This LED system contains 5000K white, 3000K warm white, 660nm deep red, and 730nm IR light. This full spectrum will help your cannabis plant grow healthy and fast in all stages of its growth.

How to figure out the best distance to place your led grow light from your plants?

On the other hand, if it feels too much heat, adjust the distance accordingly. Once you feel comfortable, your plants will be comfortable as well.

This LED system will ensure safety for plants as well as for users. And you know, too many electrical appliances in the house will lead to some risks that you cannot predict.

The growing prominence of LED grow lights in the cannabis community is undeniable. So we have put together a few tips for anyone wanting to give them a go.

When you flower indoors on a 12-12 schedule, it is important that the 12 hours of darkness are not interrupted. So make sure that your tent or greenhouse doesn’t have any light coming in from outside. This would otherwise revert your flowering plant back to veg or potentially cause other issues such as hermaphroditism.

WHAT TO LOOK FOR WHEN CHOOSING AN LED GROW LIGHT

As we touched on earlier, many types of LEDs have a fixed light spectrum that works for both the vegetative (growing) and flowering phases of cannabis. This way, you can just use the same light throughout your entire grow from seed until harvest.

Set your light to 18 hours per day and 6 hours of darkness. Some growers choose to grow with 20–24 hours of light to maximise vegetative growth.

The drawback can be that a quality grow light with COB LEDs is quite expensive compared to cheaper purple lights. Some grow light manufacturers combine several COB LEDs into one fixture, often equipping them with lenses and reflectors. There are also lights available that are comprised of only one single COB. These single-COB fixtures can be a good choice for larger growing spaces, as you can space a number of them evenly for light distribution across the entire area. Most growers use COB LEDs with a light spectrum that works both for vegging and flowering, but you can also find those with a spectrum (“colour temperature”) tuned specifically to vegging or flowering.

Unlike with MH/HPS/LEC grow lights, there is no “standard” distance to keep each LED grow light and it’s hard to summarize with a quick chart like the others. The distance needed between an LED and the top of the plants varies quite a bit from model to model and from manufacturer to manufacturer. Many things can affect the optimal distance from plants, including the individual size of each LED bulb and the way the manufacturer used lenses to reflect light downwards at your plants.

Regardless of the name, LEC grow lights are basically a hybrid between Metal Halide and HPS grow lights. It is a type of Metal Halide bulb that is constructed with ceramic like an HPS. As a result, LEC grow lights last longer and are 10-20% more electrically efficient than MH lights. They also produce relatively high levels of UV rays, which may contribute to increased trichome development on cannabis buds, and can potentially make buds more potent.

In general, MH bulbs need to be replaced about once a year (every 2-3 grows), while HPS grow lights last a bit longer, up to 2 years (every 4-5 grows). Older HID bulbs give off less light and more heat, so in addition to keeping the right distance, make sure you’re aware of the age of your bulbs. To maximize the light to my plants in the flowering stage, I personally replace HPS bulbs every 3rd grow, but that’s a bit excessive.
