Organic Nutrients for Healthy Food Grown Indoors
Indoor gardening is very popular, and especially so for growing food in inhospitable climates or where soil is poor or not available. If you are trying to grow food indoors, you will want to grow it organically. Organically grown food requires that all fertilizers be of organic quality, and this is the case for hydroponic gardening as well. Hydroponic nutrients can also be organic nutrients, and can help you to grow wonderful organic vegetables and fruits in indoor gardening environments.
If you are growing plants in containers using soil as a medium, by the time you water the plant ten times, all of the nutrients from the soil have washed out of the container. This is why it is vital to fertilize container-grown plants.
It is even more crucial with growing plants with hydroponics, because they are grown in a soilless medium and receive no nutrition at all from the medium. The plants rely on the gardener to supply them with plant food, which in hydroponics is often reffered to as nutrient.
Plant food can be synthetic, or man-made, or organic, and derived from plant or animal materials. Chemical-based gardening tends to focus on immediate results that can be achieved through the use of synthetic chemicals. However, evidence suggests that toxins in the chemicals can be harmful to humans, and thus as a result there is a movement toward eating organically grown foods.
Organic nutrients are used to help you feed your hydroponically grown plants without relying on chemicals. Organic plant nutrients, such as Foxfarm or Botanicare nutrients, are intended to be released more slowly than chemical fertilizers, and offer plants a steady supply of organic nutrients.
Organic plant nutrients contain macronutrients of nitrogen, phosphorus and potassium, sulfur, calcium and magnesium, along with micronutrients of iron, molybdenum, boron, copper, manganese, zinc and chlorine. Because hydroponic plants are often grown in water, the hydroponic nutrients are dissolved in the water in which the roots of the plants lie.
There are many different types of organic nutrients for hydroponics, including Botanicare nutrients, and they each offer a slightly different recipe of nutrients for specific purposes. Botanicare nutrients offer formulas of organic plant nutrients that help your plants achieve healthy vegetation, more and larger fruits and vegetables, and can even increase the oil, sugar, vitamin and mineral contents of the fruits and vegetables grown using Botanicare nutrients.
Organic nutrients can be aided by media conditioners. These help the roots more easily access the nutrients in the medium, as well as allow moisture to penetrate the medium more efficiently.
Growing your own food organically, with organic fertilizers, will help you to consume healthier foods, and they are fun to grow as well.

Does an experiment on whether radishes grow better hydroponically or in soil sound high school level?
You need to be looking ata more focussed question than simply hydroponics versus soil. Perhaps you could look at using greenhouse hydroponic seedlings for transplant starts versus a greenhouse seedling grown in soil-less potting medium for transplant starts. Do the transplants have the same ability to move to a garden plot?

This could be a question of root structure differences grown in artificial hydroponic substrates versus potting medium. Does the root environment control the growth of root hairs? Do some plants grow root hairs differently suspended in a hydroponic medium from when they are grown in soil but receiving the same nutrients in both cases. The formation of root hairs is influenced, in part, by the amount of O2 available. Air has ~21% O2 and is present in the soil. Hydroponics must offer the same percent O2 to support plants adapted for normal loam. Then there is the type of nutrient in solution. The Dominion organic site claims the salts in synthetic fertilizers deters the growth of root hairs. Many people note a difference in root hairs from a cutting started in a glass of water versus flowing hydroponics versus potting medium started cuttings.
