Fair enough, but i would ask yourself if you could handle loosing an entire crop in a matter of days? Something that you spent a month or 2 or 3 working on. When the undercurrent and mpb hit the medi scene they were all the rage because of the super fast growth and you could grow monsters with those systems. Everyone started jumping on the bandwagon. After a ton of hard work and money to set these systems up people would start having problems with there plants and roots. Root rot is the biggest issue you face in hydro of any kind. And once you get it, most people found even with extensive bleaching and cleaning it just came back. All it took for most people was to loose one crop and everything you have gained over the last year vs growing in soiless was out the window and then sum. I dont know anyone still running these systems, everyone i know had them in the garbage after a crop or 2. I was about to build one of these systems for my 24 light room till I started to hear all the problems people were having and people loosing entire crops. So glad i didnt. I would suggest u stick to a soiless mix or try a coco or coco/perlite mix like myself and dial that in and you wont have any need to look at hydro.
