LED Indoor Grow Lights – Which factors should I consider when setting up my grow lights?

Watts per plant for growing with LEDs

While LED lights don’t produce as much heat as normal lights, you still have to determine the right height of your light to not burn your plants. Different power ratings (watts) will perform best at different distances.

When you have a lower-powered light, like a 250 watt led grow light you should keep it between 30 – 60 cmabove the top of the canopy. Medium-range lights -between 600 and 900 watt- should be kept 35 – 75 cmfrom the top of your plants. Last, but not least, high-powered lights, such as 1500, 2000 or 3000 watt Led Grow Lights, should be raised 60 – 90 cm from the top of your canopy. When in doubt, further away would be the best rule to follow.

1500W + | 60 – 90 centimetres

Light Schedule for Cannabis Growth Stages
What do you need to know about the light schedule when using your LED lights in the vegetative and flowering stages of the growing process?

These light patterns mimic seasons which means that you can control when the flowering stage should start. Your cannabis plants won’t start flowering until they receive 12 hours of darkness each day.

This means they will continue staying in the vegetative stage until you add darkness to the grow space. You can keep your plants in the vegetative stage forever, as long as they will get more than 13 hours of light every day.

In the vegetative stage:
18 hours of light (some growers do 24 hours)
6 hours of dark

These are more commonly referred to as 18/6 schedule. Some growers decide to give their plants 24 hours of light a day, because a lot of light means they will reach their maximum potential quite fast.

During the flowering stage:
12 hours of light
12 hours of dark

The flowering stage are referred to as 12/12 light schedule.
