Medicine evolved using herbs. With the history of herbal remedies as a guide, many people choose this natural approach to medicine today. Cannabis is an herbal drug that can help various medical conditions, from joint pain to migraines.
However, cannabis must be grown carefully to create results. Hydroponics is a soil-less gardening method that can cultivate several plants.
The method allows growers to manage the nutrients, pH levels, and environment. You’ll need the following advice to maximize cannabis growth with hydroponics!
Evenly Distribute Light to All Plants
LED lights offer a full spectrum of light that mimics natural sunlight. However, these lights can facilitate photosynthesis only if all plants have proper exposure to light.
Uneven light distribution leads to varying growth rates among plants, resulting in an inconsistent harvest. Plants under well-distributed light receive an adequate amount of energy for photosynthesis and uniform growth.
Create Sufficient Airflow
Adequate airflow prevents mold and pest infestations and strengthens plant structures by stimulating stalk and stem growth. When several sources regulate temperature, control humidity, and replenish carbon dioxide in the growing environment, cannabis plants will thrive.
Exhaust fans function by pulling warm air out and drawing in fresh air. These are typically at the top of the grow space. They are effective for temperature regulation and maintaining constant air circulation.
Another option is an oscillating fan. The fans move back and forth to distribute air evenly throughout the grow room. They can help in preventing hotspots and ensuring all plants receive an equal amount of airflow.
The goal is to replicate the natural breeze that plants would experience outdoors. Implementing fans will create the airflow your plants need to encourage growth.
Add Dry or Liquid Nutrients As Needed
Supplying cannabis plants with the right balance of nutrients is vital for their growth. Magnesium contributes to photosynthesis, while potassium sufficiently distributes water to the leaves. If you ever witness one of the signs of nutrient deficiencies in plants, like curled or yellowed leaves, add the nutrients in dry or liquid form to promote healthy growth.
The roots readily absorb liquid nutrients, making them often favored for their convenience. However, they tend to be pricier and have a shorter shelf life.
Dry nutrients are cost-effective because they last longer and contain more nutrients per purchase, which is ideal for large-scale operations. They require more effort in preparation, with precise measurements and thorough mixing to ensure they dissolve completely in the water.
Regularly Monitor the pH of the Water
The pH level is a crucial factor to consider to maximize hydroponic cannabis cultivation. The pH level is a measure of acidity or alkalinity that influences nutrient absorption and overall plant health.
The ideal pH range is between 5.5 and 6.5. Monitor the pH level using a pH meter or test kit. If the pH level is too high or too low, the plants may exhibit signs of nutrient deficiency, even if nutrients are abundant in the system. This is because plants can absorb certain nutrients only within specific pH ranges.
Use pH up and down solutions sparingly to avoid drastic swings that stress the plants. Always dilute these solutions in water before adding them to the system and retest the pH after each adjustment.
As with any cultivation method, diligent care, regular monitoring, and a willingness to adapt your practices based on your plants’ needs will pave the way for a flourishing hydroponic cannabis garden.
