If you are a cannabis grower, it is safe to say that you want to produce the best cannabis. Therefore, professional cannabis fertilizer is essential to growing healthy and high-yielding cannabis, ensuring they can get enough nutrients they need to absorb.
What Nutrients Cannabis Need?
In order to make plants grow as healthy as possible. There are three major nutrients that are needed by plants: nitrogen(N), phosphorus(p), and potassium(K). And some other micronutrients and minerals.
These are usually found on cannabis fertilizer labels and are displayed in numerical order corresponding ratio to the nitrogen, phosphorus, and potassium content of the fertilizer. Let's understand the role of each nutrient to better understand the actual benefits of using weed fertilizer.
Cannabis has a relatively simple growth cycle, divided into three stages:
1. Seedling Stage: Cannabis seedlings are very fragile and easy to "burn" in nutrient-rich soil. Therefore, we do not recommend feeding during the seedling stage.
2. Vegetative Stage: The roots begin to develop and leaves begin to grow during this period. It is time to start feeding them the nutrient solution of your choice. High nitrogen, medium phosphorus, and high potash fertilizer are required in the nutritional stage.
3. Flower Stage: The levels of nitrogen, phosphorus, and potassium were different in the vegetative and flowering stages. So it is important to know that low nitrogen, high phosphorus, and high potassium are needed at the flowering stage.
Cannabis Fertilizer for Bloom
The flowering period is the most critical period of plant growth for cannabis growers and this period is about eight weeks.
There are five steps in the flowering period, including transition, primary buds development, buds growth, buds maturation, and harvest of buds.
During the process of flowering, if you want to obtain high-quality buds, you need to provide the right amount of nutrients to the plant.
Nitrogen(N), phosphorus(P), and potassium(K) are essential nutrients for the growth of cannabis. When weed begins to flowering, they must gradually increase the concentration of P and K, while greatly decreasing the concentration of N.
This is the reason why there are two kinds of special cannabis fertilizers for vegetative growth and flowering.
In addition, some "secondary" nutrients are also essential for weed like magnesium (Mg), calcium (Ca), and sulfur (S), but the using quantity is much smaller than NPK.
Some trace elements are also needed by cannabis to reach its full potential, such as copper (Cu), boron (B), zinc (Zn), chlorine (Cl), iron (Fe), manganese (Mn), and molybdenum (Mo). The amounts of these trace elements required by cannabis are exceedingly small and are often mixed into fertilizers or soil.
Seaweed Extract Effect for Cannabis
The health of the cannabis is a very important part of cannabis cultivation. This is why we need a great deal of consideration and research to understand the best nutrients to promote the health of crops. Especially there are many beneficial nutrients in the seaweed extract that can help your cannabis reach its optimal size and grow healthy.
Fresh seaweed contains calcium, magnesium, boron, sulfur, and an unlimited amount of macro and micronutrients absorbed from the ocean.
Besides, seaweed can help retain soil moisture, thus reducing watering cycles, while still encouraging beneficial bacteria that help plants break down organic matter and obtain essential nutrients.
It also produces certain compounds that act as a defense mechanism that is effective against fungi, bacteria, and viruses.
Applying seaweed fertilizer to plants can promote cannabis germination and at the same time regulate the pH of the soil. It also promotes the metabolism of cannabis by increasing trace elements in the soil, while improving the soil structure for easy access to nutrients and root growth.
Soil Amendments for Cannabis Growth
The best basis for cannabis cultivation is good soil and nutrients. The physical condition of the soil is the major factor that directly limits the health and vitality of cannabis. It is especially important for weeds when soil fertility influences weed yields. When the soil condition is poor, water intake, root development, and aeration are restricted.
When soil amendments are applied to the soil, it provides many benefits. The most common one is improve the soil structure which can increase the texture of the soil and keep it loose, so that cannabis absorbs more nutrients and water.
Common organic soil amendments for cannabis: Worm castings, Crustacean meal, Bat guano, Bone meal, Rock dust, Kelp meal, Compost, Mycorrhizal fungi, Trichoderma harzianum.
