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.

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.
Depending on how you set up your grow, it can take anywhere from 2 months to 6 months or more to grow a marijuana plant from a seedling to the point where the plant is ready to harvest. Some methods, such as growing hydroponically indoors, give your flexibility to get a harvested plant in as little as 2-3 months.
