FarmVille Double Mastery on now through February 16

If you're looking to quickly master some crops in FarmVille - perhaps the new crops released in the Greenhouse feature, or the limited edition Cupid Corn crop - but don't want to spend Farm Cash activating your instant-grow Biplane, you'll be happy to know that Zynga has just launched the latest round of Double Mastery in the game, as a way to say Happy Valentine's Day to each and every player.

For those that aren't familiar with how Double Mastery works in FarmVille, it's incredibly simple. If you harvest a normal crop, without a bushel activated, you'll receive two points of mastery for each one square of a crop that you harvest. If you do activate a bushel, you'll then gain three points of mastery for a single square, allowing you to rack up those mastery points in no time flat!

This round of Double Mastery will last from now until February 16 at 9:00 PST, so make sure to use this time wisely to master as many crops / as much of a crop as you can in that time.
