I ordered all the goddies for the room. I'll be doing my first grow with a 1000w switchable MH/HPS in a 18" cool tube. Venting is 6" with a 440cfm inline exhausting through a 12"x26" activated carbon filter. The walls of the 5'x4' grow area are lined with 2mil mylar. Once I get any problems worked out in the first grow I will set up the other 5'x4' area so I will have a veg/clone and a flower area. This is a soil grow. Is there anything major that i'm over looking? So far my only real question is should I put a inlet filter on all the ducting? I feel like it needs something to keep the lamp nice and clean. Pics are coming soon!! Thanks.
