Here's a description from a seed site.

"White Rhino is an excellent cross of White Widow and a powerful Indica strain. It is very high in THC which makes it good for medical use. White Rhino has a sweet, slightly hashy taste, ideal for bonging. Due to the Indica cross, White Rhino is denser and shorter than White Widow, with very white crystals. White Rhino seeds are excellent for medical marijuana applications."

I'll be honest...i received a few clones as a gift and i didn't really research the details. so that cut and paste answer is the best i can do right now! anyone else ever grow it? any more info, tips, or tricks?

thanks!
