Led Grow Light Distance Chart

A general principle for placing led grow light is 18 inches to 42 inches above the canopy of your plants but the accurate distance is determined by the type of led light wattage it uses and the growth stages of plants along with their types.

The led grow light must be used properly for optimum growth and yield. Similarly incorrect light placement will also not allow plants to grow to their full potential. For a 900 1000w led grow light the distance from the top of the cannabis plant during the vegetative phase should be 36 to 42 inches while the distance during the flowering phase should be 18 to 24 inches. If you do not provide enough light your plants will not grow to their full potential.

Once the roots establish and sprouting begins you can reduce the distance between the lights and the plants. Some growers make the mistake of intensifying the light to promote faster growth but this is not the best way to go with seedlings. Locate your led grow lights at the furthest distance from the seedlings 36 this keeps heat and light intensity levels lower and helps prevent seedlings from drying out.
