How Does Hydroponics Work?

Hydroponics works by delivering a nutrient-rich water solution directly to the plant's roots, bypassing the need for soil. The system consists of several components, including a reservoir to hold the nutrient solution, a pump to circulate the solution, and a growing medium to support the plants. The growing medium, such as coconut coir or clay pellets, provides stability for the plants without interfering with nutrient uptake.

The nutrient solution is carefully balanced to provide all essential macro and micronutrients required for plant growth. This solution is continuously monitored and adjusted to maintain optimal pH and nutrient levels. The plants absorb the nutrients through their roots, which are submerged in or exposed to the solution, allowing for efficient nutrient uptake.

Lighting is a crucial aspect of hydroponic systems, particularly for cannabis cultivation. Grow lights, such as LED or HID lights, mimic natural sunlight, providing the energy needed for photosynthesis. The duration and intensity of light exposure are controlled to replicate the plant's natural growth cycle, from seedling to flowering.
