I've been having trouble keeping the temperature down in my tents, and I'm wondering what everyones tips and tricks are for extra cooling without adding more to the power draw. Any suggestions are welcome. Thanks! :pray:

This is every growers nemesis. Open all your vents at the bottom of your tent. Also I've noticed you have your power bar along with other power supplies that you could move outside of the tent. Try it out and I guarantee you'll shed at least 1 deg. The only way to really reduce the temps considering you are already running an inline fan is to intrude AC to the tent. You can make a cooler packed with ice a homemade AC system but you need a fan to push that cold air in the tent there after so there is no easy solution my friend! We are all dealing with the same issues during the summer if you do not want to add with the additional power draw. Try moving your power bar and any other things that create heat outside the tent and you will see a difference, only issue it may become less convenient for you in the long run.

i would install bigger intake outtake that should fix your problem im running a 6 in intake + 10 in out whit dimer

and bring your light further

You could have your lights turn on the coolest part of the day. Say as soon as the sun goes down.

All these guys telling you ways to lower the temp in your room but your temp reading at 25c is not too hot at all.... But open those tent flaps up and let some fresh air in will definitely help out.

Hey there, so like others mentioned running lights at night is a good option. Otherwise if you can cool down the air outside the tent then the incoming air will at least be cooler, via open ports or intake and exhaust fans. I ended up trading my small clip fans for 2 4 inch ducts fans (1 in and 1 going out) and this greatly lowered my temps and humidity a little bit also, it also still managed a good breeze on the plants. I didn't notice any changes in power bill etc. I also bought a surface temp gauge for very cheap and it was surprising how less hot my leaf surface was than i assumed based on the room temp.
Keep up the good fight.:v:

add just a bit more to the power draw for an evaporative cooler, cheap, low energy, and easy to maintain, they'll get your grow room temp a few °C cooler and the plants love it. Hope this helps ! :rocket:

Turning the lights on during the night is a great way to keep high (and low) temperatures in check. Moving the grow tent / box into a colder room helps too, if you can keep the window open to allow cool air in the room it helps too.

Im having this problem and I may go down to 2 plants for the rest of the summer and turn my lights down from 240watts- 135-150 each. The non electric methkds i can think of are : Switch lights to come on at night. Straighten out your air ducts, any bends and twists will greatly reduce your air exchange. Turn down your lights, if possible. Add another intake opening at the bottom, and decrease the temperature of the air going in. Adding more fans to a tent thats too hot will just move hot air around, the air coming into the tent has to be cool. Good luck !:four_leaf_clover::snowflake::snowflake:

Hi @Smithicus! Since you've just jumped into the flowering stage, I would recommend to turn your lights on during the night, this will help in regulating the temp. If you can drive the air of your tent out of your house, it would be even better. You can build a DIY air conditionner with the help of a bucket, small fan, iced bottles, but it's an intensive work to keep the bottles cold enough. If your lamps are dimmable, you can dim the driver to the lowest voltage, for a few days only. So many of us are experiencing the heatwave :confounded: Good luck with that, keep us updated and happy growing! :facepunch:

Hi there mate , Have you got an exhaust fan? The inline type ones don't use very much power and in my
opinion a must have in any tent as good airflow (new air as apposed to the same old stale air) is imperative when trying to maintain a microclimate. I see you have a clip on fan I personally reckon they are not adequate and use a regular sized desk fan or similar with the oscillating function. They blow a lot more air around and dont use a lot more power than the clip ons.
Hope I have helped mate Good luck with however you go.:grinning:

The only thing I know to do without adding any more power is to schedule your lights out time for the hottest part of the day. Other than that your only real options are to pull air out or ac to cool the air in the tent. Good luck on your grow
