same size tent as my old one, an heat was always a problem unless I left the tent door half unzipped. I can recommend having a fan inside the tent, instead of blowing air from outside in, use your extractor to draw the hot air out otherwise it will just hinder and cause high humidity, especially after watering. Once you have the fan in there and your extractor sucking the hot air out of the tent, whichever room your tent is in, leave that window open.. You'll be surprised how much it helps maintain a steady temperature as the outside of the tent being cool will keep the inside of the tent a good temp. Otherwise the whole room just cooks, had that problem and I really didn't enjoy it! Let me know how it goes and hope it helps you out.

Do You have any where you can put your intake ducting where it receives fresh air instead of air from the same room or you could switch hps for an led they run a lot cooler

Also, you already mention that the water in the bucket is hot an smelly. Unless you can lower the water temperature significantly (below 20°C - 68°F), you are going to have root rot. You could consider using soil less media like coco. But if you want to continue with DWC, I've seen people using coolers adapted for DWC, their ability to keep things inside at lower temperature helps along with ice pack gels, if you can go around changing them over and over.
A few general tips, the ballast puts out a lot of heat (usually), don't put them inside the tent and if you can have a fan directed to it, it will help.
If you can, don't vent the hot air to the room, but to the outside.

in such cases, you can help the system cooltub - fan 190m3/h. Show up tents - how those departments are eliminated - the lamp, the fan.
Flavoursuk correctly speaks. and put the fan inside the bag.
