It all depends on how many CFLs you use. I use a dozen on each plant, six mounted low, and six mounted in the spaces in the canopy. I have buds from bottom to top, and her buds are now about the size of a nickle, which is pretty good for growing under 23W CFLs.
But I've followed a couple other grows that used CFLs exclusively like you do, and growth is clearly slower, right? How does his 25 day old plant look to you? It looks fine but slow. Do you think it could be from the mixed daylight times or just from fewer lighthours in general?
