Holy smokes, sure enough. Well, maybe OP really does have true 300W CFL... or maybe he doesn't have the light close enough. Bottom line, it is easy enough to get tight nugs with CFL!Ive seen one , actually iv grown with one , didnt get the best results but they where good enough for the light .. heres a link http://cgi.ebay.co.uk/300w-dual-Spectrum-CFL-grow-light-lamp-Hydroponics-/280705572406?pt=UK_HomeGarden_Garden_PlantsSeedsBulbs_JN&hash=item415b5b1e36 you can get them in duel or single spectrum
