Preheat the grill for 5 minutes. In a medium bowl, use your hands to mix together the mince, Worcestershire sauce, black pepper, garlic salt and onion until the ingredients are evenly distributed. Shape the mixture into hamburger patties. Place the hamburgers on the grill and cook for 7-8 minutes, or until cooked.
In general, tomatoes take around 60 to 90 days to grow and then ripen. In a hydroponic system, because you are providing the plant with the absolute best growing conditions, I would expect this to be sooner, and you should be enjoying your tomatoes within 60 days at the very most.
The larger this reservoir, the more stable and successful your hydroponics system will be. At minimum, each small tomato plant (such as cherry tomato plants) will require 1/2 gallons (1.9 liters) of water, while most, somewhat larger tomato plants will require 1 gallon (3.8L) each.. Decide which type of system to use. There are several varieties of hydroponic systems, and tomatoes can grow well in any of them. The instructions in this section will teach you how to construct an ebb and flow system, which is relatively cheap and easy to build.
