Along with water, hydroponics plant nutrients, CO2 and oxygen, grow lights is the key basic component, required by plants to live. Providing additional light is necessary for indoor gardening. Furthermore, light should resemble the sunlight as much as possible. The major concern with other types of lights is that they do not produce light in the appropriate spectrum, required by plants.

Being the most efficient bulbs, HPS bulbs are commonly used by gardeners. Producing light in red and yellow spectrum, light generated by high pressure sodium lamps resembles the natural sunlight during autumn. Due to this peculiarity, HPS light is the best for promoting plants blooming. However, some plants may react negatively to this type of light, growing with oblong stem, etc. To address that issue, new HPS bulbs with color correction have been developed. For example, Son Argo feature properly balanced light spectrum, which suits perfectly for the needs of indoor gardening.

High pressure sodium grow lamps are made of a semi-transparent ceramic arc tube, filled with a mixture of sodium, mercury, and xenon. The arc tube is placed into the protective outer glass shield, similarly to metal halide bulbs. The power ranges of HPS bulbs vary from 35w to 1000w, while the most popular are 250w, 400w, 600w and 1000w.

HPS bulbs are more durable in comparison with MH bulbs: they can be replaced once every 24 months. Though HPS grow lights lose their brightness slowly, in order to keep the brightness at the steady level, it is still recommended to replace the bulb within the specified period.

Among the brand new types of grow lights are sulfur lights, which are said to feature extremely high brightness and effectiveness. However, these bulbs are still rare on the market in view of the high price, so it is early to evaluate their practical value for those gardeners, for whom indoor hydroponics growing remains a hobby.

The urban gardener asked:


One can enjoy hydroponics gardening any season of the year, but it is especially rewarding during the cold and dark winter days. Being a type of indoor gardening, this system implies growing of plants in a special growing medium, supplied with nutrient solution, instead of soil. Similarly to other indoor gardening methods, with hydroponics gardening it is necessary to use grow lights, which allow plants to grow, make food and reproduce themselves through flowers or fruits. For this purpose HID lights are commonly used. There are several types of HID or high-intensity discharge lights: for example, metal halide grow lights and HPS grow lights. Every HID light requires digital ballast, which is necessary in order to control electrical current within the lamp, and thus provide its seamless functioning. Supplying light with a reflector is highly recommended as well, since it allows pointing the light in proper direction and increasing the light, produced by the bulb itself. Other type of grow lights are cost-effective and lightweight LED lights, where light-emitting diodes are used to produce light in colors beneficial for keeping up plant growth. The use of any of these lamps is highly effective for hydroponics growing.

Metal halide lamps contain aluminum arc tube, filled with argon, mercury and a variety of specific metals. It is a set of different metals that provide a particular color of the light, produced by the lamp. The argon gas works to start a lamp, when electric current is introduced at the electrodes on either end inside the arc tube. Under the effect of electric current mercury and metals start to vaporize and the light is produced. The key benefit of these lamps is that being small in size they produce a significant amount of light.

HPS grow lights, also known as high-pressure sodium lights, also have an aluminum arc tube inside, similarly to metal halide lights. However, the filling of the tubes is different: in case of HPS there are sodium, mercury, and the Xenon gas inside. Both metal halide lights and HPS lights require ballast for stabilizing electric current and providing smooth performance.

LED grow lights are small, but work very efficiently providing a lot of bright light. In general, they are similar to the lights, used for decorating Christmas tree. The light is produced when electric current moves between the two crystals inside a diode, which works as semi-conductor. Furthermore, LED grow lights usually have a reflector and a lens to direct the light where it is needed.

 Along with being cost effective and energy saving, there are multiple different color spectrums to choose among in order to suit specific plants needs in the best way. So, irrespectively to what type of grow light you choose, it will work accurately and provide effective growth of your indoor plants.  

The urban gardener asked:


Along with water,  hydroponics plant nutrients, Co2 and oxygen, grow lights is the key basic component, required by plants to live. Providing additional light is necessary for indoor gardening. Furthermore, light should resemble the sunlight as much as possible. In order to achieve that goal several types of lights are used: incandescent, fluorescent, high intensity discharge or HID lamps and sulfur lights. While there are many other types of lighting, only the mentioned above are recommended for indoor gardening. The major concern with other types of lights is that they do not produce light in the appropriate spectrum, required by plants.

