Why We Don’t Build The Troughs Off The Ground
This is why we don’t build the troughs “up off the ground to avoid bending over when working”. We know “not having to bend over when working” is important; we’re going to explain why you don’t have to when using our systems, even with your troughs on the ground.
The first reason we don’t build them up off the ground is that they cost four times as much when you do so. This is because the troughs weigh a ton for every 8 feet when full of water, and you can’t just lift that much weight off the ground with a couple of 2X4’s. You need a solid, well-built structure with a ¾-inch plywood bottom that doesn’t collapse; and that kind of structure is expensive!
The second reason is that we just don’t bend over when we work, and our troughs are directly on the ground. Well, we do bend over once when we put the rafts with baby plants into one end of our 80-foot long troughs, and once more when we bend over to pick the rafts up out of the other end to harvest them when the plants in them are mature. We never bend over to work on the rafts when they’re in the middle of the troughs! We do all our planting of seeds in a shade structure, then transfer them to the sprouting tables, then to the rafts in the system troughs. All this work is done standing up or sitting, whichever is most comfortable for the worker.
When it’s time to harvest, we take the rafts which are at the other end of our 80-foot long troughs into the harvesting area, where we harvest the vegetables off them while standing up in the shade, listening to the boom box and talking with our friends. Because we take 1/5 or so of the rafts out of the troughs each time we harvest, there’s room for the rest of the rafts in the trough to move down towards the “harvest end” of the trough by that much. They move so easily that you just push them with a single finger as you put the newly planted rafts in at the “planting end” of the troughs. When all your newly planted rafts are in the troughs, your troughs are again full, and all the rafts will move again in this manner the next time you harvest.
