This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.
Your light would in fact only be around 400 true watts and a 400 watt light will easley handle 4 plants and your distance should stay the same but I would only run it at half power at the start until your plants can handle it.
