Hello Everyone. I'm new to RIU. However I do have knowledge of the plant and I have started to understand this system with the help of everyone. Here is my plan or situation. The reason I'm posting is because I'm looking for information related to my exact cicumstances. The first thing is the purchasing of the system. I like the idea of the Sentine Modular Ebb and Grow which can be converted into drain to waste and complete drainage. However the 600 price tag does not include a rez. Thats okay though.Money isnt the issue the best system is what Im seeking. The room is twenty feet long by 4 feet wide. Can I go three wide with buckets that have the Power Plant?Or do they really need to be 10" Apart from eachother? Ideally I would like to have 30 pots for Power Plant and 16 pots for another strain??? Any comments or Questions?
