Last night I came up with a trick. I can't carry 40lbs on my back or shoulders anymore, I'm rather limited nowadays. What also REALLY kills me is having to constantly bend over or remaining bent or crouched. With long hair that can be difficult to control in the wind tunnel I've turned my flower room into, I had to find a solution to reaching all the way back to the girls in the rear for watering.
Enter Piece of PVC with Elbow, and the Plastic Milk Jug. Just cut the jug so that you have the handle and spout, and, ok, I duct taped it to the PVC but gluing and taping might be better, but in any event, there ya go. Just put one end where you need the feed to end up, you've got a generously sized funnel that helps keep splashes where they belong, no more bending over except to check and see that it's in the right place, et voila.
Next year it's gonna be automation time. Fertigation seems to be the best solution to ensuring all girls get an equal measure.
