Ideal temperature not achieved!

[9KtuFK]

I know the ideal temperature in the growroom is 24-25 Celsius. Iâ??ve just plugged my lamp and the room climbed to 31 Celsius.

What to do ?

Would getting more fan in the room cool things off or do I absolutely need another intake ?

another intake

stronger exhuast... what kind of light are you using?

maybe a cool tube...

BLOW A FAN RIGHT ON THE LIGHT.

^^This.

BLOW A FAN RIGHT ON THE LIGHT.

^^Not this. Sorry, but it won't help much.

FUCK ME ... It finally reached 34 Celcious !!!!!!

I'm using Hotilux super HPS (1000W). I'm getting another intake today so all should be well.

The goal is 24 - 25 celcious right ?

Give your plants some silica blast to protect them. It really helps if you have temp problems.

silica blast?

How big is your area? I have a 1K Hortilux in a 4x3 cabinet and I know how hard it is, but now mine stay under 80F which is about under 23C if I remember the math right. and I may have a few tips as well. What are your ambient temps, meaning in the room with out light on? Also, can you modify the home if need be?

Having run a 1000 watt in an even smaller area, getting rid of the heat can definitely be a problem. But there are a variety of things you can do to rid this issue; unfortunetly they all cost money and some are impractical (to much noise, etc).

First and foremost, I am going to assume that your 1000 watt hood is aircooled (meaning that air is pulled from the hood, over the bulb, and exhausted out of the grow room. If not, well then obviously this is your biggest problem. If you are venting the hood already, consider making sure that you are getting the absolute most efficient power out of the fan. This can include taping the glass (painters tape leaves no residue and can handle the heat) and the seems, using 90 degree hard elbows where your ducting makes a turn, and setting up the fan with the least amount of turns and distance from the hood. In my experience, you need about 300cfm to vent a hood well enough to provide major cooling (ie a 4" inline fan or a speed controlled 6").

With a Cooltube hood, you can get even more efficient airflow over the bulb resulting in even cooler temperatures. Consider insulating your hood as well. Are you using a passive intake or an active intake? Where is your intake being drawn? Your not drawing intake from the same place your exhausting are you? Im my experiments, I found it is much more efficient to use 1 single powerful fan to exhaust in conjunction with a "sealed" room. With a 300-500cfm fan pulling air from a small closet, all you need is a passive intake and youll have a LOT of air moving through.

A circulating fan inside the room will move air around and help with circulating, and having the fan pass over the hood will also help cool it (but only with dissipation). Finally, make sure your ballast is outside of the grow room; this is a large source of heat.

Aside from that, some people just dont have a cold enough intake charge so your fighting a loosing battle. You can get a small portable A/C to help this problem, or some ingenuity concerning where to pull the air from. Some of my friends pull air from the cool basement and vent into the already warm attic.

Finally...if you can afford to have 2 fans, you can seal the light from your room which will cool the most. Pull air from outside the room, through ducting, through the hood, and then out ducting to outside the room. This means that all the air cooling the bulb and hood is cooler then the ambient temp inside the grow room. You then will need a seperate exhaust fan to exhaust the room itself. One 300cfm inline fan will exhaust a room much better then a 150cfm squirrel cage intake and a 200cfm squirrel cage exhaust.
