I am going to buy a DR120 in the UK.
What extractor fans should i be looking to get? I have a 250W HPS and high temperatures are not such a problem.

i have been growing in a closet and feel it's time for an upgrade.
i haven't controlled humidity before, so i am looking to get one of those temperature and humidity monitors?
any way i can hook up things to run automatically by themselves? e.g. maintain temps at 75degrees F? maintain humidity at 50%? so the extractor fan kicks in only when necessary?

i have seen rhino pro filters? is this what i should be getting?
are there different powers of these filters? do they last long or need to be replaced? do they consume huge amounts of electricity?
Fan & Filter Deals - Green's Horticulture
this is the website- they sell 3 diff types of fans and ducting, but i don't understand the difference.

any tips appreciated!!
