Hello everyone I currently have 600w hps in my flowering room with a basic reflector thats comes in the powerplant kit, Ive got a 4" inline extractor fan and 2 pc fans for outake and 1 pc fan and an axial fan for intake aswell as a pc fan cooling the light,
I have doent everything i can think of to lower the temps such as running ducting from the outtake to the light to exhaust the heat but I cant get the temps below 33'c ( door closed) I am thinking of investing in a adjustawing reflector as it has a heat shield wich supposedly helps alot with heat problems Does any one have any experiance with these reflectors, Ive find this 1 on ebay but it seems a bit to good to be true - possibly a cheap rip off http://cgi.ebay.co.uk/Adjust-a-wing-Medium-Reflector-/120596037669?pt=UK_HomeGarden_Garden_PlantsSeedsBulbs_JN

Its a pice of shit....especially if your havin heat problems..does your hood already have 4 in. holes on both sides, just get better fans, suck the air through the hood and blow it out the room

thats what im doing, btw my veg room is within a foot of the flower room so the heat is combined with the 400 in the veg room, are they realy that bad?

I am running a 600w sys too. It is an open hood and my temps fluxuate also. Two things you can do is get an AC unit, maybe a cheap one around $100 bucks or get an enclosed hood. I know you want to go cheap but if you go too cheap then your plants/harvest will show. If I were you try to get an enclosed hood and get a dampner switch for your fan. that way you can turn it up if too hot and turn your fan down if it is too cold. Just a few ideas. Make the sacrafice now or you could possibly kill/stress/hermafrodite your plants!

The grow is located in a stone cellar the floor temps are about 23c outside of the grow room, the exhaust fan has ducting directing it up out of a vent, i currently got 3 white widows 1 cheese 2 cali dreams and 2 unknown afghani's, the flower room is 112cmx155cmx126cm and the light is 60cm from the head of the plants

I don't know where to get an AC unit in the UK but they do have them over there right? I am in the US bro so I can't help you. Maybe your best bet is get an enclosed hood to keep the heat down.

Ive struggled with 100+ temps b4 and found that pointing a fan blowing up at your bulb helps some to keep yhe heat above your plants. Not much but it keeps em from drooping from heat stress. Stone holds in heat and dampness so its going to be next to impossible to lower temps without AC...http://www.puravent.co.uk/

That Adjust-a-Wing reflector will NOT reduce heat in your room though ....You got a pic of your set up ?

I have a feeling you have fans just moving the hot air around rather than directing it anywhere .

You might be better with a Cool Tube .... have a passive ducting sucking air from outside your room... connected to a cooltube ..and your extracter connected to the other side ... Thats the set up i have and it works perfect for me .

I have my fan on just a box standard dimmer switch an i can control the temps pretty well in a very small space .
I will find a diagram of my flow ...

Just a very basic .. Passive air being sucked in and thru the tube and a t-peice connected to my filter and then out to the extractor fan sucking them both ... works a treat :)

cheers for help everyone, my exhaust is fan is located right behind the light so it is drawing out all the hot air sending it through ducting wich expells out a vent to the hallway. Last night i unplugged the light for my veg room and am going to begin 12/12 having the veg room flowering while the flower room is off etc ( i think that was partly cause of the heat) and i have a computer fan cooling the bulb of the 600w hps the top of it is cool enough to put your hand on, technicaly it should be cool ( aswell as on the 400w) I thought the heat shield that is equipped with the adjustawing was meant to be good, ive only read good things about them till now.
And ive heard bad things about cooltubes hot spots etc so please enlighting me plent of + rep to go rnd

One thing that I'm kinda gonna be known for as the person who comments about insulation, Can lower temps massively by itself, trust me had to learn this the hard way. There are many different methods of applying- sheet foam, roll fiberglass, loose fill, and the best thing but little pricey spray foam same stuff as the spray can foam but larger. I used the froth-pak 12 worked to lower temps. hope this can help

Your cheapest fix is to switch to cfls. The 42 watt veg/flower bulbs at 1000 bulbs are only about 3 dollars U.S. each. I had mine under 2 400 watt mh bulbs and switched to cfls when I moved the grow upstairs. If the mh bulbs were better than the cfls, they were not noticeably better.

Another fix might be to rig a carbon scrubber to vent to the outside. This would pull out some of the heat.

carbon filter has arriveed, problem is it fits my 4" ducting but the filter itself is about 9" in diamater and i dont think its going to fit into the short tunnel wich vents up into the hall, also the oppisite end of the fiter to where the ducting connects is sealed off ( i hadnt noticed this before) and was expecting to to have the extractor fan blowing through the ducting into the carbon filter and up out of the vent but this wont work as its sealed and i think the sides will be cover from te walls of the tunnel
