Can plants grow under normal LED lights?

Can I germinate seeds under light?

Light, light, light!

If seedlings don’t get enough light, they will be leggy and weak. If you’re growing under lights, adjust them so they’re just a few inches above the tops of the seedlings. Set the lights on a timer timer for 15 hours a day. Keep in mind that seedlings need darkness, too, so they can rest.

What color LED lights for seedlings?

Although plants use the full spectrum for photosynthesis, red and blue light seem to be most critical. Red light stimulates vegetative growth and flowering (but if a plant gets too much, it will become tall and spindly).

How many hours of light do you need to start seeds?

In general, seedlings should receive roughly 14 to 16 hours of light a day when situated in a south-facing window. This can be very difficult to achieve, and most growers opt to use artificial lights for their seedlings. These fluorescent lights should be left on for 12 to 16 hours a day.

Can seedlings get too much light?

Plants cannot get too much light, but they can get too much of the heat energy that comes with the light. Photosynthesis and other plant growth processes will shut down when the environmental and tissue temperature gets high enough that all the water taken up by the plant is used to cool the plant tissue.

How high should my LED light be above my plants?

A general rule is that LED lights should be about 12-30 inches from the top of your plant. As your plants grow, you have to change the height of your lights to accommodate the growing plants’ height.

Will 5000K LED lights grow plants?

5000k Vs 6500k For Plants

Both 5000K and 6500K white light is great for growing plants, but not as great for flowering them. It will still work fine, but a warmer color temperature would work much better.

Do seeds germinate better in the dark?

Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007). Don’t confuse seed light requirements with what seedlings need. All seedlings require sunlight.

What kind of light do you need to start seeds?

And there are two types commonly employed for starting seeds, tube types and compact fluorescent lamps (CFL’s). For folks that are pretty new to growing indoors or have a small space, the CFLs can be a great option.

What color light promotes germination?

Suffice it to say that it is mainly the light’s effect upon a plant pigment called phytochrome within the seed. This relates to the type of light which the seed receives. As a generalisation, light in the red wave length usually promotes germination whereas blue light inhibits it.
