Regarding this, how far should grow light be from seedlings?

TIP: Place grow lights directly over plantings to mimic natural sunlight. As a rough guide, incandescent grow light bulbs should be at least 24 inches over your plants. Fluorescent and LED lights have a lower heat signature, so they can be placed 12 and 6 inches over plants respectively.

Subsequently, question is, how far should a 1000 watt LED light be from plants? So, for example, a 1000w HPS distance from plants for bloom would start at 36 inches and gradually move closer.

Similarly, are LED lights good for 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.

How far away do I keep my grow lights?

In general, with HID (High Intensity Discharge) lighting—including MH (Metal Halide) and HPS (High-Pressure Sodium)—individual 1000-watt lights should be kept 24 – 30 inches from the canopy; 600-watt lights should be 18 – 24 inches away; and 400-watt lights can be as close as 12 – 18 inches from plant tops.

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.

Can I leave my grow light on 24 hours?

Because dark reactions do not require the absence of light, plants will remain healthy when exposed to light 24 hours a day. There are some plants, however, that will survive but not thrive without darkness.