Though typical widely used incandescent lamps fit any ordinary light socket, this type of lighting is considered to be the least effective in lighting your garden in comparison with other types of lighting. Incandescent lights produce light in the red spectrum; that is why such lamps are commonly covered with a blue coating in order to increase the amount of blue spectrum in the produced light. In general, incandescent lights are considered to be poor options for indoor gardening needs.

In comparison with incandescent lamps, fluorescent lights produce more light with lower energy consumption. However, the light, produced by fluorescent lamps, is not intensive enough and cannot penetrate more than 6” – 8”. Light, produced by fluorescent lamps, is usually simply insufficient to provide normal growing of plants, vegetables and flowers. The only application, where it is possible to use fluorescent light, is growing seedlings, cuttings, or some particular plants with low light requirements, such as orchids.

High intensity discharge lights, also known as HID lights, are currently the most effective lights for indoor gardening. Metal halide (MH) and high pressure sodium (HPS) grow lamps are two major types of HID lights. Each type produces light in a particular range: for example, metal halide lights generate blue spectrum light similar to the full summer sun, and high pressure sodium lights produce light in red and yellow spectrum, resembling the autumn sunlight. 

Though high pressure sodium lamps usually are more expensive (by about 10%-20%) than metal halide lamps, they are more durable with extended lifecycle. Besides, HPS lights feature higher lumen output (97-150 lumens per watt consumed) and lose only about 5% of their brightness after one year of use (for comparison, MH bulbs produce about 70-115 lumens per watt and  lose up to 15-20% of their initial brightness within a year). 

Irrespectively to the particular type of lighting in use, it is recommended to replace lights on the timely manner: MH bulbs – after 12-18 months, and HPS bulbs – after 24 months of work. Basically, metal halide lamps is the more preferred type of lighting for plants, when they grow, and high pressure sodium lamps suit best for flowering plants. However, the discussion on which type of lighting is best is still open among gardeners. Each type of lights offers its own advantages, as well as disadvantages, so it is often a matter of personal choice, preferences, growing environment and needs. The scope of this article is to provide plain information on the available types of lighting for indoor hydroponic gardening, while leaving readers enough space for personal decisions on which product to prefer.  By the way, recently a new type of lights appeared. The so-called conversion systems allow switching between MH and HPS lights when it is necessary simply by changing the bulb. Though this type of lighting offers certain benefits, conversion systems are still pretty expensive. More information on particular types of HID grow lights used in hydroponics systems will be provided in the next set of hydroponics guides.

Key Facts on Hydroponics

Hydroponic plants do not require soil to grow in. They use different growing media instead. All the required nutrients are supplied through nutrient solution. Hydroponic system allows cultivation of plants, irrespectively to climate and environmental condition. Hydroponic system allows increasing the density of plants significantly (up to 3 times higher in comparison with traditional soil gardens). It may be surprising but hydroponic plants consume considerable less water than those, growing in soil. Since soil is not used in hydroponic systems, there is no need to worry about crops rotation. Hydroponic plants are healthier, because there are no or very little risks for them to get infected by parasites, living in soil. Hydroponic gardening does not depend on seasons of the year. You can grow plants and gather harvest all year round.

Hydroponics in the Present

Thanks to many technological achievements and innovations, hydroponic growing has already become much more effective, convenient and affordable. Plastic, used for manufacturing of hydroponic equipment, such as plumbing products, fittings, growing pots and containers, etc., made it possible to lower the cost of hydroponic systems significantly.

Multiple electronic devices, such as pumps, timers and monitors, have made hydroponic growing a fully automated process. Furthermore, the hydroponic plants themselves have evolved significantly, ensuring high yield results even if used under the most extreme environmental conditions, for example, at the submarines.

Hydroponics in the Future

The next goal of hydroponics developers is to make indoor gardening eco-friendly and more energy-saving. In this regard, current achievements in the development of solar heating systems look very promising. On the other hand, current innovations open new opportunities for designing new growing light systems with higher lumen output, better spectrum profile and lower electricity consumption. In the long run, hydroponic systems may allow increasing the amount of grown plants to completely satisfy the needs of people in food products, without using additional natural resources and soil.

