You don't get what noon day tropical sun does for you. Do it. They're not that expensive and they are well worth what you will get out of them. Put a goddamn light up that has got CMH bulbs in it.

Years ago I researched the various wave lengths that metal halide and sodium lamps put out and then I came upon CMH. Dramatically different. In those days it was a special mail order catalog item. I bought that s*** before it became popular. It really makes a huge difference.

So while it is a cannabis growing bulb there's a reason for that. It hits all the wavelengths that real sunlight will hit you if you were hanging out on a tropical beach at noon. And that s*** makes a difference when you are simply feeling blah.

Do it.
