to deal with humidity, i set my AC to the "dry" setting (acts as a dehumidifier,) and i use a 45 Pint dehumidifier from best buy ($250 w/ a 4 year extended warranty) and this usually stays on the low setting (i set it on low and 60% humidity. it comes out a 39% right under the lights.)

also, HIDs usually make things dryer. i use flouros for veg cause its easier to keep the humidity up
joedirte Reviewed by joedirte on . Dman3000's first 600W grow Hello everyone this is my first official grow and I put alot of money and time into it. I have them all growing in one of those lightproof Homebox tents; with a 600w MH and will be using a 600 HPS for flowering. There is a 6" carbon filter in it as well.Also I have the light in a air cooled hood connected to a 435chm exhaust fan (which also has a diy duct muffler connected to it). Inside is completely white for reflection purposes I am using fox farm nutes(growbig,bigbloom,tigerbloom), but Rating: 5
