CFL's is something I don't lack ...I just added a second 45 watter in the cab - so one is the equivalent of 200 Watts in Natural White and the one I just added is the equivalent of 150 watts in Warm white.

I'd prefer more blue spectrum but ...this will have to do. I've rearranged the lights so that one bulb is centimetres from the top of the seedlings and the other is a few inches above.
