Well if youre only going to grow 3 or 4 plants (which is more than enough for two people for a good few months), then youll do fine with a small 250w or 400w MH and HPS (Metal Halide and High Pressure Sodium - MH for vegging and HPS for flowering) bulb, maybe even a few CFLs would do the trick. If yer hubbie is really, really paranoid about growing, then start with some CFLs because they give off hardly any heat and use a negligible amount of electricity. This will ease his mind, knowing that the helicopters and electric board WILL NOT be able to find the grow, unless you TELL PEOPLE. After a few months, (when hes too stoned to understand anything lol) swap the CFLs for a HPS bulb. CFLs are fine for vegging, and OK for flowering, but get a HPS for flowering and youll notice a definite increase in yield and potency.

Alternatively, just grow behind his back and then in 3 months surprise him by throwing a pound of the finest homegrown in his face.
