Yep, that's what I run too, works pretty well! I've got a dehumidifier that sucks air out of the tent and into the small room that houses the tent. The dry air then gets sucked back into the tent through the open vents. It took me a lot of trial and error to get this working well and I usually find the tent runs about 5% higher humidity than the dehumidifier is set to. I like to keep a beady eye on the VPD so for the first week or two I like to run at close to 70% then down to about 60% for most of the grow. 50% for the last few weeks. So far so good. This is a very useful VPD chart where you can enter your variables:

I kinda avoid the need for AC by switching stuff off when it's too hot. If you keep an eye on your DLI then you can still pretty much give them all the photons they need. All this is a lot of fucking about but that's one thing us UK prohibition growers are good at, fucking about! Anything for quality buds!
