Buying Guide Questions


There are a couple of things you need to consider before choosing the best LED to grow light:

Brand, Budgeting, and Pricing

This would be critical as higher-quality lights normally show the best effects. If you’re a novice, you’ll probably want to start with a lower-priced alternative to get your feet wet. If you’re more seasoned, it never hurts to go for a higher-priced premium alternative. Besides, the name and the efficiency of the light are also significant. A strong brand of raving consumer feedback is almost always a sure thing.

Electrical Usage

Your LED lights would also require longevity and high electrical efficiency. A decent LED light should be in service for at least 10-12 hours a day. If you’re looking for a decent LED lamp, you’ll need to completely consider the overall production (1000w, 400w, 300w, etc.). The higher you go, the more efficient and the more likely it is to lead to far less electrical use (and more cost-effective for you).


You definitely ought to ensure that you know how much room you want to occupy with your LED lamps. Each light has the maximum area it can occupy, and it would be necessary to consider the dimensions of your rising space down to the centimeter. If you don’t know what it is right now, you should find out. When that is done, make sure you read reviews and suggestions from others on the real room that LED light can occupy.


A full spectrum LED rising light is going a long way to help your plant grow. You’ll need red & blue spectrum, and infrared and ultraviolet spectrum depending on the level. It is necessary to provide a powerful light with various energies to achieve maximum development. Full-spectrum yields are a little newer to the market, but they make strides to every decent grower catalog. They operate cool and do not need extra fans, they cost less over time due to electrical savings, and their reliability is second to none. It is strongly recommended that you buy a full spectrum LED rising light. Many LED lights have a variety of colors to be discharged.

Light Control

Depending on the stage, you’re going to want to make sure your plants get the right amount of lighting (down to the exact hour). Below you can observe the procedure overview for growing LED lights:

16 hours on, 8 hours off is required for the Seedling Phase

18 hours on, 6 hours off is required for the Vegetative Phase

12 hours on, 12 hours off is required for the Flowering Phase

It is highly critical that the light cycles are observed to the tee since they will severely alter the plants’ growth and potency.

How many plants can I grow with 1200w LED?

If they were in one gallon of jugs, you might put 16-18 plants under it. You’d get about 1/2 oz, dried and healed, out of an herb. Or, under the same light, you might grow one big bush of a plant. Anyway, you’d always end up with almost the same volume of bud.

How many plants can a 1000w LED light to grow?

It depends on the scale of the growing area and how big you grow the plants. While growing cannabis, a reasonable rule of thumb would be to use a minimum of 50 watts of light per square foot of growing area. We want to flood our plants with light (food) to have a lot of energy to develop big productive buds. Thus, we need to measure the square footage (length x width) of our growing space. We can then multiply this amount by 50w to give us the rough wattage of light we need. However, typically, you would be able to grow 1 – 20 plants under a 1000w grow LED light.

Is the best wattage for LED grow lights?

Plants, and particularly cannabis, require the most illumination during the flowering period, so we’ll use that as an approximation of how much area needs to be covered. The regular LED growing light must use more than 32 watts per square foot of growing area, but with optimum performance of more than 50 watts, up to 80 watts.

Can police detect LED grow lights?

In this respect, can police helicopters spot LED lights? Police I.R. helicopters could see the energy pour out like a waterfall. Helicopters can’t see through the walls, and they can’t see the rising stars. They can see just the heat on the exterior of the house.

Can you have too much light in a grow room?

While too much light can affect plant growth, it is also a reasonably easy problem to solve. There are a few different ways to repair a too-bright greenhouse. Distance is critical when it comes to illumination. Plant burning also happens as plants grow too close to the primary source of light and heat.


Finally, growing cannabis indoor requires a specific form of the indoor LED light. If you’re trying to grow some of these kinds of indoor plants, you need to learn many different kinds of LED growing lamps. They come with a range of bandwidth, quality, coverage areas, and cooling systems. The lumens and strength of these 1,200 watt LEDs yield differing intensities and energy efficiency. They come with a guarantee, so you can have them reviewed if there’s a problem. We listed some of the best 1,200w LEDs on the market. So, if you’ve read this post, we are damn sure that one of them can be your preference.
