Precision Hydration Apparatus

     Hi! It is my pleasure to present to you… Precision Hydration Apparatus!      One of my hobbies is indoor gardening and I have noticed that available automated hydration devices are rather imprecise, using only one pump and timed watering. If you have plants placed at different heights there could be a big difference in how much water goes to which pot and one watering duration setting applies to all the plants you are trying to water. I tried to use mini valves on hoses but that was a mess.      The concept of my “apparatus”(lol) is simple: it measures the weight of the water tank at the preset time, and activates a pump that sends water from the tank to the plant until the weights read a pre-programmed value. So let’s say the apparatus reaches preprogrammed time for action 13HR 00MM 00SS, it weighs that there is 730 grams of water in the tank. Then from the preprogrammed record, corresponding to the time, it reads how much water it should pump, let’s say -100grams. It activates a designated pump, one out of four, and pumps water until the weight reads 630 grams and then it stops. It can also operate in a different mode, instead of placing a water tank on the scale you can place a plant pot to monitor its weight, and pump four different liquids into the pot, let’s say water, nutrient A, nutrient B, until pot receives preprogrammed amount of liquid. Just make sure that the pot has a container on the bottom to prevent overflowing.      About implementation: apparatus can drive up to four pumps. Each of them of course you can use for more than one pot, but the amount of water will be shared. Pumps activate sequentially. There is nothing really that in theory stops you for programming it to activate more than one pump at the time, but there is again issue of how much water goes where, if two pumps are active at the same time, and you need to pump let’s say 200 grams of water, there is no way to ensure that they will pump equal amounts, each exactly 100 grams.
