High heat Low humidity

I'm a newbie as well and my first grow (I'm doing my second one now) had the same problem... I ended up having to leave some vents open or partially open... for your heat, I'd suggest leaving a couple of bottom vents open and definitely one on top (heat rises... bring in cooler air from the bottom and let the heat escape from the top). I experimented with a number of configurations before I got a handle on the heat issue. I don't have an issue of needing to hide the smell, thankfully ... if I did, I'd have to actually spend money on some filters and venting ... hopefully you don't have to worry about this issue! As for your humidity, you really DO need to get it up! Best (easiest and cheapest) way is to drench a couple of towels, wring them out and hang them in the tent... again, experiment with how many towels you need to achieve at least a 40% humidity level... I'd check the towels at least twice a day to make sure they haven't dried out... Good luck with your grow.... remember, there is no one right answer to everything... experiment around to find out what works for you! My first grow was 3 plants, each planted about a week apart ... so the first seed to pop up received ALL of my ignorance... the second got much better treatment and my third was a fairly happy camper all the way through... I'm now on to my second grow and feeling a hell of a lot more confident - but there's still so much to learn! 😊
