Well see I've got a problem with that.... A money problem... I have a 1000watter that I could use for 16 plants in larger pots for a while but I need a couple of fans before I can use my big light... So I'm saving up and going with the t5 untill I buy two duct fans... So untill I get them I have to fit all the plants under the one T5 set up I have going on now...
