Hydroponics: Soilless Gardening Explained

Hydroponics: Soilless Gardening Explained

Plants need nutrients, air, water, and light with a little warmth to survive. Traditionally these have been provided by soil, but hydroponic techniques allow plants not only to survive but also to thrive by gaining the perfect balance of nutrients from a regulated solution. This book looks at the flood and drain method, drip feed, Nutrient Film Technique, aeroponics, and aquaponics. It offers a detailed examination of nutrient content and the strength of solution, advice on how to grow a variety of plants and how to control pests, a simple-to-follow guide to how to arrange and automate a greenhouse, and step-by-step instruction on how to build your own hydroponic systems. Without the need for stooping or weeding, hydroponics is ideal for anyone with back problems or mobility impairment, and superb for children, who can follow and monitor the plants’ growth.

Hydroponics Gardening with LED Grow Lights

Hydroponics gardening uses grow lights to light the plants properly in order for photosynthesis to occur and for the plants to grow and thrive. Lighting is crucial to every kind of indoor gardening situation, because without adequate light, the plants will be stunted and not grow to their full potential. LED grow lights can be used to good effect in an indoor plant growing situation.

LED refers to light-emitting diode. A diode has two terminals, and it allows current to flow in one direction and not in another. It is a simple semiconductor.

Photons are units of light. Atoms contain photons, and it is the photons that produce light. They produce light when electrons move around and change positions. Electrical current, in an LED lamp, flows across the diode, and when this happens, it causes a change in the movement of the electrons. The positively-charged electrons will move in the opposite direction from the negatively-charged electrons. A semiconductor is made more conductive to electrical flow when free electrons are added to the conductor material, creating negatively charged areas, or when they are taken away, leaving gaps in the chain, and positively charged areas. Electrical current flows over these areas, and it causes the electrons to move. The side effect of all this movement is the production of light.

The color of the light emitted by these types of grow lamps is based on the size of the gap in the electron chain. The gap size affects the frequency of the photon, and this is why it has an impact on the color of the light produced. Low-frequency light produced by an LED light is used to light remote controls for one of many common examples, because it it infrared light.

With hydroponics gardening, the color emitted from grow lights is quite vital to your plants’ health. Young plants at the seedling stage require blue light in order to grow properly. Mature plants, such as a flowering or fruiting plants, require red and orange light in order to get the plants to produce the flowers and fruit that you want. All of this is dependent on the light that you use with your plants. LED lamps come in a wide variety of colors, so it is easy to get the exact grow lamps you need in order to get the results you want from your indoor plants.
The advantage to using LED lights is that they do not get hot as they are in operation, and they also do not have a filament, which you find in incandescent light bulbs, so they often have a longer productive life because of this.

Only Aerobics Give You Energy

The fact is that even if you are into isometrics, isotonics or anaerobics, you still need to do aerobics for overall health and fitness. That is the reason why even body builders with their sculpted biceps and sharply-defined waists are advised to add aerobics to their fitness programme. That is also why specialised books on weight-lifting or abdominals always include running-on-the-spot or stairway climbing to burn off fat.

There is no getting away from the basic truth - that you need oxygen to live to your fullest. Perhaps if the body had been fashioned in a way where it would have been able to store oxygen and release it as required, we wouldn’t have had to exercise. But it is not. ,Its mechanics demand that oxygen be used immediately to create energy. Our natural breathing draws in enough oxygen to create sufficient energy to keep us alive and go through our daily routine. But we need more oxygen to go that extra mile without feeling fatigued. That is where aerobics comes in.

Don’t you want to go that extra, mile? Don’t you want to enjoy your leisure hours without feeling like a bleached whale? Don’t you want to tap your maximum potential? Of course you do!

You want that extra energy. You want to do more than just sit, sleep, move around, eat, digest. You want your life to extend beyond waking up, brushing your teeth, catching the train, climbing into your car, working in your office or at home. Without exercising, you can manage all these activities. Imagine how much more you could do by priming up your cardiovascular system! Essentially, your body is an energy machine. It provides you with energy to get through the day. If you do not service it aerobically, you will begin to feel tired by noon or by evening. As the years roll by, your sedentary body will groan at the thought of any activity beyond the required minimum. And soon you find yourself saying, “I can’t do things like I used to,” or, “After all, I am older.” Right? Absolutely wrong!

If you could measure your stamina in a test tube, you would see its level dropping year after year. Not because it is a natural process of growing old, but due to the unnatural tendency of not replenishing that decreased stamina. Due to disuse, the lungs, heart, muscles and blood vessels lose their tone and elasticity. They cannot process oxygen like they used to. The so-called ageing process is mainly nothing but deterioration through disuse.

The logic of health and fitness is simple:

Your body needs oxygen.

Oxygen racing through every tissue oxidises the fuel and produces energy.

Energy gives you stamina.

To restore the oxygen-processing, energy-producing ability; your body needs regular aerobic activity.

And that aerobic activity should be done 20 to 42 minutes, about four to five times a week.

Fortunately, there are several natural energy-producing activities to choose from. They are:

Walking.

Outdoor jogging.

Indoor inchstepping.

Cycling.

Swimming.

It’s time to move those muscles. It’s time to get fit. In all probability, you are an averagely healthy person with no medical problems.
