Growers cultivate a variety of plants in their grow rooms, and they must get all equipment needed for the rooms. Grow lights are often a challenge for growers since the lights emit differing levels of heat and light. When setting up LED grow lights, the grower must follow tips to avoid crop damage and significant losses.

1. Select Grow LED Lights With A Wider Beam Spread

Grow lights with wider beam spreads farther into the grow room. This could provide the grower with more coverage and maximize the light in the grow room. By maximizing the lighting in the grow room, the plants can receive adequate lighting with fewer grow lights, and the growers can save money on these expenses. The grower must review the amount of light flowing into the space from the lights when setting up the grow room. Growers can check out more at to learn about wide-beam grow lights.

2. Do Not Mount the LED Light Too High for the Plants

The height at which the grow lights are installed in the room dictates how much light and heat the plants receive. If the lights are installed too high, the light and heat will not reach the plants appropriately. By measuring the height before installing the lights, the grower can ensure they aren't too far away from the plants and will provide the most benefits. The recommendations are to hang the lights no less than 12 inches from the plants and no more than 15 inches away.

3. Uses Timers for the LED Grow Lights

Grow lights provide adequate light for the plants, but some plants need varying amounts of light. With timers, the grower can set the grow lights to operate for a certain amount of time. They can set the timers to shut down after the time limit and restart later. Plants such as cannabis require 12 hours of sunlight and 12 hours of complete darkness. A timer for the grow lights could help growers maintain the appropriate amount of light and darkness for their crops.

4. Monitor the Temperature in the Grow Room

The temperature in the grow room is also critical for growing the crops. The grower must adjust their grow lights to maintain the correct temperature throughout the grow room. Growers that are growing cannabis crops must keep the grow room at 75 degrees. They need to set up a barometer to gauge the room temperature and adjust the lights according to the temperature readings.

5. Fluorescent or LED Bulbs

According to recent studies, the LED bulbs may cost more at first, but they are more energy-efficient and last far longer than the fluorescent bulbs. Growers could get more financial benefits by choosing LED instead. They can also decrease the temperature in the room, and the LED bulbs do not contain mercury. Overall, the LEDs may have a higher upfront investment, but the grower saves money over time and maintains a consistent temperature in their grow space.

Growers can use LED grow lights and maximize their benefits. The lights make it easier to control the temperature in the grow room and distribute adequate light. The bulbs last longer than other choices including fluorescent lighting. Growers use timers with the LED lights to control the light and give the plants the right conditions to thrive. By creating the best grow room settings, growers can maximize their yield and increase their earning potential significantly.
