Excess heat needed to be sorted !!

GanjaGazza · Mar 29, 2012

Ok so i am growing in a standard sized wardrobe, and i just switched by babies from a 200cfl to a 400hps and the heat level in the room allready is insaaaaaneeee, this has to sorted out soon but i just wondered what my options are, ive seen alot about both cool tubes and a heat reduction light hood, just wondered what is usually the best and cheapest option, I have a maxibright 400w http://basementlighting.com/Merchant2/merchant.mv?page=1/PROD/MMEGL
are these products usually made compaible with this light, is it a case of one size fits all or finding the appropriate one ?

peronally i'd use a cooltube hooked up to a fan extracting
or air in at bottom hot air out at top using good inline fans.
your ballast and bulb will fit the cooltube. can get for bout £40

well lets see "cheap options" i bought a large desk fan [a normal one you would see on a desk] for 10 bucks at walgreens it was a put-it-together so it was very cheap. Do you live in a cool place? A intake pipe from outside or from any a/c register in the house [if you dont live in a cool area] is a cheap option. I just close the other dampers in the house besides the one i use.

think im gonna get a cool tube and that silver hose and stick it out the window, getting quite hot the last few days !! how long will my plants survive in excess heat what problems may this generate?

Any thing over 95 is not good, keep the doors open or go back to your other lights till you get it sorted. Even a 4" fan in the top will do the trick without the tube.

Dude did you pay that much for that kit? Bit pricey. Basement lighting sell same kit on eBay cheaper. Same shop and everything! Also since judging by being in £ like me your from UK. DO NOT vent hot air out the window! What your doing is illegal here (not knocking it) and best way to stay undetected is not blast out a continual flow of hot air out your window that helicopters can pick up.

You need a bigger fan. I would go for least 6"/400cfm. Don't pull freezing cold air in from a/c. Inlet temps still need to be at least 60F or you will freeze the plants next to the inlet.

I like the think of heat as a thing to be moved/ re-moved. It's easy to only think of the air. But the walls and ceiling are major problem. They get hot and re-radiate, in infrared. A bigger problem, indeed.

For emergency you can hang buckets of ice with a little bit of drain holes in the bottoms. Another bucket under. Ice, to ice water, to removed warm water. As all drunks know

, there is cool air next the floor. Or even better, under the house. Introduce the coldest air you can find. But, a swamp cooler won't work, you need cold dry air.

Another thing is pull air thru your exhaust fan. Don't try to push air in. That adds over-pressure and thus heat. I went to water cooled and all the plumbing hassle to conquer this. And it's still a problem in a bathroom.

Last resort is a good one, also. Add CO2. It helps the plant tolerate the heat into the 90s and increases yield.

i'd go back to the old light until you can control temps.

go back to the old lighting until you get a cooltube. i got a cooltube and a 4 inch fan and filter hooked up to it and its wayy better. a 6 inch would be best but i cant afford a 6 inch and my current 4 inch worked fine.

As I said, Freezing air will reduce your yield, if not kill your plants

I don't see why people say this. There is absolutely no reason to not vent hot air out your window. Its not illegal or suspicious. People vent there ac unites out there windows all the time. Personally I have multiple ac's blowing very hot air out my windows 24/7 when its summer.

I think people are reacting to the stories of people being caught by helicopters reading heat signatures of large grow rooms. The good news is the Supreme Court has decided that is illegal without probable cause or a warrant to use equipment that reads things not visible to the human eye. The bad news is manufacturing probable cause for a warrant isn't all the difficult.

The other issue ofc is scent. Depending on grow size and stage of flowering, that can be an issue for those in densely populated areas. I'm not in a densely populated area, but i bought a phresh filter to test during flowering.

Doer · Mar 30, 2012

Yeah, don't allow freezing air to enter your grow. Good point.

Even the AC drain water can have detectable xxxinoids. Enough to alert a dog, enough for probably cause if in the wrong state/country.

good point. i'm so US-centric its embarrassing. ofc lots of people live in countries that are not under the jurisdiction of the US Supreme Court

[FONT=Tahoma, Calibri, Verdana, Geneva, sans-serif]are you in America? UK this would look extremely odd. No one runs AC's unless grow related.

In the UK this is a very real threat. No warrant, court ruling or any other legal steps are needed to use FLIR. In the UK it's a very very real threat. Blowing hot air out of a cold house in a cold country. Bit strange no?

thats why you dont put the pipe right next to your plant....if its pretty far away by the time it reachs your plant the heat from the lights should of matched or surpassed the amount of cold air. plus considering how far your pipe is running and the fact that a/c registers aren't built to push air through a pipe you dont get THAT much air in the first place. its 80 next to my plant right now shes far from freezing.

Doer · Mar 31, 2012

Yeah, America. England's got norther latitudes and coarser attitudes, it seems. But, on another thread on another forum we were discussing the inventions of England before the USA. Very impressive. With a little more work, even FLIR can be blocked.

But America. The land of the Big A/C and backyard swimming pools that dot toward the horizon. A swimming pool is a gold mine of a heat pump sink, btw.
