Well I have a question...I heard that plants growing too close to each other could cause mold or something..Now if hydroponics are suppose to increase what you would get when growing in soil doesnt that mean the plants would be even bigger? I'm asking this because I think I might buy this...http://www.hhydro.com/cgi-bin/hhydro/HH00465.html but it looks like the plants will be too close together :P.
