Air Cooled Advice

[mellofello]

Wanting some sun system air cooled hoods myself, 4 of their magnum xxl hoods will probably only just fit they are so huge! Can't be having the same problems I had last year with the heat so its air cooled or switching to 400s for me.

peace

Adding the Mantis reflector onto the cool tube is really easy.

If you just remove the lamp housing from the mantis shade you are left with purely the reflector.

Now if you remove the small reflector from the inside of the cooltube (around £60) and work out a way of attaching the mantis, normally wire and metal tape does the trick. And you then have an aircool mantis. To a degree.

Thanks Herb, this might be a way to do it. Only thing is, with 6" spigotts on those tubes a 6" RVK may not blow enough down the tube to cool 5 x 600 watts. Have you done this yourself? It wouyld be interesting to hear from someone who's gone down this route

Iv done 3x600 on a 6" fan and cool tubes anymore and your pushing it IMHO if you upgrade to a 8" and use a reducer it will do 5 like a piece of piss.

use 8" ducting to connected to the 1st tube, then 6" duct to connect the rest of the tubes- out vent hole.

p.s
Id try to use the double cool tubes that will save half the light being eat up by the ducting they are 800mm long, the small tubes eat 1/2 the light in the ducting they cost about £10 more than the 400mm so you would save a bit in the long run.

Thanks yet again, Nut. If I can push enough air through an 8" fan with a reducer through five of these Cool Tubes that seems the way to go. Especially if I can fit them to my Mantis reflectors - I just love the spread they give.

Just one thing though - these 800mm cooltubes take two bulbs. Thats way too much light on such an area for me and, presumably, two ballasts per tube as well.

Can they run with just one bulb inside?

yes they can run with just 1 if you want. The thing with cool tubes they give a shit spread of light because of the metal collar's on the ends even if you have a reflector over them, the 800mm tube will cover a nice 6x4 area perfect @ 50 watts per square foot don't try and skimp on how much light your putting down on an area you can grow the same amount of bud with the same watts above in a 4x4 tent at 75 watts per square foot, skimping on the light will yield less = loads of leaf and twigs with fook all on the lower 1/2 of the plant.

The way i grow and if you look at some of the bigger grows they run 600s @ 3x3 and 1000s in 4x4 area = buds you can drive a truck over and stay in shape not the fluffy scraggly shite that average wattage gardens produce.

Yeah go for 8inch reduced down to 6 that will easily run 5 * 600. I have run 8 in a line like this.

And if you can fit them in go for the 800 or 1m cooltubes as said. They will give a better forward / back spread. Just be ware that if you remove one of the light fittings from a dual tube you may need to tape over any holes it leaves in the collar.

I use supernova air cooled reflectors. I pull the cool air in from outside and pass it through the hoods and back out again without ever coming into contact with the grow room air. I use a separate filter fan and outlet for extraction. I prefer the parabolic hoods to the tubes as I think it gives you a much more efficient spread of light.

Temperatures can still be an issue though in the height of the summer.
