I'm researching techniques about growing, and I think lighting will be a large issue for me, mainly because of my budget.

I was thinking about having a 400W HPS for vegging, along with supplemental full spectrum CFLs for flowering.

HPS grow light kits go for $180+ for the 400W set up, I was curious to know: without any wiring experience, how would one go about making a HPS system?

Is it as easy as purchasing a ballast, or what else is required? Could I get away with something like this: HydroWarehouse Online Hydroponic Superstore for a HPS system?

Thanks for your time!
