During the cloning and seedling stage, a plants entire life is shaped. Grow lights are one of the most important aspects of your grow room, and thus growers should ensure plants are being given ideal lighting during this early phase. Serious growers generally utilize a separate lighting system for cloning, vegetating, and flowering, to ensure optimal lighting conditions for each phase.
How many hours of lights do clones and seeds need?
Some growers insist on implementing a 24-hour light cycle, as this ensures a consistent temperature in the cloning machine. Other gardeners will opt for a short dark period, giving plants 18 hours of light. Regardless, it is imperative that clones and seedlings are given high quality light.
Most growers utilize fluorescent lights in the initial stage of a plant’s life, because they are bright, efficient, and can easily be mounted to distribute light evenly. A couple of 2-ft T5 tubes can cover a single propagation tray without burning or drying out the plants. LED and HID lights also work, but it is important to ensure they are not too close to the young plants or seedlings, as new plants are very sensitive.
The better lighting conditions you provide for clones or seedlings, the sooner they can be transplanted and moved into the vegetative stage. Grow light systems can be complex, and so if you have any questions reach out to our experienced growers at 888-815-9763 and let us help you through the process!
