Need help with understanding RH% Plus Temp.

Hey everyone first time grower here and having a little bit issues ( I think) specifically humidity.

1. So the problem is that doesn't matter if I crank the heater or place wet clothing inside the tent + humidifier running I cant seem to get my RH% up to 45% min I`m struggling to even keep it at 30% +mark. 82F only time I can build up humidity is when my exhaust fan plus intake fan are both off.

2. Growing auto flowers and my light schedule is 18-6 to keep it simple, I'm watering every 3 day(not scheduled, do it as needed first 2 weeks seemed like had to be done every 3 days.

3. I'm on my end of week 2 for seedling stage.

Specs: 2 600w LED Full Spectrum Aglex lights with Veg/Bloom switch. Running both switches.
Exhaust Fan: 4" + Carbon filter
Tent: 60''x60'x80''
Intake Fan: 4'' ( getting air from different room with average of 30% Humidity )
Humidifier: Set at 55% ( Can`t keep up, ran out of water before reaching 38% humidity )
Dehumidifier: not in use
Heater: Tower heater no problem heating up the room to 25degrees Celsius.
Last one: Lights are 26'' away from plants.
.... I have not started feeding nutrients. since its only week 2 seedling.

4. I`m not seeing any deficiencies on the plants quite yet but I`m hoping to have my indoor temps and humidity set proper before any of that occurs.

5. I had a spider web in the tent. Need help figuring out how to get rid of spider( hiding somewhere)

I will post some pictures of my setup after someone asks something etc.

This will help you understand temp and humidity for different stages of plant growth. Download the chart and calculator.

As far as not being able to get your humidity up, how big of a space are you growing in? I use an ultrasonic humidifier and those things can really put some moisture in the air. No filter so there's no worries over it getting nasty and causing mold problems. I got a little too lax about cleaning one a few years ago and ended up with bud mold because of it. I'm going to suggest you get these as well. It will really help you dial in your environment and it's as easy as set and forget.... It's not letting me link it for you, just copy paste this in Amazon...... Inkbird ITC-308 Temperature Controller with IHC-200 Humidity Controller with Outlet, 10A 120V

1. Ill check it out.
2. Im growing in 5ftx5ftx7ft (no problem with keeping up the tems heater might turn back on every 4-5 hours
3. And i did order both of em should be here this afternoon. I have no issues with Temp. so the temperature controllet probably could hook up to my exhaust fan, so when it gets 82F itll air it out. If im understanding that correct. And Humidity controller hopefully itll make use of itself cuz rn i dont really have too much humidity either

Yup hook your exhaust up to the cooling plug, it'll kick on when your tent hits the set high temp. In the summer hook it up to a/c.
