How Do I Use LED Grow Lights for Cannabis Cultivation at Home?

Recently, I bought an LED grow light for my cannabis plants. But I don’t know how to use it.

Seedling

Keep in mind that cannabis seedlings need less light because they are delicate. During this time, you should position your LEDs farther away and higher up to avoid drying up the soil due to too much light.

Since the precise distance relies on the wattage of your LED grow lights, it might be challenging to calculate. As a general rule, cannabis seedlings should be kept 24 to 36 inches away from your lights.

When your weed plants get bigger, you can encourage photosynthesis by applying more intense light. Just be careful.

Vegetative Phase

During this period of time, your weed plants will require more light for photosynthesis, so position your LEDs closer together. Your cannabis plants’ tops should be 12 to 24 inches away from the LEDs. If you are unable to adjust the height, you should change the brightness of the light.

Your marijuana plants will become less picky about light intensity as they become bigger. Blue lights are perfect for vegetable gardening to encourage robust leaves and stems.

Flowering Phase

Put your LED lights 16–36 inches below the canopy of your cannabis plants. Avoid putting your cannabis LED lights too close together as this will stunt the growth of your weed plants.

Red light is ideal for bud development and stem acceleration throughout the flowering period of your marijuana plants. They also aid in potency and resin production.

As your marijuana canopy grows, make sure you keep a close eye on the distance and move your LED lights away from it.
