What does all this information mean?
I've been researching grow lights online, and I'm very confused. I am finding wattage, K, and lumen information, along with the red, green, blue spectrums. What is the important information? For example, if a light is 6500 K and 2000 lumen, is that good for starting vegetable seedlings? How does wattage play in? Sorry for the newbie questions, but very, very confused! These lights are so expensive, and I'll be doing several dozen seedlings, so don't want to mess it up on purchasing. Also, any recommended place to purchase? Thanks!
