Well, you kinda need your hps just because fluorescent light doesn't penetrate foliage as well, but you might want to side light with fluorescents to help light lower bud sites. BTW cool light means from the blue spectrum, & warm light means from the red.
---- We're not legal here either. We have mmj, but its the shittiest medical laws I've ever heard. I'm not becoming a guinea pig for a teaching hospital so they can 'study' me. Cant they understand, if you don't feel good the last thing you need is to travel for over an hour, sit on uncomfortable waiting room chairs for over an hour, then be poked & prodded where you hurt, wait an hour or more in those uncomfortable chairs again untill medical transport comes back for you, & end all this with that long ride again!

Know what you mean about the cool kids thing! I'm a few months shy of 60, & now what I hear is, I can't sell pot to YOU! You know my grandmother! Urghhh.....

Getting busted depends upon your area. They only mess with you here if you're a trouble maker, or your flaunting your transaction out in public. I think country cops would rather you stay home & be peaceful than out in public drunk & belligerent. From what I hear, city cops are a whole different species. So your best answer to that question would come from someone familar with your area.

You already know how to grow plants & keep them alive & healthy. All you really need now is to learn how pot behaves. You've already learned it can get big enough to push the roof off your house if you let it! LOL! Do that again & we'll start calling you jungle Jim! So do a lot of reading, especially before you go to the hardware store, as you may already have what you need. Have fun Jungle Jim! & don't blow the roof off the house!
