Anyone know how I can exhaust heat out of a 150w sun systems hood? I posted the same question on my thread but I don't get much feedback on it, hope I can get an answer here. I've looked everywhere but can't find any useful information. The hood has no glass cover or hole on the side to add ducting. I have an exhaust fan readily available for this.

Alright sorry but your questions have some missing/misspelled words. Are you wondering if its ok to go from a window to 175w HPS for flowering and if a 175w is enough for one plant? I say if your ready to start growing buds, get it into flowering, going from a window is not gonna do anything drastic. The only thing you havent given is the specs on what your gonna be flowering in as your plants could easily double in size, as far as a 175w being enough, for sure...i grew and flowered 3 plants under a 150 and it came out great.

I have 1 fan blowing at the bulb and one to the plant. I have both cabinet doors open during the day and my house AC at 72 and the temps inside the cab still manage to creep up to 78-80. It gets up to 90 with the doors closed.

What strain? and where you satisfied with the overall quality of your grow with the one 150w?

is the ballast in the hood or remote? if it's in the hood, you can easily make it remote and that'd help some with heat.
i used to just hang my exhaust ducting at the same height as my hood so it'd suck up more of the heat. or cut a hole in the side of the hood and hook it up to some ducting.

Thank you for your reply. The ballast is in the hood like the picture below (I have that exact light) What do you mean by making the ballast remote? I have tried hanging some ducting right next to the light bulb but it made no difference (strange I know). I was actually thinking of cutting a hole on the side and hooking it up to some ducting like you suggested. How easy is it to cut a hole on the hood? and also, do I need to put a piece of tempered glass under the bulb so it traps the heat and it's properly exhausted through the ducting or will it be ok without the glass?

Keep the door open most of the time, if possible. I have a 400W HPS in a 3x3 area and I can keep it at a comfortable 77-80 TOPS with an oscillating fan.

Honestly, don't worry too much bout the 150W. Keep it at least a foot away from the canopy and you're in business! ;)

I currently keep both doors open and also the bedroom door the cabinet is in so all the air circulates around the house. I would like to have the doors closed in case company comes over and also to stop that glow that comes out of my room lol but most importantly when I flower I don't want my house to reek like herb (I have a carbon filter in the cab).

A few days ago I forgot to open the door back up in the morning after the lights came back on and in about an hour or two it got hotter then shit. My seedling tips started to curl up.
:sad:

I had 3 different strains...mazaar i sharif, bubble dust and aurora indica. I was happy with the results although I know there were somethings I coulda done differently to get better results, but im always learning each time I grow.

Hey kaze, do you have any pictures of your yeild...im curious to see how they turned out.
Just finished putting the last harvest in jars last night to finish my cure. After drying I had a total of 3.25 oz. This was a White Widow plant grown under (2) 150s. They flowered for 10 weeks total. Grown in a hybrid drip/ deep water system with Flora 3 part nuets. This is only my 2nd grow and I am pleased with the results.
