I'm using cfls for flowering. But want to add a cheep floro fixture. Are T5s the only thing I should use. Or can I use any floro fixture and what would be the min wattage. Can I use a T12 (I think) I want to put it above the plant and the cfls on the sides. Thanks. Would 45w be ok ? I'm in my 7th day of flowering. See a lot of spikes. But those aren't the sex are they? Only 1 plant
