...greenhouses? I need to find some kind of plant, preferably a type of flower that will be done growing in 2 months or less. Or I need a plant/flower that will show a definite stage of growing quickly. Any ideas? If so, can you also tell me how to manage it, the soil it grows best in, the climate it's used to, etc. It's for a school science fair. Thank you! Please be sure to answer my 2 main questions! Also, does being in a pot or container of any sort affect anything?

Brassica rapa grows very fast and is ideal for science experiments. Sunflowers grow fast too and in just three days you will witness amazing growth. Yes, greenhouses to make plants grow faster and fuller as it enhances the suns rays. Yes, the potted plant has more nutrient-rich soil. The three primary ingredients are nitrogen, phosphorus, and potassium. There are also numerous micro-ingredients and lesser important nutrients.
