The study aimed to extend the shelf life of lettuce consumption and tackle box with hydroponics plant growing in the gutters. By comparison, keeping boiled eggs, salad vegetables in boxes 4, including boiled eggs cut in half and put it in a zipper bag, clear bag full of leaves and a bag to bag. It can be seen that the salad box, containing boiled eggs cut in half clear zipper bags full of leaves and boiled eggs stored in clear zipper bags have a shelf life of 7 and 11 days, respectively, at a temperature of between 5 to 14 degrees Celsius in the fridge. Because of the respiration of the vegetables boiled egg, the yolk has passed the water with oxygen, thus helping to accelerate the process of breathing, more vegetables and smells. The rot of lettuce box. And comparison of hydroponics to grow vegetables in the same system. (Pump pressure at 30-32 watts) with the new system (pump pressure at 35 watts) due to pipeline blockage caused water to make oxygen in the water and the temperature of the refrigerator to soak the salad box. Lab-grown vegetables hydroponics in the old system to the new system. Pump water pressure at 30-32 watts with 35 watts of power used to pump water pressure to measure the consistency of the manure (EC) and the acidity - alkalinity (pH) in the Strip, but one that is growing consistently. After four to six hours, but in the second trough plant will have a regularly after fertilizing. Adjusting the pH - alkalinity (pH) within two hours by planting lettuce fourth type is Iceberg (Finnegan's), Butter, Head, Rex, Red Oak, Christine and Green Oak. c Christine grown vegetables have a 45 day weight 2.3 4 1.8 and 3.1 kg, respectively, in the new system (in table 2) when fully grown vegetables weight at 45 days 0.5 2.4 0.5 and 0.5 kg, respectively.
