Ok so i just ordered my Tent it is 8x4x6.8" tall, I also got a nice carbon filter and 430cfm inline fan, will order an addition intake fan when it is up and running My question is how much light do i really need in this tent to cover it to the best of its ability, i currently have a 430w HPS and was thinking about getting another and just having those 2 spread out in the tent, but was also considering buying either 2 new 600w Hps/Mh or possibly even getting LED(viparspectra's)900w. Thanks in advnace for any input, picture below is the tent

Best bang for your buck right now is cmh (ceramic metal halide) i just picked up a duel output 630w ballast with 2 bulbs and reflectors for about 5 bills. Would light that tent up pretty good and only pull about 700w from the wall. The company i got them from is sun spectra. My setup is pictured on their instagram.

What I got specifically to light up a tent that size is a 6' light rail to move a 1000W HPS back and forth to cover it when it's full of plants. I've got 400W lights I can use when it's only half full then just switch to the 1000 when I can cover the whole floor. Using it now in my grow room and now I want another light rail. :)

:peace:

hmmm had not thought of that, how does exhausting a 1000w do when its on a rail same as stationary i assume just gotta give it some flex in the ducting.

those cmh's look good, i'd like to try them myself.
i run a 4x4 tent, and it takes a 550 cfm phresh filter hooked to a 440 cfm fan to keep the odor under control, you might want to step up a little for an area twice that size.
i find one 600 watt hps covers the 4x4 well, and the 600 is the most efficient of the hps. two would be better than one 1000 watt, and end up costing you within pennies of the same.
not to start a whole new debate, but i'm experimenting with leds, both quantum boards and cobs, you might want to look into that before you invest a lot into h.i.d. lighting, good savings and you only need the exhaust for odor, not heat

Yes considering 2 600w viperspecters

you can do so much better, go to the led forums here and look at the members who are also advertisers, i'm sure you can get a good diy kit for the price of those vipers

I would use 2 600W or equivalent.
600W is good for about 15 sq ft. so two is good for about 30
Yours is 32 sq ft, I think it is close enough to stretch.
Alternatively, 1K on a light mover rail.

I'm not using an air-cooled hood. I have one but it restricts the light to a more downward path when I want it to spread out more to cover a wider area. A cool tube reflector would probably work well too but I don't have one of those.

An oscillating fan blows through the canopy and helps cool the light too while temp/RH controls maintain an even room temp +/- 2 degrees C.
