4-6 is pretty damn close. Heat and spread might cause issues. Maybe the 3w LEDs you mentioned from Steve's would work better
This is just for a germination/young growth area. I want something that will prevent stretch in lettuce seedlings as well as special herbs. Basically something that will give the same characteristics as a T8 6500k fluorescent but more efficiently
Do you live near a home depot?
Has anyone successfully grown plants under the T8 replacement led's?
Not that I'm aware of.......they just bumped up the specs on these led tubes. For veg I have no doubt that they would work fantastically. .......Spread out directional lighting
Unless you run them very soft or dim them drastically, I believe that high powered cobs will burn you babies that close. I could be wrong but I wouldn't do it. If its a light for seedlings I think the led t8 will work better and be much cheaper for yoy
