Temperature Challenges

[Med Grower]

I am a novice grower working in my first grow. I grow in two tents in my basement. I am working on getting the environment under control to move my plans from veg to flower and I am having a problem with temperature regulation.

Using an Apollo grow tent and a 10,000 btu ac unit in the tent with a 50 pint dehumidifier outside the tent. I am using a flex duct and wye with my dryer duct to vent the hot air outside.

I can't get the temp in the tent to get below 80 degrees even with the ac set to 60. I have tried opening the tent for more air flow and zipping the tent shut with no changes in results.

Any assistance would be great.

Do you have a dimmable ballast?

Also is the intake fan sucking from the same room the aircon is ducted to?

I have a dimmable ballast for a raptor hood. But I have not been using it since I am trying to get the environment right before flowering. I have an inline fan. But it is in the tent, not connected to the duct since the plastic duct from the ac connected to the flex duct.

When you drop you light time to 12/12 it will help with heat. The extra off time lets the temp drop before lights come back on. I also flower only during nighttime hours. Cooler nights help keep temps down.

Where are you pulling in air to the tent from?

 

[Med Grower]

Thanks for the response. However these temperatures are in a dark tent. There is no light on in the flower tent currently. With the light on its over 90 in the tent.

Do you have a filter and fan at the top of the tent... If you have then try and point the ac down to push the hot air upto the filter

I'm pulling in air through the vents in the bottom of the tent. I have also tried unzipping the tent to allow for more airflow

Is that air being pulled from the same room your ac is ducted to?

I have a can fan and filter at the top of the tent

My tents are both in the basement.

My tents are both in the basement.

Is that where you're pulling air in from? What is the temperature in the basement?
Is your ballast in the tent too?

Temp outside the tent and inside the tent the same. Ballast outside the tent.

Only way it's going to cool down is if you get the basement temp down, or pull cooler air from somewhere else into the tent

It's pointless pulling air from the same room that fit air conditioning unit is sending air 2 because it will all be the same temperature.

You need to duct the air conditioning exhaust completely out of the basement.

As well with your tent exhaust. If you can somehow vent to another room or even better, outdoors, you should be able to bring temps down.

you could try to have both ends of your exhaust system outside of the house

Check your basement for old furnace chimney. Lots of places with upgraded heating systems still have the old chimneys in place and can be used to exhaust heat and air. your problem has to be solvable. A basement should normally be cool so all you got to do is find a way to get the air out.
