Exhaust Fan

[Stankrop]

Hi there, my exhaust fan brings the temp and humidity too low running all the time. If I can’t afford a humidifier and heater, how often should the fan run on a timer?

id run it in increments, have it kick on every 30mi or so. you'll have to play with it ad see what it does. if you have a environment gage (pulse meter, mendel air sensor) it's much easier to dial in

id get a humidifier and have run ever 30min-1Hr, as your exhaust is just gonna lower it into an acceptable range anyways. id also recommend getting an environmental tracker (pulse, Mendel air sensor) as they tell you your temps, Rh , VPD e.c.t and you can dial your changes in easier and when needed

Humidifiers are cheap. I splurged and bought an Inkbird humidistat. It’s changed my life and my routine.

I mean you are talking about two under 30 dollar investments. If you do get an humidifer just don't get an evaporative one. Get a cool mist that has an analog control knob, like a cheap Vicks one.
Otherwise you can hook your exhaust up to a thermostat or timer. Just monitor it and adjust timing as needed to make sure you don't get too hot. Keep in mind if using LED's your ambient temp can and should be in the low to mid 80s.

With a limited budget, you'll have to experiment with timer settings on the fan. I'd try running it often for a short period to avoid big swings in temp and humidity. You can also raise the plants up of the cold floor with buckets etc. My light is at the top and the plants are on a shelf that's lowered as the plants grow. My fan is plugged into an InkBird humidity controller.

What's wrong with evaporative humidifiers?

Dont worry much about humidity, focus on temps. i grow at 20-40% rh with no issues. looks like u could add another light which would bring temps up. exhaust fan should run at all times. if exhaust fan is off smell will leak out of tent.

Most evaporative humidifiers will not get you to humidity levels you want unless they are extremely large. Cheap evaporative humidifiers may help you keep a tent a little up but will be slow to raise and won't get you to the level you generally want.

Buy a cheap temperature controller off amazon, the inkbird ones work well. Set your temps for when your exhaust will turn on and off, no messing around with timers.

So you're exhausting into that room and it still gets cold? Anyway of warming the outside space up until it reaches a happy temp?

This^^^ They're only 30-35 bucks and will change your life. You can get a dual one that also does temps.
