However, even with several States and Countries adopting to the legalization of marijuana, this trend is not changing as farmers figured out that by planting indoors they can better control the planting environment leading to a good harvest.

One of the significant components that need control is the type and amount of light that the plants receive. Technology has not been shy in this field as advancements have seen indoor growers shifting from traditional HID and CMH Grow lights to new LEDs in their search for a cost-friendly alternative.

The metallic shelf is an essential piece of your grow room. It is where you will get to place your seedlings and watch them grow. You should assemble the shelving units and place it in the middle of the grow room to give you access from all the sides.

When using a fluorescent lamp, you should set up one warm and one cool bulb in one lighting fixtures and hang it along the lengths of the shelves. Ensure that all the shelves have light bulbs that alternate from warm to cool and are parallel to each other.


The S-hooks will help you to attach the lights on the shelf. You can use an adjustable chain link to give you control over the distance you want the light to be above your plants.

When using an LED strip light, you can tie one strip per shelf. However, what matters the most is the distance away from the plants. When planting seedlings, you can place them 24 to 28 inches above, and 12 to 18 inches above if the plants are mature and in their flowering or fruiting stage.

  1. Plugging the Lights

Before you connect the lights to the mains socket or extension cable, you should plug its cable to the surge protector, then to the power outlet. You can use the zip ties to bind up any excess cable lines to make the room look neat.

You can program a timer and set the hours you want the lights to be on every day. Finally, you can turn the entire lighting system on and watch your plants grow and thrive.
