Indoor Tree Seedling Growing: 6500K all the way?
I just purchased a T12 fixture with two 40w Daylight 2900 lumen 6500K lamps. My Acer Rubrum (red maple) seedlings are a range from newborn - two months old. Do I NEED to have a warm color lamp in the ballast or is that just for fruits and veggies?
Also, what do you think about getting a black light bulb as well? Maybe throw some black velvet in the pot for mulch? ;)
