Desk Lamp Hydroponic Indoor Herb Garden Kit

These lights have been around for years, and they are an economical bulb to run. One other main advantage is they run cool and can be placed very close to the top of plants with no fear of burning. However, this plus point is also highlighting one downside of these bulbs. The light they give out isn’t strong enough to penetrate past plants outer foliage or leaves.

What is hydroponics?

Plants grow through a process called photosynthesis, in which they use sunlight and a chemical inside their leaves called chlorophyll to convert carbon dioxide (a gas in the air) and water into glucose (a type of sugar) and oxygen. Write that out chemically and you get this equation:

6CO2 + 6H2O → C6H12O6 + 6O2

There's no mention of "soil" anywhere in there—and that's all the proof you need that plants can grow without it. What they do need is water and nutrients, both easily obtained from the soil. But if they can get these things somewhere else—say, by standing with their roots in a nutrient-rich solution—they can do without soil altogether. That's the basic principle behind hydroponics. In theory, the word "hydroponics" means growing plants in water (from two Greek words meaning "water" and "toil"), but because you can grow plants without actually standing them in water, most people define the word to mean growing plants without using soil.
