Hmmm...I have three 



 and have only done one 

 at a time.   
For me, it takes a lot of time hunting for the right things for our lil' Secret Buddy so, I can't imagine tackling two, let alone three.
 
 
Remember...the GE runs every three months so, your lil' Ollie-Pop (love his name!

) wouldn't have that long to wait till the next GE and possibly have some more grow-time, too...just a thought!
