nice tutorial but u forgot to mention that the 23w=100w actually means that the 23 puts out the same light intensity as a 100w but not the same lumen output.
u should ask to see peoples cfl setups,to compare and see there innovations. sry for jackin but just tryin to help out,ive been usin cfls for a few years now with no probs.
heres my set up...1 125w 6500k,4 42 3500k,total of 22,800 lumens at 293w,i had to take down the batwing reflector to help ventilate the heat out,since it has a fan site on top.
id like to join the cfl crew,cus if u know how to use cfls u can pull great yeilds,it takes skill and innovation to use cfls,hids are hot as hell and you need to keep them 2-4ft away from the plants,this can cause strechage to the maxxx
