How to control the temperature and humidity of grow tents?

[Emma2016]

I am a novice, as the title, how to control the temperature and humidity of grow tents? By the way, I want to buy a led grow light, someone recommended me the Lightimetunnel on Amazon, anyone has experience with this brand?

Extraction fan and intake would be a start then humidifier or dehumidifier could dial it in exactly where you want your temp and hum. To be

An easy way to try to achieve the perfect temp in a tent is to have the surrounding temp/humidty where you want it. With your extraction fan on (inside the tent) it will suck in the air quality you want in the tent.
Hope that makes sense....If not research lung rooms.

YES!

Don't over look having a fan (of some kind) with in your grow space to provide air movement/circulation with in your grow space too.

If you are using a fan to remove air from the tent/grow box (lets just assume you're using 6" ducting), the less resistance on air flow that you have moving through your box/tent will affect the temp with in the space while your light(s) are on. If you are pulling air out of a 6" duct and only have a 6" intake, you have resistance on how much air can flow in through you 6" intake. If you add a 2nd 6" intake you double the amount of air that can flow into the garden space and you'll see a drop in a couple of degree's, add another 6" intake and your temperature will drop a little more.

Here is a good brand of led, they advertise on here in the led lighting section under grow room design. They give discounts for icmag members and have a 5 year warranty!
And a well known member krunchbubble has a grow using these lights. http://www.starlite-led.com

They give off less heat so you don't need to spend as much for cooling equipment.
I have no involvement with the company, I just respect and trust krunchbubble as a grower and have followed his adventures on here for years...

Word of advice with tent and extraction, be careful to match both intake and exhaust fans or your tent will surely either blow up like ballon or suck in like ya trying ta purge ya tent. All bullshit to side a weak tent can be crushed by exhaust fan.
PEACE!

definitely use a Lung room
and absolutely school yourself on Vapor Pressure Deficit.... can't stress this enough as it IS the key element for success in a grow tent in my opinion and will dictate your heating/cooling/airflow
I don't use AC , just lung room with window open for cool evening air.
tent is passive intake so no fans on intake.
light has a 14" fan blowing straight up underneath it
I use a small desk top fan near the inside of one passive intake to blow air horizontally and an exhaust fan in the ceiling sucking air out and venting it out of the room. I did my best to achieve a temp and humidity matching the VPD chart for my space and light.

I forgot to add a good environmental controller is a sentinel GPS BEC-1A it's one of the few that will run in cooling mode, dehumidifying mode, or both so you hook it up to one exhaust fan. Works best when used with a lung room.
