A 70w HPS should be adequate provided you are only growing 1 plant.

I need some more info. Hydro or soil? How big is the room? How big are the plants? How many do you have?

I would supplement the lighting with soft white 42 watt cfl's if you cannot get a larger HPS when you go into flowering. The 6500k won't do any good, and I am not so sure about plant lights.

The 6500 is good for veg. When you flower you will need the red spectrum intead of the blue (Around 3000k) Maybe if you can get another 70 watt hps, I dont know. I would also vent the room to get temps down a bit, 93 is a bit high I think.

That would be a question for someone that uses HPS, I am using all CFL's right now. Next time I am going 250 or 400w hps if I can keep the heat down. Those need ballasts that are separate from the lights, but I don't know about the smaller ones.

As for the temps, I am in the same boat. I can get it cooler, I just have to watch how low the temps get.

What I did was this: I hooked 2 fans up to one plug, and one fan up to another. During lights on, all three run. During lights out, I run 2, or 1 depending on temps.

can i get a bigger hps bulb to go in the 7o w fixture

No. The wattage of the ballast must correspond to the wattage of the bulb.

Compact Fluorescent Light. Cheap, use very little wattage, and available in a few different spectrum's. You just have to keep them close to the plants, as the light dissipates very fast. I am running 16-26w(100w) in a 4x5x6' space.
