Im using 27W daylight simulation bulbs. and they seem to work the best just like that..i have three sets over my skywalker seed at times i will move one set of light vertically to get light to much of plant as possible.. heres another picture
V nice m8. If you can, add another fan to the mix and/or raise your lights ever so slightly, they look a little heat stressed from the curling of the leaves in your second pic.
