winta - been reading all the good info on the farm and doing some planning for a grow room... i should have sometime started in near future but i can tell you it will be a DWC setup... also there seems to be a lot of good people on here and thats why i joined the farm... i'm a computer science major that spends most of the time in our company labs dealing with scientist and engineer, so anytime i see something the 1st that i think of i can make it better... well, we will see...
