the reason why i am asking these questions is becasue flood and drain seems to me to be the least hassle of all hydropnic systems as in very low maintainance. how much do you think i would cost to build a 3x3 flood and drain system yourself (red. flood table, pump,gromets and all) and would it be better in your opinion to build it yourself other then buying a system becasue i see these 3x3 tables and there expensive and they look so simple.