Furthermore, maybe in the nearest future hydroponic systems, which have already been tested in space on the space stations, will even become another valuable step in the space exploration by the humans.

What is Hydroponic Gardening

These days, when the humanity faces many challenges, associated with natural resources depletion, bad ecology and many health problems, stemming out of the wrong food choices, it is, perhaps, the best time ever to return to natural ways of producing food for the sake of our own and our planet.

It was a common practice for our ancestors to grow fruits, vegetables, herbs and flowers for their own needs. Nowadays, the natural way of growing plants reappears with hydroponics as the particular technique, which makes plant cultivation possible even in urban areas without the use of soil. With more and more people involved, hydroponic gardening develops rapidly these days. Irrespectively to whether it is your hobby or professional activity, indoor gardening brings significant benefits for all.

The definition of hydroponics

Hydroponics most often refers to the science of growing plants (vegetables, herbs, flowers) without the use of soil. Plants are cultivated on a special growing medium, and all the nutrients, required for growing, are supplied via specially formulated nutrient solution. The primary task of any growing medium, used in hydroponic gardens, is to support plants’ roots along with retaining water. There are many books on hydroponic gardening, so if you would need to expand your knowledge in this field, please browse our Literature section or the online library for further information on hydroponics.

I always been interested in vertical gardening, I personally think that it’s a unique and aesthetic way of gardening and decoration. I just want to ask…

a. What do you think of vertical gardening?
b. Have you ever tried vertical gardening?
c. Do you prefer indoor or outdoor vertical gardening?

Thanks for answering!

Indoor gardening is not an extremely difficult hobby, but it does require a small learning curve. Usually, with time and experience, one begins to learn from their mistakes and form a better understanding of the kind of delicate care and maintenance required when it comes to gardening indoors. But if you’d like some general advice to start you off on the right path, here is a list of invaluable tips that you can immediately use to improve the quality of your garden.

First of all, make sure that you purchase pots that are the correct size for the plants you plan on growing. Some plants grow to be very large in size, much larger than anticipated. When you only have seeds to go by, sometimes it’s easy to misjudge the actual size of the plant once it reaches full growth. It’s also a good practical tip to select pots that match the color and style of your home. You’ll find much more pleasure in an indoor garden that is aesthetically pleasing and blends in with the rest of its surroundings.

It is very important to place your plants directly in the sunlight. Otherwise, they might crane towards the source of light and grow crooked. It’s also recommended to turn and rotate your indoor gardening plants on occasion. This will guarantee that all sections of the plant receive the right amount of sunlight. Obviously, without sunlight, your plants will not be able to grow to their fullest potential.

If your home or apartment doesn’t get a lot of sun light, try placing your plants outside for several hours each morning.

Remember to regularly water your plants. It sounds obvious but it’s remarkably easy to forget to do this on a daily basis. Only give the plants as much water as they need – over-watering is just as bad as not watering them at all. Make sure that the water is not too cold or too hot ; room temperature is just right. Try watering them at the same time every day. Associate it with a common activity, like watering after breakfast or after your morning jog.

Another indoor gardening tip you might find useful is to keep your windows open as much as possible. The fresh air is important to the healthy development of your plants. In addition, make sure your home has clear ventilation and is not stuffy or dry, and that the temperature is kept at an average of 70 degrees during the daytime and 60 degrees during the night.

Utilizing all of these tips will ensure that your indoor gardening efforts pay off. A lot of people attempt indoor gardening only to be left a few months later with dried, withering plants and an ugly mess to clean up. It is not terribly difficult to grow healthy, strong fruits and vegetables indoors. I’m sure that with a bit of practice and common sense, you’ll become a pro in no time at all. Just remember: lots of sunlight, fresh water on a regular basis, fresh air, and the right temperature.

Mary Hanna asked:


Eventually we are all given a house plant either as a gift or a plant from someone who is moving and can’t take their plants with them, instantly giving you the basis for indoor gardening. Many times if you don’t know how to care for it the plant will wither and die. Other times people start to care for the plant and suddenly become avid gardeners.

