You should pick up a few 42watt cfls for side lighting. The one big cfl at the top isn't really enough and doesnt penetrate the canopy that well. 2 42watt cfls on each side would greatly improve your lighting
ive added some extra cfl side lighting and started to lst them,hope full this will help with the canopy penatration,ive added 7 more cfls,all are 20w each,so the total wattage for the grow is now 388w,any more help would be welcome..peace
