Help! Over-heating problems

[fiireygrower]

Hey everyone.

I'm having problems with the temperature in my grow tent. I've read other forums but this is my set up so any help appriciated

I have a 1.2x1.2x2.0meter tent. 600watt magnetic hps ballast and a 600watt has grow lamp. I have a carbon filter running at the top of my tent with a 150mm 91 litre per hour in line axial fan with ducting out of tent.

I have 2 oscillating fans running in the tent but the temperature is always running at 28 to 32 degrees.

If I have my tent open it falls to 27 degrees. I have this running in my spare room so can't really have it open. What can I do to get temperature down.

Cheers in advance
✌✌✌

Do you have all the vents open for passive intake? Are you bringing air in down low where its cooler and exhausting the hot air up top?

Also if I understand, youve got 1 600w light with an old school ballast, is the ballast in the tent?

 

[fiireygrower]

I'm so new to this what vents will they be for passive intake?

The ballast is in the tent as well do you think this will add to the heat?

I have a seahawk tent. And they have flaps at the bottom that can be opened with mesh like material for airflow. The air up top is being exhausted out through a carbon filter then through an inline fan through ducting out of the tent

You carbon filter fan pulls air out of your tent. It is replaced with cool air coming in from open vents. The lower down these are the cooler the air coming in will be.

My ballast is digital but Ive read magnetic ballasts are hotter and if this is in the tent it is adding to the heat and may also be a fire hazard.

What is your light cycle? Are your lights on during the coldest time (night)?

Open them up

At the momental I try to have my lights on at night but they on a 18/6 cycle. It is nearly winter where I am now so not to much of an issue.

I ran my veg tent for almost a week with nothing in it just to dial it in, and still made mistakes. It takes time to get it all just right. You may have to cool the air in the room the tent is with, or exhaust the heat directly from your light. I have the opposite problem. My basent is and always will be too cold.

 

[fiireygrower]

So running the ocslating fans on the inside is still viable?? I have one running under my light to distribute heat more evenly and one at the bottom lightly blowing my plants while oscillating. This is my first time growing so all advise will go along way.

Will definitely take the ballast out of the tent open those vents up and see how much of a difference that makes

 

[fiireygrower]

How would you heat yours up then if it's always cold down there? ?

 

[JPinkman]

Keep the o-fans for sure. Moving air is a little cooler then stagnant air. Pull the ballast, open your vents and take a reading after a few mins. Make sure the vents dont leak light

 

[fiireygrower]

The vents do leak light. How would I change that.

I appriciate your advice

 

[fiireygrower]

I run my inline fan from in my tent too

 

[JPinkman]

There are probably several ways, but the easiest thing I came up with was to intake from a round vent port using some 6" flex hose. Run the hose in a loop (pigtail) to light proof it.

See if you can pull it out. Anything that generates heat. Youd be suprised what subtle changes will drop your temp a degree or 2. I keep everything inside my tent (except ballasts) because I need the heat. I also like it to be as quiet as possible so my GF in her office above it dosent get disturbed at work

Got pics?
