I was thinking of digging out a hole in the ground and building a box to go in the hole the box will have a hinged lid and will accommodate the res. then use maybe a 30 gallon garbage can as the grow cell which will have at least 2 inch drainage out the bottom and cascading back to the res. I already use a filter bag on the pump in the res indoors and am anticipating alot of algae out doors... hoping the res being subterranean will keep the temps down a lil, as a chiller is not in the budget. I think ebb n flow might get a lil to hot in between cycles so i'm contemplating doing a constant recirc. w/ a crap load of o2 bubbling. I'm just curious to see what can be accomplished in hydro with free light, and air

thanks again Stinky
