A special needs hood?

[papa canna]

I have very specific needs for my hood. I need a hood that has removable glass, with 6 inch holes available for PUNCHOUT. Meaning I need them to remain intact until I decide to punch them out. (I'm only interested in using a single hole) preferably a medium size, but I know im already being picky as it is.

EDIT: I should probably explain a little more. Im deciding whether its more efficient to cool my room from a single opening in a hood or to continue as i am doing it. (an exhaust fan in the return air duct at the top of my bedroom) what do you think is more efficient? A fan at the top of the room getting the heat where it collects, or a fan getting the heat from the other side of the bulb, but then heat would likely build up at the ceiling.

wait, what?

Why don't you just block the holes with 6" plugs from the sheet metal shop?

Seriously though you can attach a damper to one end of the reflector...you'll have to jury rig the damper closed if you do not want airflow through it.

Good Luck and Great Growz!

Just add duct tape

just for efficient reflection. i just didn't want a 6 inch deadzone.

to be a little more basic, i want a hood with optional 6 inch holes because im wondering if it might be more efficient to cool the room by exhausting near the hood. Instead of exhausting near the ceiling which is what im currently doing.

Ok, have you tried googling air-cooled reflectors and seeing if such a thing even exists?

A few come as punch outs. but all the ones that I have seen are ridiculously high priced, and always 8 inches. Which makes my diy job a bit more of a pain. But I think im slowly coming to the realization that it may just be better to exhaust as i currently have it and buy a standard open hood. I have a pair of adjust-a-wings now, but I just feel like they are very inefficient. the front and back side have no reflector so it just kinda throws light wherever.

HMMM...I am a mechanical moron and as such am having a hard time picturing this...could you not get a cool tube and duct it out of the ceiling vent?

You are making this more complex than it is. It IS better to pull the heat exhaust from your light hood than from anywhere else...then just use an oscillating fan to circulate the air in your grow area. Vented reflectors are totally worth the extra dough. While you are at it hook up a filter to kill the smell and an exhaust fan with speed controller makes it easy to dial in temps. Ez breezy

I could. but I dont like cool tubes. they are a cheap fix to an issue and create bad light patterns and hot spots. The point was to keep the hood open. I would be removing the glass from the hood.

I wasn't sure because I planned on using this as an open reflector. it is my intention to remove the glass. I honestly think that the glass hurts more than it helps unless you have big heat issues. (I really dont until a scorching summer, im just trying to be as efficient as possible)

How many watts do you run?

And how big is your grow area? Tent? Room? Cabinet?

 

[Richard Drysift]

If your bulb bursts it will be all over your plants. I doubt you lose much through the glass...it's there for safety but maybe that's not as important as a few more lumens. I don't have heat issues because my vented hood pulls the heat out. My bloom room stays 75 even with added side lighting; if it gets hot in the summer I turn up the speed. If you want efficiency upgrade to LEDs

I pull the heat from my wing reflectors with 6" duct takeoffs attached to them, they work well.

The glass is there to make it a vented hood .

area is roughly 4x4 maybe 5x5 depending on how i space them. In about a 10x10ish bedroom. but i'm probably going to go down in number of plants when i switch to hydro in the fall. Right now i've got 9 in a bedroom under a 600watt.

so rigging some thing near the hood with flexible is helpful?

actually the PAR count as well as uva and uvb lost through the glass are a bit significant.
