I got a 2ftx3ftx5ft tent with a 4inch inline fan for intake of fresh air and a 6 inch inline fan for exhaust. I have two 240 watt led panels that I though I'd use one to start and add the second when I start flowering. Is this a good idea or use both from the beginning? I have cables that lower and retract to change height of lights but in my 5 foot tent I can get 3 feet from the floor. Is this close enough? Do I need anything else to get started? Any input would help. Thanks.