Indoor gardens are similar to outdoor gardens, it’s just that you are caring for plants in your home instead of in your garden. A big plus to indoor gardening is that it can be enjoyed by people that live in the cities with no access to land. It is also a joyful hobby for people that are confined indoors. The real bonus is that they are healthy for us. Basically plants take in carbon dioxide and turn it into oxygen (photosynthesis) thereby purifying the air that we breath. So you have attractive plants with added benefits.

Indoor gardens are ideal for people that live in hard, cold climates or for someone who lives in a climate that gets searingly hot. With an indoor garden the gardener can manipulate the environment so that their plants thrive. If it is dreary, cold and grey wouldn’t it be delightful to have gorgeous plants sprinkled around your home that not only add beauty but cheerfulness too?

After choosing the plants you wish to grow you must choose a container for it. You can opt for a small plant that can be placed on a counter or windowsill. Even a large evergreen in a big pot can be placed next to your door or in a sunny spot in the corner. You must make a plan for your indoor garden. Figure out where you want to place your indoor garden so you will know how much space you have for the plants. Once this is done you can choose the container and the plants you wish to grow. Don’t forget to research the plants needs, like watering, sunlight and food before you go to the nursery center.

Once you have gathered all of your material you can start planting and arranging your indoor garden in your home. When arranging your garden be sure to put plant that needs bright sun near a window. Plants that just need indirect light should be put in a more comfortable spot of low or indirect sun for them. If you get this wrong you will be throwing out your plants and buying new ones.

Don’t overlook planting an indoor herb garden especially if you like to cook. Herbs needs are four to six hours of sun per day and loose easily drained soil. They are pretty plants and will add zip to your meals.

If you have pets carefully choose your plants. Pets and plants must be able to cohabitate in your home peacefully. Some plants are toxic to animals. You have to be sure that your animal and the plant can live together. For instance, a tall plant may be seen as a scratching tool by cats or even a litter box. Cats have been known to wrap themselves around larger plants and snuggle in the warm dirt. Sometimes this can disturb the roots. One way to beat this is to put ornamental rocks or crushed seashells right on top of the soil.

You can have an indoor garden and enjoy all of the benefits of beautiful plants. Just do some research either at you local nursery or on the internet. What are you waiting for? Start planting.

Happy Indoor Garden!

Indoor gardening is a popular hobby, and one that can actually improve your decor and your health. Glossy green living plants are an unbeatable decorating accessory, whether you favor the bold statement a snake plant makes or the ethereal lightness of an asparagus fern. By surrounding yourself with healthy green plants, you oxygenate your living environment and gain more energy.

Grow Houseplants Organically

You can do some organic indoor gardening with houseplants. Growing organically means you don’t use chemical pesticides, herbicides, or fertilizers in your gardening routine. Organic indoor gardening also means not using genetically modified seeds, cuttings, or other elements.

Indoor Gardening The Organic Way

If you’re serious about indoor organic gardening, you might want to purchase Indoor Gardening the Organic Way: How to Create a Natural and Sustaining Environment for Your Houseplants, by Julie Bawden Davis.

The beginning of the book explains how houseplants are grown and shipped to your local garden center. Young house plants are fed the equivalent of a fast food diet to pump them up so they’ll look good in the garden center. When you bring your new house plants home, they may have a bit of a chemical fertilizer hangover at first. Be patient with them, and soon they will become accustomed to an organic lifestyle.

Organic Fertilizers

The best organic fertilizer is homemade compost. Even if you live in an apartment, you can make organic compost for gardening indoors.

Use a coffee can or another metallic container with a tight fitting lid. Make a few ventilation holes around the side of the coffee can with a nail or a drill. Fill the can with alternating layers of crisp, dry ingredients and wet ingredients.

For the crisp, dry ingredients, use dry leaves if you have access to them. Otherwise, you can use shredded newspaper or crumpled up paper bags.

For the wet ingredients, you can use raw vegetable scraps nothing with oil or butter on it and coffee grounds.

Keeping the compost can indoors will heat the compost up fast and help process it quickly. You can get the compost to make itself more quickly by stirring it periodically.

When one coffee can is full, start another. Turn the first can upside down every day to mix the ingredients and keep the compost cooking. Soon the first can will be full of rich, crumbly compost the key to indoor organic gardening.

Mix a little bit of compost in with your plants’ soil to provide long-lasting nutrients. You can grow almost any houseplant with this indoor organic gardening trick.
