I like your idea and will do that but what I thought was supposed to happen was that a 'new' plant would eventually grow between two 'different type' plants. Instead of having to always use the mutation liquid.

So, I was hoping that if I first used the liquid to get some new plants, then placed them in a checkerboard pattern that I would get even more new types. After about 3 days of nothing happening at all, I sprayed each with the pollination spray.

Been over a week since I did that and still absolutely nothing.
