stelthy said:

Hi, basically as the title depicts I am ready to buy an AC unit... but am not to sure whats good and whats not and what size BTU? that I'll need..

I have a 2 plant DWC cab with a selection of 250w, 400w, & 600w HID lamps used (one at a time).. but my main prob is the INSANLY HOT WEATHER that were having... my grow room should 'SHOULD' be 26 oC but with this heat wave its between 33 oC and 37 oC and thats with my in-line Prima Clima fan on full...

My Res should be 18 - 20 oC... but thats 33 oC so bad times !! I looked into water chillers but they carrier a very large price tag..

So..

I am wanting to get an AC unit, my cabs in my Bedroom, we have no vents in the room, but have a few plastic windows (Double Glazed) if that matters ???

I want ultimately to cool both my cab and the room its in...But depending on cost it'd be nice to cool the whole upstairs (3 small rooms) ..

What is BTU ?? and how much do I need ??

Please reply asap cos I am going to buy the best one that some one on here surgests, cheers - STELTHY

you can take these other peoples info if you want.. but, fact is, if you want a QUALITY and reliable portable a/c unit.. that requires little to zero maintenance.. then you should look at the 'Commercial Cool' 11,500BTU unit. I got the black one. It comes with everything you need. It's an A/C unit, heater, dehumidifier and humidifier rolled all into one unit. Comes with a wireless remote.. and on the front of the unit, there's an blue lighted LCD screen readout.. that tells you the current indoor temp and time. It's a great unit.. and since I've been in the central U.S. during these INCREDIBLY HOT summer months (outdoor temps have been 100`F to 115`F for the past 4 to 5 weeks now.. EVERY SINGLE DAY.. with night temps only dipping into the mid 80's).. I've been using this thing every day, all day.. and it's still running like new man.

I paid $400.00 for mine.. but I'm telling ya.. its worth the money. It sits on caster-roller-wheels so you can move it anywhere you want it, at any given time. Just simply unplug the unit, and if your using the window kit for the exhaust tube, just simply twist the quick-disconnect to detach the tube from the window and the same for the rear of the unit.. and there ya go.. your able to roll the unit anywhere you want it. Only time you have to use the exhaust tube, is when your using the A/C function or the humidifier/dehumidifier functions. So, in the winter months.. you don't even have to worry about connecting/using the exhaust tube.

It's the best unit I've ever owned. Come to thing about it, its the portable unit I've ever owned.. and its the only one I'll ever buy. Very impressed with this unit.

and no, I'm not paid by 'Commercial Cool' or any of their partners.


peace.

EDIT: here are some pictures of mine, taken the day it arrived via UPS.

ok I know this thread was from earlier on but instead of making a new one (i'm also about to buy an a/c) I would just get some opinions on which type to get
I have a 1000w hps thats currently not running in my sliding mirror doored closet because the temps were so high. the humidity is around 40% mostly.
you all have already provided a good deal of information so I guess my only question is should I get a portable 7000-11000 btu a/c or a less expensive evaporative cooling unit?

NO get a 600....

sorry, a 600? I just edited what I was trying to ask [should I get a portable 7000-11000 btu a/c or a less expensive evaporative cooling unit?]

To be honest I have not read your entire thread so not quite sure what your problem is, I just thought a 1000W in a closet is pushing it so said a 600 would be a better fit. Ignore me and good luck

np not trying to jack the thread or anything I just have the same problem but with an hid instead of led light. I've done a little research and would like to know I most portable a/c unit can humidify and dehumdify or does it onlly work one was? I don't wanna dry my plants out so thinking about just workin on some ventalation then go the cheaper route with an evap. cooler thingy... any opions would help me out really need to get this gr up to par

Im running a delonghi 12k btu portable ac and it has ZERO trouble in keeping my 600w grow cab and surrounding area cool. I have the AC positioned right next to, facing my grow cab, and the exhaust pulling air off the lamp on the opposite side into the same room. Only problem I had was the AC's built in thermostat reading the temperature of the room, instead of inside the cab. however I played around enough with the settings to have it working good i read somewhere before that a 600w lamp puts out ~3500btu per hour. Theres a simple enough way to calculate it as well but Id need to find my physics book

If you manage to find the physics book I d be very interested to hear the calculation and pending answer - STELTHY

everything is all good and done but what about light leaks? i mean when you set up the portable ac in a window the exhaust tubes running from the plastic dongle thing sitting in the window? any trouble or info on that?

Sorry couldn't find my book, but I did manage to find some info online.

1 watt = 3.413 BTU/Hr
therefore:
250 watt lamp =853.25 BTU/Hr
400 watt lamp = 1,365.2 BTU/Hr
600 watt lamp = 2,047.8 BTU/Hr
1000 watt lamp = 3,413 BTU/Hr

Theory behind it:
Watts = Voltage x Current
1 Watt = 3.413 BTU/Hr

BTU/Hr = (Voltage x Current) x 3.413
OR
BTU/Hr = (Watts) x 3.413 BTU/Hr
