ok let me put this in a different format.does any one have 3 lamps linked together "ventillation wise" with a 35-40 foot run of 4 inch ducting.if so what cfm fans are you using.at the moment i have a 10 foot run with 2 600 watts and a 325 cfm. fan pulling the air. before i go ripping everything apart is there a minimum cfm rating for 3 lamps at 40 feet????
disrupt86 Reviewed by disrupt86 on . ventilation gurus help!!! quick question,right know i have an ideal setup of 2 x 600 watt in a 5 x 10room,however i need another lamp a.s.a.p. up until this point the room gets ventilation from a seperate room and exhausts into our main room"wich gets pretty hot. im afraid by adding another lamp its going to affect my veg room.i need some input on my idea, i have 30 ft of 4 inch schedule 6 abs pipe.my plan is to run all three lamps with my current 6 inch fan then reduce to a 4 inch reducer" to accomodate the piping" and Rating: 5
