    whats ur temperature mate? Increasing the heat in ur grow room or tent will lower humidity, cannabis thrives in ideal temperatures at 20-30c 60-90f. What ever the case there is too much moisture in the atmosphere, the room needs to be dryed out either by heat or as you said dehumidifier. Good luck with ur harvest. Peace

    My temps arent the same between on and off mate, temps dont stay the same outside during night and day so surely that is ok indoors no? and I might be wrong but those humidity% aint too bad, again mine are around the same as yours and I dont have any probs and your temp is better than mine I think, mine is about 30+ with lights on

    Water less is always a good start.

    I know you say ways to achieve lower levels without a dehumidifier, but I know homebase do a small portable one for 30-40 quid that helps. Been using one for a few years now and it definitely helps.. Out of interest what size grow space are you using?


    Anyone who says nothing is impossible clearly has never tried to slam a revolving door..

    got the same problem on my hands guys.. trying to lower Rh 4-5 weeks into flower.. lights on reading 50-60% and lights of 60%.. I heat the room up with a heater and it really lowers the Rh by 10-15% only if you have space to increase temps as the heater running without a dimmer/thermo takes temps to 30+.. looking into a buying dehumidifier to keep temps/rh low.. altho ive heard the small ones arnt really effective and we should always go for something bigger..? anyne care to comment on that...

    i have a few ideas i plan to try out.. with the dehumidifier 500ml tubs you can buy them very cheap..maybe place one in the intake or just near it..and a few around..plus someone mentioned rice in a bowl.. has anyone tried this yet..? i might try using some rice in stockings and hang them around..might help...
