Balance the elements

Processing: 20211016_115055.mp4…

Im setting up my indoor grow area and confused as to how to monitor and control the temp, humidity. I have a constant-drain dehumidifier set for 40%, small 5000btu window AC set at 1.5, humidifier set to medium. I set the AC Infinity T-4 fan but this morning there was 30% humidity and 90 degrees (F). The ranges I set were 40-55%humid, and 71-80 degrees. I’m not sure how to regulate the elements. Help. I’ll be planting 5 Purple Kush Auto(indica) and 5 White Widow hybrids.

I use the Sensor Push for monitoring temps and humidity. Only downside is it erases after 1 full year. You can probably find a cheaper version on Amazon. I bought this one as some others here bragged it up. Even after a full year the battery is still good. :+1::+1::+1:

I use these

Super cheap and super easy.

Your going to want some controllers to control all that gear but first I would just run the lights and work on dialing in the exhaust fan, run it on its lowest setting and see where your temp and humidty sit.

Then if you need more humidity kick your humidfior on.

When plants are small they don’t need a ton of air exchange, keeping the temp and humidity in line is key though. That’s where a controller or at the very least a timer can come in handy to kick your exhaust fan on once and a while to control heat but allow humidity to build.

Once the plants have grown a bit they will produce more humidity and will need more air exchange so then a constant air exchange is key. This is when your humidity can drop low and fabric pots will also help. Just run your humidfior as strong as you can and do your best.

If your humidity is high then you’ll need to run your fan at high to try and vent the humidity and run a humidfior to try and absorb it, however dehumidifiers produce alot of heat so the exhaust fan will also need to run.
An AC unit will also dry things out. So running an AC unit rather then your exhaust fan if your humidity is high may work for you considering how close it is.

It’s a good idea to think of where the heat and humidty is coming and going.

It takes practice.


Thanks. I have a question: you said:
“It’s a good idea to think of where the heat and humidty is coming and going.”

AC, Dehumidifier and Humidifier all outside the the grow area but in same room. Fan is in tent area.

just bought this bad boy lol

12″ (315mm) Silenced Hyper fan V2 – 3100 m3/h
The most powerful EC inline fan of its size, class and price, all wrapped up in acoustic foam and sealed housing to make it the best silent grow room fan

vs AC fans

Digital fans are quieter and use half the electricity that AC fans of an equal size consume. Comes with a fan speed controller as standard for easy control over the speed of your fan, running between 0% – 100% power.

Superior noise dampening

Housed in acoustic foam and a silencing cannister to dampen noise, without restricting your airflow. Did you hear that? No, neither did we!

Best-in-class power

The 6 inch inline fan is only 150mm and the most powerful fan for its size with a maximum airflow of 535 m3/h, making it ideal for smaller environments like grow tents.

Made for efficiency

Designed to generate immense static pressure, so even when your carbon filter, metalwork and ducting are attached – you’ll still get plenty of air out of your grow room.

@Nicky let me tell you its perfect and quiet i love it
