Good morning from the land down under. Been reading the t5/cfl thread and have gained lots of info . Thks all . The thread looks a bit dead so I will ask you learned people here. I have got my hands on some cheap 135w 5500k cfls, do you think they can be used in a 2x2x4 grow space or is the 5500k an issue. Thks for all the great info and looking to contributing where I can.
