that rotation station wont give u high yeilding plants but it will have many of them so u will get an overall decent ammount from it. i think u would get more from a standstill system. u could buy one of the ebb/flow systems http://www.77hydrostore.com/ebbgrfldrsy.html and u can get a 6 plant site add on, so that 18 4ft plants in the system, thats alot!!u could use a normal cloning machine and use soil for the mums
