Hey guys ,this is my first Grow , i have two new Mars ll 400 watt LED lights in a 4x4 tent. I need some good insight , on how far away to keep the lights . 3 Northern Lights regular feminized plants. Their about 2 to 3 inches tall at the moment , under a 2 foot long t5. Wanna move them to the tent, but need the input first. Don't wanna burn them or stress them by being too close , or cause them to stretch too much and fall over. Thanks for any help in advance

Hi there. The LEDs will probably have a lens which focuses the light beam. So as close as possible is not always appropriate for these lamps. It should say in the spec that comes with your light. If not, I would go for somewhere around 12" - 18". allowing the plants to grow into the optimum light area. Hope this helps.
