Quick Answer: How far away should LED light be from seedlings?

Can seedlings go under LED?

Your seedlings need plenty of energy but won’t be able to get that if you place them beside your windows. Artificial lights are the best option for indoor seed starting. You want them to flourish after they start germinating, then you need to place them under LED or fluorescent lights.

Should seedlings get 24 hours of LED light?

A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. It’s believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.

Do seedlings need red or blue light?

Light Color

Red light stimulates vegetative growth and flowering (but if a plant gets too much, it will become tall and spindly). Blue light regulates plant growth, which makes it ideal for growing foliage plants and short, stocky seedlings (but too much will result in stunted plants).

Should lights be on during germination?

The answer to this one is simple. Your grow lights should be turned on (or your seedlings should be put under lights) as soon as the first seed starts to sprout. Many types of seedlings grow very fast, and they will begin reaching for the light as soon as they emerge. So give them plenty of it right from the start.

How do you know if your plant is getting too much light?

If your plant is not getting enough light, the most common sign is the yellowing and dropping of leaves, stunted leaf growth, elongated stems, and a dull-green color. If your plant is getting too much light, then its leaves will have singed tips, burned patches, or will be falling off (yikes!).

How high should my LED light be above my plants?

In short, LED lights are the go-to type of light used by gardeners. Since LED lights produce far less heat compared to other types of lights, plants can tolerate LED lights being much closer. A general rule is that LED lights should be about 12-30 inches from the top of your plant.

Should I dim my LED grow lights?

Dimming the lights is necessary when your plants are stressed or during application of foliar and pesticides. If you choose to include dimming control in your LED grow lights, you can make sure that you are providing the right amount of light in every stage.
