Understanding Light Schedules in Cannabis Hydroponics

Cannabis growth relies heavily on the right light schedule, and hydroponic systems offer precise control. Here's a breakdown to help you find the best light schedule for your setup.

Cannabis Hydroponics Yield Per Plant

1. Basic Principles

In hydroponics, light is the primary factor that controls plant growth. Typically, cannabis plants need a light-on, dark-off cycle. However, the specifics depend on the stage of growth.

2. Vegetative Stage

The vegetative stage requires 18-20 hours of light per day. This promotes healthy growth, ensuring the plant gets sufficient energy from light. LED and high-intensity discharge (HID) lights are efficient for this phase.

3. Flowering Stage

The flowering stage, crucial for producing buds, requires a shorter light cycle of 12 hours on and 12 hours off. This stimulates flowering and the development of potent trichomes.

4. Transition

To switch from vegetative to flowering, reduce the light cycle gradually. A week before transitioning, decrease to 14-16 hours of light.

Monitoring and Adjustments

Keep a close eye on your plants' responses. If they're not growing as expected, consider adjusting the light intensity or duration. Hydration levels also play a critical role.
