Trouble cooling 4 1000watt hps!

MyNamesNevin · May 20, 2016

Hey guys im currently running two 14000 btu ac's each can cool an area of 500 square feet my tent is 100square feet.
I have 4 separate inline fans (one for each light) they are blowing are across the lights.
I am exhausting all hot air out of the room but it still wont cool luckily im not in my flowering stage yet temps are getting into the low 90s.
Any help will be greatly appreciated thank you.

Are you growing in hell? With proper inline fans and insulated ducting .. And two 14k btu units I'd say you have plenty of cooling action. But so you know those acs are quite garbage . When you upgrade to building a room go with a mini split Ac.

You may be moving to much air through the tent. So the AC units are not only trying to cool the tent but also the entire room the tent is in. Try moving less air.

28k should be able to cool that room even if it was sealed

Thanks for the responses guys going to try a few things.

try getting 1 inline to filter out smell, use 2 inlines to cool the hoods or just one inline exhaust out of area, then oscillating fan to go over canopy. and try just one ac unit venting into , and exhaust out of a window. somehow your still getting heated air back into grow area

I run 9x600 hps with bat wing it can get very hot here over summer. I don't use any AC at all but I use 4x10 inch fans 2 in and 2 out each pulls 1019 cfm. The 2 fans coming in the air is been drawn from under the house. The other 2 fans with filters on them drawing the air out through the roof.
It runs prefect and most of the time I only run 2 of the fans

You could raise your filters higher up and have your intake as low to ground as possible, to the point of most resistance, thermodynamics.

Hey dude. This is above my experience level with all that ac and that any 1000watts but theres defo something wrong.
Post some pics if possible and describe how you vent out or where the hot air goes and where your cool air comes in. As said above a sealed room with that set up shouldn't be that problematic let alone a vented one.

sell the aircons and the 1000w'ers and buy 4 x 315w Dpap LEC

Got the temp down to 86 by rearranging my ac units im planning on running co2 would that be an ok temp to run with?
If not i will probably drop two of the thouies to 600s and see what that drops me too.
I appreciate all the help hopefully i can figure this out.

MarcMellow · May 26, 2016

From what I have read 86 is an acceptable temperature if you have CO2 enrichment during the vegetative stage, but I don't think you would want to carry that all the way through flowering. Below is a general recommendation for a DWC setup, and as the graph shows, they like to start with the higher temp and drop from there.
Hope that helps!

Slow down the exhaust or seal it. Make sure the a/c is also set up properly.

Hey that's a beautiful graph, where did you get it ? id like to store it

MarcMellow · May 27, 2016

That graph is located on the Under Current website. Here is a direct link: http://cch2o.com/general-recommendations/
It's definitely a nice chart to have!

MyNamesNevin · May 27, 2016

Thank you all for the responses!
I suppose i still have some things to change then.
Temp finally dropped to 82 last night by adding bigger oscillating fans.
Still debating on dropping two of the thousands to 600s anyone have any suggestions?

MyNamesNevin · May 28, 2016

bump.

That's because you are using 4kW worth of HID lighting. You are growing in Hell.

ttystikk · May 28, 2016

Something is seriously wrong with your setup somewhere.

Be certain that you aren't accidentally drawing air into your space that's been heated by the AC units.

In fact, with 28K BTu why are you drawing in any outside air at all?

Please don't tell us you have the WHOLE AC UNIT INSIDE?! You know they make more heat than cold, right?
