i took two 4-step stringers and built a mini staircase with scrap lumber.i put one 3' windowbox on each stair except the top one. i hid the resivoir under the stairs then it was time to make the water flow, the water went up one side of the stairs into the left side of the top windowbox then when it was filled the tube on the right side of the window box drained down to the next level then it darined to the next level and so on... now to empty the boxes when the pump turned off i created a drainage system i have never seen used before... a small piece of airline tubing at the bottom of the box that drained all the time. as long as more water came into the box than was being drained the box would fill but when the pump stopped the box drained slowly through the tube.
the system worked really well except it was sooooo fragile with all the hoses running in and out of the boxes and i couldnt get to the resivoir to fill it. so this system never grew anything and was dismantled 3 days after construction. but i was not disheartened, i had a nice strong pump i had ordered for it and i had learned from my mistakes. on to hydroponic project #4!
later the wood was painted white and the hoses were installed but this gives some idea of what it looked like.
