Experiment for growing tomato plants in winter?

Question by vibz7: Experiment for growing tomato plants in winter?
So for a class i have to do an experiment on how different fertilizers affect plant growth. Right now its the middle of winter so the weather isnt on my side. Because I have to grow them indoors I have a couple questions…. What type of seeds would do the best in this experiment? Since the water is a constant how much water is needed? Because its inside do I need a special type of light? And I need three different types of fertilizer which would be best? And what the cost would be?

  1. You won’t get enough sun indoors even though you’ll get enough heat. The lighting cost would be ludicrous. Like the other answerer said tomatoes need a lot of light and heat. You would need a greenhouse to do it right with tomatoes. Try finding a winter vegetable instead. Radishes are the easiest to grow, or you can also try beets or brocolli. If you aren’t allowed to grow them outdoors then find an herb that tolerates partial shade; it will say on the label. Or lettuce or spinach could work near a sunny window indoors; they don’t need as much light.

    For fertilizers there are major nutrients, minor nutrients (aka micronutrients) and decomposed plant material (such as earthworm castings). The 3 major nutrients are nitrogen, phosphorous and potassium, shown as the 3 numbers on the front (# – # – #). A basic fertilizer should at least have those 3. You could pick 3 fertilizers that include some or all of those things and see how the plants compare. By picking one that has little or none of a major nutrient the effects will be much more obvious, or you can look for more subtle effects of being with or without the minor nutrients or decomposed plant material.
