thanks alot fletch sounds simpler then my idea. Great to hear from the inventor himself.Ok been busy but jumping on. The best way on these is to add a drain valve on the smaller side of the top as low as possible. You use the rubber grommets and regular drain valves availiable online or at hydro stores. The grommet goes in the hole seas the edges then you force the drain end into the rubber which is a water tight seal.It accepts a hose on the out side which can be as long as you need. Put the hose ina bucket or sink or drain open the valve and drain.Close the valve and refill. Simple takes 10 minutes to swap res water out for new...
