others prefer to mix molasses in combination with a super soil recipe or regular veggies plant soil.
- 2 tablespoons of molasses per gallon of water
- 4 tablespoons of molasses per 1 gallon of water
How to grow weed with molasses
Growing marijuana using molasses in soil
You could ask around to find out your friends most commonly used methods, but there are so many ways to feed cannabis plants that the answers you will receive will be inconsistent. So much so that it might even feel a little overwhelming at first. Here, we will focus on using molasses as food for growing marijuana plants including how to use it, the benefits, and how it works.
The benefits of using molasses
Molasses typically comes in a jar and is a thick, viscous syrup that is extracted from raw sugar cane as it is refined into granulated and icing sugars. A lot of people know molasses to be a cooking ingredient that is often used to sweeten dishes, but the kind that is required for growing marijuana are organic. If you try to use an average bottle of molasses, it will contain hundreds of additives that might harm cannabis, so it is critical that garden use certified molasses be purchased for this task.
Use either the directions located on the product or the one provided below to combine the water and molasses. This solution should only be used from the flowering stage until two weeks before harvest.

There are also different types, or “grades”, of molasses, from lighter coloured molasses that is pure sugarcane syrup, to darker molasses and then blackstrap molasses which is denser and thicker than the other types. Blackstrap molasses has undergone multiple boiling and extraction processes, so that it has the highest concentration of vitamins, micro and macro elements. It is very rich in calcium, iron, magnesium, potassium and other valuable elements.
The risk for overfeeding with molasses is considerably lower than with mineral nutrients, but it is smart to observe your plants for any signs of stress or nutrient burn, in particular if you add molasses to an existing feeding regimen. If things look good, you can gradually increase your dosage if needed. You can add it to organic liquid fertilizers, such as compost teas. If you’re adding molasses to your existing feeding regimen, you should also keep an eye on your soil’s pH level, since any additional substance can affect it. Make sure you check your runoff pH frequently.
What makes molasses invaluable for growing cannabis isn’t just its benefits for healthy plant growth, but also the versatility in usage. You can use it like a regular nutrient that you add to your feeding schedule, you can make composts and compost teas, use it to prepare a particularly rich soil, or apply it as a foliar spray.
Molasses or black treacle, as it is called in the UK, is a highly viscous, dark substance that is made during refining of sugar. It is made by boiling down sugar cane or sugar beet juice into a thick syrup. Once sugar crystals are extracted, a syrup that remains is called molasses. Different types of molasses are available, they vary in sweetness and in the way they are extracted. Molasses made from sugar cane is often made into sweeteners or used as a flavouring for foods. Sugar beet molasses, on the other hand, has an unpleasant smell and is unpalatable, so it is normally used as an animal feed additive. Not all types of molasses are suitable for growing. Some molasses of low quality can contain undesired additives, such as preservatives and chemicals that you definitely don’t want in your garden. Make sure you look for organic molasses that is suitable for gardening.
This is not to say that these supplements wouldn’t get the job done. The advantage here is simply that molasses will cost a lot less than some fancy-brand cannabis supplements, yet will provide your plants with the same benefits. What’s more, it’s easy to buy molasses: you can get organic blackstrap molasses at most grocers and in many general stores. Also, some gardening stores stock molasses.
But the nutritional compounds in your soil, the chemicals, minerals and other inorganic substances are not all there is to make a good environment for your plants. Soil also contains beneficial microorganisms which live in it. These microorganisms are also playing a vital role in healthy growth of your plants.
A common problem with growing cannabis can be when salt from feeding mineral, non-organic nutrients builds up in the soil over time. The accumulated salt can at some point throw off the pH level in the soil, preventing the plants from taking in nutrients any longer—the dreaded nutrient lockout. Molasses works more indirectly, as compared to mineral nutrients where you simply add nutrients every time you feed your plants. This is why using molasses doesn’t come with the same risk of salt build-up.
How much molasses you should use, normally depends on the particular strain that you’re growing and its nutrient requirements. The right dosage can also depend on your plant’s age and may be different depending on environmental factors, such as temperatures and light intensity.
When you’re starting out feeding molasses, it is recommended that you start with lower dosages at first. A good starting point can be 4–5ml of molasses per litre of water. Later, when your plants are flowering, you can increase the dosage a bit, since your cannabis plant will need more potassium. Although you can use molasses during all stages of growth, including the vegetative phase, you will likely notice the most benefits during flowering.
