How far should the LED Grow Light Fixtures be from the plants?


I'm using two PhotonBlast™ LED Grow Light Fixtures to start seedlings. Some I just started, some are perennials I started last fall so they are a few inches high. How far should the light fixtures be from the plants? 

As our LED lights emit a far lower heat output than traditional horticultural grow lights while oeprating, heat damage is generally less of a concern. As such, we recommend placing the lights as close to the plants as possible without them physically touching.

That said, we can easily imagine that different plant species could require a more precise distance from the light in order to receive the maximum lux benefit. We might recommend reaching out to a perennial or horticultural expert for a set measurement and advice.
