Damp traps, increased extraction and increased temp will all reduce humidity. But at this time of year, you'll always be dealing with the ambient humidity, which is very high.

Dehumidifier from argos, £30...

That's the difference between professionals and non-professionals, the plants will grow to their full potential with the right humidity at the right stages in life

Although seriously how wet is your soil/medium to have that high humidity under a hps, they are notorious for drying out the air compared to other lights, do you have your feed bucket in there or something? if you do, remove it from the room + when you go to feed, put bucket in bath and run outside under hot water to warm the feed up before feeding so you don't shock the plants with cold feed

Relative humidity is at 93% today (south England). Unless you can dry the air in your drying room you're weed will take months to dry, if it will dry at all.

As @@SensiKey has mentioned, a dehumidifier is perfect for lowering RH but you really need to keep a sharp eye on things as they can dry the weed out too quickly. Some dehumidifiers allow you to set the RH to a % level you want. These are ideal.

I use a de humidifier from start to finish. In this country there is no way round it. I increased extraction, used a forced intake, but still had 70% rh , so my humidifier keeps it at 45% rh ;) I leave it on through drying process also. I actually own 2 as where I am it's pretty much water instead of air lol

under my 600w hps in a 1x1m sq tent with 2 x 4" inlet ducts with no fans to bottom of the window and 5" extraction to top, i get <= 20% RH, even on rainy days? different lights dry out the air more than others, hps is notorious for drying the air out, hence another reason why to use hps in 12/12 and a MH for veg?

Doesn't dry air make them more resinous and crystaline in the last few weeks?
