Seedlings need 14-16 hours of light every single day, without fail. Don’t leave them on for 24 hours a day though. Like us, they need to rest at night.

How much light do hydroponic seedlings need?
You should plan your system on having at least 14 to 16 hours of bright artificial light, followed by 10 to 12 hours of darkness every day. The darkness is just as important as the light—just like animals, plants need time to rest and metabolize.
How much Grow light Do seedlings need?
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.
Do germinating seedlings need light?
All seedlings require sunlight. Seedlings will become leggy and fragile and will not produce to their potential if they do not have sufficient light. Table 1. Soil temperature conditions for vegetable crop germination.
Do you use grow lights during germination?
Add a light as soon as any green part of the plant emerges. The new leaves need as much “sun” as they can get to give the plant energy. I turn my lights on as soon as I sow the seeds. The light doesn’t matter before they’ve sprouted but it doesn’t hurt at that point.
How close should LED grow lights be to seedlings?
There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.
Are LED lights good for hydroponics?
LED’s can be a great addition to hydroponics grow rooms. LED’s can help reduce energy bills for the period HID lamps are not required, and then plants can get the boost in growth that these HID blubs still manage to deliver.
Are LED lights good for growing seedlings?
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.
Why are my seeds not germinating?
Mostly, extreme temperature and lack of consistent moisture are likely causes of seeds not sprouting or seedlings withering. Here is a list of factors that affect seed germination and the condition can be fairly avoided by taking care of these small things.
What are the 3 conditions necessary for germination?
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
Do seeds need warmth to germinate?
Seeds need both moisture and warmth to germinate. Warm up the soil before sowing your seeds. And warmth from below the seed tray is best, without allowing the potting mix to dry out. Keep in mind that high temperatures will kill seeds or dry out seedlings, so stay in the desired temperature range.
What color light promotes germination?
As a generalisation, light in the red wave length usually promotes germination whereas blue light inhibits it.
