4" aircooled hoods and where to find them

[summitoker]

I am looking for a 4 inch air cooled hood....the size of the space is 26x39. I have found very few options that use a 4 inch flange, most are 6 or bigger. It looks like the yieldmaster is my best option but if anybody has links to something i have not found it would be most appreciated

 

[K.J]

I too would like to find out if there are any good ones out there.

The original Super Sun is nice.
It has a 4" flange option.
Higher quality but more expensive than the Yield Master.
Here is the distributor page:

Reflectors lose a good bit of light with two 6" holes in the reflective material.

Original super sun it is thank you dongle69

 

[vinnythebat]

are the original ss's vents on the sides?

Super Sun 1 is a great 4" reflector. It puts out a really nice light spread as well.

are the original ss's vents on the sides?

Yes. Long sides instead of at each end. I use on and like it a lot. Even the holes have reflective material over them.

Depends on where the ports are. Lamps throw little, if any, light forward or back. Point an HID at the wall and it throws a black spot. With ports to the sides, you'll lose some light. Ports on the ends lose little.

Well there are two that I can think off at the momoent.One being the super sun 1 and the other being the SunGro,

I say get the yeild master with 6" flanges and run 6" ducting from the hood to your 4" inline centrifugal.The bigger ducting will not only cut down on duct losses from static pressure etc. but it will also allow the air to flow more freely and therefore quiet down the noise of the air wooshing around in the ducting.

Except we are not talking about a bare bulb.
We are talking about light bouncing around in a reflector.
It makes a pretty big difference.
My light meter agrees.
Try looking into the open port of a reflector that has the ducting removed.
Major light spillage.
Even with a bare bulb I have never seen a light throw a black spot.

i think it'd b worth it with co2 and you dont have to worry about burning your plants

I've never seen an HID throw anything else. Here, have a black spot. Due to the light the camera had to shoot through, the spot appears far lighter than it really is. It's true darkness is more similar to the shadow cast by the door handle.


Will a hole release light? Sure it will. But, the light lost forward and aft is the most bounced, least useful, weakest light the lamp produces. Light through the sides is direct light, the most powerful light the lamp produces.

Everything's a tradeoff. My freezer makes my grows secret and safe but, it means no more 20 foot trees. Double steel wall construction won't allow it. I say sacrificing 20 foot trees to avoid 20 years in prison is a good trade.

Sacrificing the least useful light a lamp produces to increase overall lamp strength from lowering the lamps may be a trade many are willing to make. So little light is thrown forward and back that turning the lamp perpendicular to the length of the grow will allow you to increase the effective footprint while lowering the lamp. Placing lamp in the traditional parallel setting requires hanging the lamp far higher to achieve the same coverage because forward and back light is just that weak. Increased penetration is useless when it penetrates nothing but air.

I think you are missing something.
We are all taking about air cooled hoods.
All of them allow you to not worry about burning plants, etc.
The original Super Sun included.
It has less light leak compared to many hoods with 6" holes because, as growmeds pointed out, the duct holes have reflective material over them, but still allow for air cooling.

hey summit toker the sun systems sungro can be vented with 4" ports, as well.
thats a pretty nifty reflector, much like the SS1.

the yeild masters don't have the reflective inserts on all 4 sides - only 2. the sungrow & ss1 both have complete 4 walls of the pebbley goodness.

the only downside with buying the reflectors with the 4" ports is that you have to buy the glass lens & port fittings seperately. shouldn;t cost you an arm and a leg, but maybe another $30. Which, if you get what you want, is worth paying for.

good luck

 

[Greyskull]

another option would be a hydrofarm daystar (not the daystar AC... the original daystar).
definately not as bright as a sungrow or ss1 in my experience... but another option for you to check out.

 

[dongle69]

Here, have a black spot.

Yes, and look at the huge circle of light around that black spot.
All coming from the end of the bulb.
That is just from the low wattage bulb you have posted.
Even bigger and brighter with more popular wattage bulbs like 600 and 1000.
Free light. Lots of it.
Your ductwork has no use for it, but your plants do.
What is not to like about that?
Is there a downside to more light being reflected onto your plants?
I don't understand the resistance from freezerboy and mrred.
