my system is going to be very similar to the bubbleponics system shown here http://www.rollitup.org/dwc-bubbleponics/234626-rosemans-diy-bubbleponics-tutorial.html. with a few major difs i will be using hid lighting, i will be using a fish tank that i have witch will almost fit the entire length of the room and be painted black i will be growing about 10 plants in that space untill they can be sexed i estimate the end result will be atleast 4 females, witch i dont mind at all because i have 3 strains to grow and i only want one female from each as i will use each as a mother for clones. i will be doing a very small scale comercial grow hence the need for clones rather than starting each crop from seed. (when i say comercial i mean family friends and my personal friends like good weed witch is not easy to come by or cheap)
