Say one of my plants weighed out 250-300 grams wet, what would the dry weight be? Does it cut in half drastically when it dries?

**update**

Ok, I decided to stop being lazy and just Googled that shit. Found a thread on here and most members agreed that you will lose anywhere from 45-70 percent in weight. Bummer, that's quite a bit!

So any of you guys know the real truth behind cops using infrared cameras and other tech., to bust people doing indoor grows? What's your thoughts on this?
