thats a big space for a low budget. A 400 watt hps is good for 2x2 ft. also temps will vary a lot in an attic. does this attic have vents???? I would build a big cabinet and go with shitloads of 4 ft flouros. and maybe have 3 boxes ...... one mother box, one clone box and one flower box. use small quiet fans
harmonicminor Reviewed by harmonicminor on . Help me choose a light!!! I have a 8x6 space that I want to grow in in my attic. It is also 7 feet tall. This will be my 2nd grow. I'm only planning on using 7x5 space because I want to be able to move around in the space i am growing. I have one BIG criteria that I have though when setting up my room, NO NOISE AT ALL. By that, I mean no huge blower fans, inline fans, loud ballasts, etc. I may be able to run a small fan on a low setting but that's about as much noise as I can have. I've already got the space light Rating: 5
