    try and get a dehumidifier with a constant drain and a setting for the humidity or you'll empty it 3/4 times every single day if it's not running to waste

    Best thing I did was fit one with an auto drain function.

    The UK is a seriously humid place. Recently measured 90+% RH outside.

    Near enough! Last weekend was high the whole time.

    I noticed the dehumidifier struggling, and an alarm was triggered. Only 3% but good to know at the extreme humidity levels.

    if youre pulling hi rh out through filter then i suspect youll be due a new filter soon,high rh kills filters,spesh a little 4"?

    youd also be better off with a 6" fan n filter in that space,certainly will need it if summer is another roaster like last year.

    you are using 4 inch fan and still have problem with high humidity. Move your grow tent to a well ventilated place. If this does not solve your problem then you have to buy a dehumidifier.
    for 1.2x1.2 grow tent a 4inches duct fan is enough.
