Rosy Cheeks said:I don't want to be condescending to new ideas and alternative solutions, it's all great, but... those dual bulb hoods are far from an ideal solution IMO. First of all, you want to spread your light source(s) as evenly as possible over a designated area. Meaning that if you - as an example - have a 6'X6' area with two 600w bulbs as lighting, then you should place those two lights in a way that the entire canopy gets more or less the same amount of lumens. This is not going to happen if those two bulbs are lumped together, even with the best of reflectors. You will have to space out between the bulbs in order to get a good light spread.
Secondly, HID bulbs produce a lot of heat, and that heat is the main factor that reduces the life span of a bulb. Two bulbs stuck together that close increases heat tear and wear, the bulbs actually kill eachother, and to counter that you'll have to boost ventilation.
The nose to nose solution is the best one if you have to squeeze two bulbs into one hood, because the bulbs radiate sideways, and the light/heat output is minimal at the nose.
The side by side solution is simply not recommendable as a set-up. Sorry.
Oh, and $800 for a hood is pure robbery, unless it comes fully equipped with bulbs, ventilation system, carbon scrubbers and a high class hooker that gives great body oil massage. Seems like just about everyone wants to stick their hands deep into growers' pockets nowadays.
Rosy Cheeks said:. I believe Texas Kid's priority is the dual spectrum (HPS and MH light together) which is why he lumped the lights together, but I would personally still place them end to end and rather than side by side and rotate the plants around the lights regularly. It's doable on a small surface.
To tell you honestly, I think a single 600w light on a 3X3.5 area is enough. If you want a superior light spectrum, use a 600w bulb with reinforced blue spectrum, and use a digital ballast (that will 'up' your light output to what a 800w - 900w bulb would produce with a magnetic ballast) to get that extra yield you're dreaming of.
cheapstar said:Howdy, You guys have me inspired! 4x4 Homebox with 400watt HPS Can fan 175cfm and can 2600 filter. Beats the crap out of any closet as far as removing heat. I'm usually totally cheap, but these things are really cool. It took about 5 minutes to put up and with the cost of Panda film it seems like a bargain, when you factor your time and effort into the equation.
A 2x2 econojet fits in with plenty of room left over for a few plants in soil spread around the corners. The temps amazingly, are within 2 to 4 degrees from the room its in. Awesome. I'm want in!

I use an E&F table (made for the nutramist, as a standard 3x3 table will not fit inside the tent). under the table, are two 14Gal Rubbermaid containers, one sitting inside the other. If i fill the inner container, up to the height of the outer container, i end up with 10Gal.
My water pump is overkill at 600gph, but considering I have it pumping through an inline particle filter, and the container level is almost 2 feet above the pump, I like the bigger pump. I also constantly aerate the reservoir with an airstone and airpump.
I use 100% chunky coco, normally in 2.5-3gal square pots. water 15min 3x per light period.
I use a sunspot 6 reflector, with a 600w Super Hortilux, powered by an elux electronic ballast. I also lined the inside of the tent with Ultraflect reflective material. The ultraflect is simlar to mylar, only easyer to work with, and is something like 97% refective. I never wore sunglasses while looking in the tent, until i hung the ultrafect.
I cool everything with a Stanley Blower fan, sitting on top of the tent.
I also have two fans to circulate air, sitting in adjacent corners, blowing across the tent, at container height.
I think its something like 7.6A when everything is running.
I love my tent.
