well it's my first serious grow check my link. I am using cfl's right now I want to go with 250 watt md with blue led spectrum lights as a supplement when I start flowering as md through the whole grow hepls produce a higher thc content. I'm not a distributer so I don't need the high yeild. I just can't afford the high ass prices around here. Worth every penny I pay for it but what it cost me for an oz I can grow twice that plus some.
