    Dehumidifiers will not cool the air ... if anything warm it. Great to drop humidity though. Vital in the UK.

    AC can dry as well as cool air - but IME not great for drying. Also expensive to buy and run.

    You want a unit that drains to waste.

    Probably 12L per day. I use a 6L in half the size and I don’t budge above 35.

    Igenix do a self-evaporating unit so it will recycle the collected moisture and never turn off because a catch tank is full. AC all the way but just remember that the hot air needs to go somewhere and potentially needs filtered too.

    As you'll only need an air con in the summer, a dehumidifier would seem the obvious answer....

    My AC will cool and dry air. It is OK at cooling air, less so at drying. It will get the room, like today down to 19C. Venting out of a window.

    Today is quite humid, 74%. The room humidity is 50% using my mini hydrometer.

    However, in my grow tent, humidity is 31% due to the dehumidifier. As such, the AC is not the greatest dehumidifier considering the cost of running it!

    Temps and humidity are very different. Humidity in flower is important due to bud rot. Temps, as we are all suffering now, are less important. My tent is 42.2C at the moment! The girls are fine.

    Unless you got the cash, you want to control humidity as a priority and keep temps in range. AC is used in the States for instance, where it is cheaper to cool the whole room down (indoor grow). But then again a lot of the houses over there have built in A/C anyways.

    If your humidity is that high then you may also want to revisit your existing ventilation as it sounds like it's not up to the job....

    Try a 2nd hand one, you can pick up a 12ltr in the UK for £35 on gumtree, might allow you to get both... although I'm no expert and they may do the same thing haha!

    I bought them ... not worth the cash.... all three replaced within 3 months.... not up to the job. Noisy as well...

    I stupidly followed amazon recommendations :-(

    Get the rhinos and a decent fan controller - not worth going cheap!

    You want the outtake fan to be bigger than the intake fan. The out fan has to pull through the carbon filter.

    I use 6" out and 4" in.
