I just set up 2 2000w leds (300w true) in a 6x4 box. I'm going to germinate seeds in rockwool but it's going to use these lights. How high should I hang them, considering their power?
I will only use one at first. Thanks for the advice. When they go to seedlings I can revert back to 36" and reduce height as she grows right?You don't need both of them on, and they don't need to be close, 3 or even 4 ft is fine at first.
Word. Sounds good. Only have a small cheap light right now that had to stay fairly close. Wasn't sure how to go about it with the big boys. No soil, dwc btw. Thanks for the advice. Here's the new box.The amount of lights don't matter.
30"-45" above the soil level. 13.5k to 15k lux at soil level.
Let them grow into the light. By the 4th node, they should be getting 17k-18k lux.
6th node, 20k to 25k lux. Light height of 2 feet. Maintain two feet height the rest of the grow.
