You can use LED lights to start your vegetable seeds indoors and you don't need special plant grow lights to do so for plants that will eventually be planted outside. Upgrading to LEDs is just a simple matter of replacing your current tubes. LED plant lights use less energy and emit less heat than compact fluorescent lights, reducing costs and simplifying temperature control in enclosed environments. Go with full-spectrum LEDs (which don't look purple) for growing seedlings, propagating plants, and perking up houseplants in winter. You can use any LED Lights to grow plants, but that doesn't mean your plants will grow healthy or efficiently. So the short answer is yes. You need to ensure your plants are receiving light from a full spectrum LED light and that only comes from the best LED grow lights. A: Stick with ordinary fluorescent lights. They are readily available, reasonably priced, and work well for seedlings. Combining a “warm” white tube with a “cool” white in the same fixture will give the same results as a pair of special “grow lights. ” The best are probably 4-foot-long shop lights. 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.

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 super fast, and they will start reaching for the light as soon as they emerge. So give them plenty of light right from the start.

The G8LED 240 Watt LED Grow Light is for 2-4 mature plants, with a distance of 12-24 inches from the top of the canopy. The larger G8LED 450 Watt LED Grow Light is for 4-8 mature plants, with a distance of 14-30 inches from the plant canopy.

For the average home gardener starting seedlings indoors, a fluorescent or LED lamp will usually be the best choice to ensure that your plants get the quality, intensity, and duration of light they need to stay in peak condition.

Different color light helps plants achieve different goals as well. Blue light, for example, helps encourage vegetative leaf growth. Red light, when combined with blue, allows plants to flower. Cool fluorescent light is great for cultivating plant growth indoors.

Using a 60-watt bulb means you can put the seedlings within 3 to 4 inches of the bulb without harming the new leaves and stems. When you use a stronger bulb, such as 125 watts, it's best to keep the seedlings at least 6 inches away. This distance is too far for ideal seedling growth.

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.

This will allow the soil to slowly absorb water incrementally, until all of the soil is thoroughly wet. Take notes, make calculations, and get your plants on a watering schedule. Setting a cycle where the plant needs to be watered every two to three days is ideal.

DO remove the plastic humidity dome after your seeds germinate. Domes are really only used on the trays until the seeds germinate, which for some varieties may be as few as a few days. Once your plants have popped up, they need lots of air and light. Left on too long, domes can kill seedlings.

Moisten the newly planted seeds with a mister or a small watering can. To speed germination, cover the pots with plastic wrap or a plastic dome that fits over the seed-starting tray. This helps keep the seeds moist before they germinate. When you see the first signs of green, remove the cover.

Go higher than 5000K, and so much red light is left out from the spectrum your plants will grow slowly and without much vigor. But at the end of the day, plants will “veg” and “flower” under any kind of light.

Incandescent lights are good for lighting up a room or growing low-light houseplants, such as vines, ferns or dracaenas. They have limited utility for growing plants with higher light requirements. These lights put out only about 10 percent of their energy as light while 90 percent is heat.
