From reading your post i can tell that you are apparently doing this to study the plants with perhaps getting the bonus of getting to smoke a lil something in the end right? Where as most of the people on here grow for the sole purpose of smoking it. I believe that if you can envision it you can build it, and if you build it you can probably work the kinks out and make it work. That being said i think that from a cost standpoint your plan seems overly expensive and time consuming. If i understand it you envision a setup where each plant is essentially independent of each other, sounds great till i start to picture your shopping list, separate, fans, pumps, timers, etc. It adds up fast. And i can just imagine the fun of maintaining and changing out all those separate reservoirs. Bloody hell mate i hope you don't have to work for a living cause your setup will demand hours of your time each day. And i wouldn't call a five foot tall plant a "micro grow" it might piss off the pc case growers. And they tend to be an irritable bunch due to the fact that there little setups only seem to be able to get em high every 60+ days, lol, {sorry i'm just kidding, go smoke your 1/8.} It all depends on what your after, If you want science, then do it, If you want bud it's alot easier to copy something someone else has already worked all the kinks out of. I mean i completely get the desire to tinker, but make sure your doing it right. Good luck
