Oh man, that a tough one. So much cool stuff going on in the auto world. I harvested my first Stone Dragon about a month ago and am really impressed (have 6 more of them going at the moment). I will have to allow those who have grown a lot more than me to answer
BTW, what are you looking for as far as effect, yield, etc.? Might help others provide better ideas for you.
not worried so much about yield ....the effect i like is when it takes an hour to put on socks because i can't tell which is the right and left sock...when i finally find the left sock i realize the socks are different colors so i stay home and giggle for a while?
