i just confused because all the fans i see for sale only move like 100+ cfm... so what fan should i get? oh also root doctor if its possible to get me info on your ventilation system of your grow room it will be very apprecaited like what fan you use and the cfm...
lazy smoker7 Reviewed by lazy smoker7 on . Help me find a fan. How much CFM do I need? OK my grow area is W 4ft x L 6ft x H7ft .... how much CFM do I need? and when I find the cfm do I buy 2 fans? because I would like to buy a fan off insidesun.com and I nottice they sell fans like ex: inline fan 200 cfm or whatever... so if i needed 200 cfm I would buy 2 200 cfm fans to ventilate my room? Thanks if you could help Rating: 5
