    First off let me congratulate you on the epic sketch.... but where does the out take pipe go? Vent the air out side, away from the groom so the air isn’t recycled and you should see an improvement.

    You need a dehumidifier mate. Also the floor fan will be circulating moisture around from the pots, raise it a little

    Probably not, they're not much use. You really need a proper dehumidifier if you're having that much RH, you will end up with rot

    Ah! So your RH is being affected by the ambient RH

    A dehumidifier is probably the only answer... but you should get away with using it only when the ambient RH is high. I would say look, possibly, at HPS lights but they may cause you low RH
