I'd be happy to point you to the guide. The Plant Tycoon Guide section of the forum (with lots of useful content) is here, and the mutation guide is here. Don't forget that you can always select the "Forum List" link near the top of the page and scroll down to see every available forum here.

P.S. Many of the links from old posts are now broken, since the update of the forum software changed how those links work. We have fixed some of the most important ones, but there are too many of them for us to repair them all.
