Advice needed on ventilation.

Hi there,

I'm looking to start a new grow soon but I am having trouble finding the correct requirements for my situation. My 2x4x5' tent will be in my basement, near a window which will be ducted to the exhaust. It is imperative that this be an odorless setup, therefore I need to have the exhaust fan continuously running pulling a vacuum (Can't have backflow through intake). I'm having a hard time locating a variable speed fan controller with a MINIMUM setting so the fan can never actually turn off, but will ramp up as temperatures increase. I've seen that there are some products like the 'Control Freak' but I've only come across ones with UK style outlets. Is there anything comparable to that in North America that doesnt cost $500+ or am I just blind/ignorant? I've only found manual controllers which won't really work for me, has to be automatic. Looking to spend around or under $300 if possible. Humidity control is a bonus but not mandatory.

Any suggestions or thoughts would be greatly appreciated, I look forward to hearing your comments!

Kind regards,

skybike

I just picked up a that exact titan controller. They are 100% worth the money!

Just get a fan that’ll pull more than 100/200cfm extra and that’ll give you negative pressure. Like how a 400cfm In-line fan will work perfect and such in wide on. 4x4x6
