They are 125w cfl's that have 2700k and 6500k in one bulb. http://www.amazon.com/gp/aw/d/B009N6YQR0/ref=redir_mdp_mobile?redirect=true&tag=dodolawak-20
I plan on growing from seeds, from start to end. I figured this would be ok since these bulbs have both spectrums required for vegging and flowering. I plan on running a micro-grow with 2 plants and 2 of these 125w bulbs per plant.
