70 watt sodium haloide/T-12 flour gro-lux lighting combo?

I was wondering for my plants now about 5 days into flowering can i expect a decent yield with my current lighting of x4 t-12 gro-lux fluorescents and to add to the spectrum a 70 watt hps haloide light, or should just scrap that idea and go with a 400 watt HPS system

dig a hole

Here is what I am working with/on. I have two plants about waist high, both flowering, and I use sunlight plus this light to supplement. I think the light from various spectrum will do a good job, as long as you concentrate on the red (2700) during flowering. I'm sure we'd all love a couple of thousand watters, running off our new solar power system, and it is a nice dream, but for now, I just want a little bud to ease the pain. I am betting I'll get a good crop, on minimal $.
