Mini Split A/C units

Ok so i would really like to create a "perfect room" with a mini split AC to cool it

Now if it is completely sealed with no in or out vents and just an oscillating fan inside - will the a/c be enough to completley cool it?

Would i be better off using air cooled hoods as well or would i be fine with just say 4 x 600w barn style reflectors?

Id imagine that gets hot hot hot so i just want to know if the a/c will cool it all and how many BTU's id need per 600w light?

Thanks

There are a bunch of variables you are leaving out to enable anyone to give you an informed answer. Total cubic feet of room? Which route are you looking at going; air-cooled or open lighting? You listed both. Are you doing a controlled environmental grow, or are you going to be venting the grow room? If controlled environment, I assume you will be adding CO2. What type of CO2 unit will you be using; a water-cooled unit, standard CO2 burner, bottled CO2, or some other method of adding CO2? Are your ballasts going to be located outside your grow room, or inside? Will you have other equipment that generates heat inside the grow room? Is the grow room located in an attic or basement?

Too many variables to answer intelligently.

i was primarily concerned with the question of whether a sealed room with standard hps lights would be able to be cooled with a mini split unit assuming there are no in or out vents at all. If i was to go down the air cooled route then there would naturally need to be some venting of the lights.
Primary concern is heat signature for which the ac unit could be considered a good option as it does not look suspicious on the outside of a building and i am also curious to how much heat the ac unit on the outside of the building will put out? ie is it related to the number of lights used and does it pose much of a heat signature by itself so that it may look more suspicious if it was running say in winter? I really like the idea of total control over the environment and yes sealed and a co2 burner and a dehumidifier would be the route i would want to go down eventually - but one of the main benefits would be that the mini split would look unassuming on the outside of the property - to me its all about masking those heat emissions into something that looks as if it was meant to be there in the first place

if anyone has any experience with this i would like to hear from you...

to answer your question , yes you can cool bare bulbs with AC but its easier/cost less to cool a room that has air cooled lights , theres lots of pros and cons . i dont know the btu ratio and i dont have exp. with mini spilts or sealed . i have been reseraching. when i run a sealed room with mini spilt using 1000's i will be aircooling , besides then your AC doest have to work so hard . cooling 2400watts in your situation , im guessing a 24,500btu unit would do the job with room to expand i havent seen any mini split units under 24k btu

Whitewidow2, here is a good article for you to read: http://www.cannabisculture.com/articles/3368.html

With a controlled environment grow you will need approximately 3500 btus for every 1000 watt light fixture. Keep in mind this is not a hard number as other variables will cause that number to have to be adjusted up or down.

they make higher btu's than that. The highest i have seen is 48,000 BTU (4 Ton). Anyway i know some growers in cali and vegas who have used invincible-electronics.com. They were telling me the people there are very knowledgeable about mini splits since thats all they sell. They have the BEST PRICES around so im told. So you should look them up and call them if you have any questions or are lookin for a mini split. Good luck.

UMMM, I can keep 3, 1000 watt lights at whatever temps I want with a 24,000 btu unit. I own an a/c company. I can get complete systems you can install yourself.

Hello,

If you use a full sealed room with no in no out. Do not forget to add co2 generator since you re plants will need lot of co2.

For the reflector hood. I would def use them. They are a great add on to put in a room and trust me, like someone mentioned you re BILL will be lower.

Have a good day!

The answer to your question is "yes". Nothing in the sealed room would survive, but it would be cool in there so long as the a/c BTUs equal or exceed the BTUs put off by the light(s). Excluding any outside variables.

They work. They work just fine.
Brand wise - get a Mitsubishi or get problems faster.

Air cooled hoods will go a long way to making a mini split more effective.
Even with water cooling a Co2 gen will add copious amounts of heat and humidity when it runs...

I have to say this here. If you are going down the road of a stand alone building to grow in - Hands down it's going to be a normal Central AC/furnace that will work the best and cost less in the long run.
There is a place in Florida that sells central and Mini Splits at wholesale prices......

Here read this post. It has a link to the wholesale to the public heating and cooling place

are you talking only 600 watts ? then a 5k btu only will be over kill a small window unit will cool it just fine for a open bulb inface a 5000 btu will cool two 1000 watt open reflector .
