Lighting Question

I have a cool cab from sunlight sheds. it 72" tall x 36" wide x 18" deep. i just bought a 600w hid lighting system for it and when i installed it the temps went up to 120f with the door closed. I had a LED light setup and the temps stayed around 85f. I was thinking that if i got a window unit a/c and ran ducting from it into the cab it might help a little but i am not sure. I was also going to run the ducting into the duct that blow air through my lighting hood. Any suggestions would be greatly appreciated as I just paid a lot of money for the lighting system and cant use it unless i can get the temps down.

holy shit dude 120F IS friggin hot!too damn hot to grow weed. Good ventilation is they key to growing and getting good yields etc. There should be a way to vent the cab so do the ductwork like yopu said and an in-line fan and exhasut the got air out and bring cool air in. Idk what the sunlight cab looks like but you should be able to vent/exhaqust the heat out of the cab and into a diff room or wherever possible. Do you still have the Led? If its possible to leave the door open then do that bc the reason its getting so hot in there is that theres no other means of fresh air getting to your gurls! A good ventilation system is the key mang and you sond like yopur on the right track with installing some ductwork/get a fan/ and the a/c unit you mentioned will def help lower your temps/just will raise your elec bill:(

Lets get a handle on this before this gets out of hand.

First question, what is the lowest temp you can maintain the room where your cabinet is?

I hope there are no english teachers here.

It's in my grage. The temp stays around 85 in there. The cab has two intake fans and one exhaust fan in it now. Must not be no wear enough. All the inline fans I see are so expensive so hopefully the air comin out the a/c will be enough.

I hope it works

You're putting an 600w heater in an encolose space with the coolest air being 85*, you would be lucky to maintain 90*.

IMO it is not going to be successful. You need AC and I only move Air I don't make it cool. Hopefully someone with portable AC experience can help you.

Yes I do still have the leds, and if I leave the door open bugs take over so I can't dothat. As for the other comment I was trying to compare cold air to volume of air moved in price. A a/c unit cost 300 and a 500 vfm fan is 300. So I am not sure which way to go. Cold air or volume of air. Thanks for all the input.

If the air temp at source is 85* you can not get your room any cooler (it will never get closeto 85* more like 95* as you have seen) without removing heat, you do this with an AC unit.

I do plan on getting a window a/c unit in the grage to cool down the overall temp of the grage. I was just wanting to know if Jerry rigging duct work coming of one side of the a/c and going into the grow box itself, would that be enough to bring the temps down to where they need to be or would I still need to get one of those expensive 440 cfm inline fans to bring the temps down. I just know that not matter what I need to find a way to get them down or I paid a lot of money for something I can't use, meaning my brand new 600w hid kit.

I have not done it myself but there is a UK grower on here that did just that and it worked great. Let me look for the link. Maybe J remembers it and has it.

Thanks for all the input and the link. I am going to try it out and hope for the best. I post comment about it later. Thanks again man.

No matter how much air you move, it will not get lower than what's outside the grow space. If your intake is sucking in 85* air, it will stay at 85*.
On the other hand, an AC unit will LOWER that temperature to that which you are looking for. No brainer really

He's right and I have no brain.

I am going to go with an ac but my main concern is if I put a ac in there and it drops the temp of the garage down to 70 that only drops the inside box temp down to 100f. So I still have to get the temp in the box down even more. They say around 75-80. I think. So hopefully routing cold air from the ac to the box will get it where it needs to be. Hopefully.
