Greenhouse Lighting

Being able to control the outdoor lighting in your garden, your greenhouse or your allotment should be viewed as just as important as being able to control temperature, ventilation and humidity. Outdoor lighting can be used to provide you with more time in the greenhouse or it can be used to affect the growth of your plants.
Greenhouse lighting is designed to provide good general illumination - allowing you to work in your greenhouse when it's dark outside. Also known as supplementary lighting, greenhosue lighting can also be used to increase day length during those parts of the year when it starts to get dark earlier - the winter and spring months.
Grow lighting is designed specifically to help the growth of your plants and is often used to 'force' plants to flower out of season. This makes grow lighting more sophisticated than supplementary lighting, with the quality of light produced by grow lights being more closely controlled than supplementary lighting in your greenhouse.

Grow Lighting
Grow Lighting can be used to help produce bumper crops. Where natural daylight is not always available or when you want to boost the natural daylight to encourage quicker growth, then you would choose to install a grow light system. If you raise your plants indoors - where they have limited if any access to natural daylight - then grow lighting becomes very important. It will prevent your plants from becoming drawn, leggy and weak and it can also be used to encourage some plants to flower.

We've chosen our range of grow lights based on their efficiency in use to give you the best results. We've got systems that have polished reflectors for even light distribution or systems where you can exchange the lamps throughout the year for even, healthy plant growth. All the systems come with reflector, ballast and lamp, with replacement bulbs also in stock - please note, the Professional Grow Lighting system lets you select you own lamps, metal halide or high pressure sodium, with the lamps being interchangeable in the same power pack and reflector.

Plant Lighting
Light is essential for plant growth. Light makes it possible for plants to carry out photosynthesis which provides energy for plants to grow. Plant lighting - sometimes called grow lighting - is an artificial light source, normally electric, that enables you to ensure your plants get sufficient light for healthy growth.

You can divide plant growth into two key periods - vegetative and flowering. For healthy vegetative growth plants need to be exposed to blue spectrum light. For successful flowering plants need red/orange spectrum light. You can therefore select your lighting system based on what you want to grow.

Metal Halide Bulbs(also known as MH lights) provide a blue light that promotes green growth, shortening internode spacing and preventing 'leggy' plants.

High Pressure Sodium Bulbs (also known as HPS lights) provide a red light to promote flowering growth in the later stages of plant growth.

Although you can choose to use one type of light throughout the whole period of plant growth, for the best results we recommend the use of MH lights at the beginning of plant growth and swop to HPS lights as the plants mature to encourage lots of flowers.

The other option is to choose a plant lighting that provides full spectrum light, like the Mercury Lighting System.

Greenhouse Lighting
Greenhouse lighting can be divided into two mains types - lighting that allows you to work in the greenhouse when it's dark outside and lighting that promotes plant growth.

Our General Purpose Lighting is ideal for producing a light that you can work under - and having a horticultural lamp means that it doesn't damage plant growth. The fluorescent tube used in the General Purpose Light is a full-spectrum bulb, producing a balance of cool and warm light as it designed to replicate natural light. This type of light is great for seedlings as well as most plants - so for simply extending daylight hours our General Purpose Light is a good choice.

We stock a wide range of 'grow lighting' - lighting systems that are designed to affect plant growth. These include traditional mercury lighting systems, sodium lighting and the more modern Metal Halide and High Pressure Sodium lighting systems.

When deciding on the type of lighting system to install in your greenhouse, it's important to note that the duration of light is important for healthy plant growth. You shouldn't leave lights on 24/7 as all plants need some time in the dark - when it's dark plants respirate, an important part of the growth process. The balance between light and dark periods is therefore important, affecting the growth rate as well as the setting of buds and fruit. Plants can be divided into three different types depending on their preferred length of time in daylight - short-day, long-day or day-neutral.

Short-day plants are those that will thrive on less than 12 hours of light per day - e.g. chrysanthemums, begonias. Long-day plants require at least 14- 18 hours of light each day. Most vegetables and garden flowers fall into this category - if they don't receive sufficient time in the light they will become drawn and leggy. Day-neutral plants like to have between 8-12 hours of light per day - e.g. African violets, foliage plants, geraniums.

Artificial Lighting
Artificial lighting can be used for two different purposes - to supplement natural light or to replace natural light.
When growing plants indoors it can be difficult to provide them with sufficient natural light for healthy growth. Artificial lights enable you to grow healthy plants in any spot in the home not just on a windowsill. You can visibly improve the health of plants in dim corners by providing them with 4-6 hours of artificial light every day. Our Bio Green Lumino lighting system is ideal for providing artificial light in the home. And by simply placing your plants on top of a mirror or white sheet of paper you can increase the light available as it reflects the light back onto your plants.
For plants that can't tolerate direct sunlight, artificial lighting is ideal as it produces a light that is less harsh on plants as sunlight. And for plants which require moderate to low light, artificial lighting can be used as the sole source of light.
For plants that receive no natural light, you can decide when to make light available to your plants - most plants will need 12 - 16 hours of artificial light per day but it doesn't matter when plants receive that light. When you are supplementing natural light turn on the artificial light to coincide with the natural light. Just remember that plants require less light in the winter months, so reduce the amount of light available to them at that time of year.
Garden Lighting
We stock a range of garden lighting, in both traditional and contemporary designs, both for practical lighting and decorative displays. All our garden lights are solar powered - easy to install and with no running costs, solar lighting is the simplest way to effectively light your garden. Our range of garden lights includes security lights, border lights, post lights, table lights, hanging lights and light strings. So whether you're looking to light a driveway or pathway, need spotlights or garden lanterns you're sure to find the garden lighting you need from within our range.
High Pressure Sodium Lighting
High Pressure Sodium Lighting Bulbs are normally used to promote flowering and fruiting. The orange-red light that high Pressure Sodium Bulbs produce makes plants think that autumn is on its way, so stimulating them to produce flowers and fruit.
By using High Pressure Sodium Lights in combination with Metal Halide Lamps you are able to provide your plants with the perfect growing conditions in regards to light. This is one of the reasons that we stock the Professional Grow Lighting system which allows you to exchange High Pressure Sodium Lamps and Metal Halide Lamps throughout the year.
We always recommend using High Pressure Sodium Lights with Metal Halide Lamps. If using High Pressure Sodium Lights exclusively, you need to ensure your plants will also receive sufficient natural daylight otherwise plants will become drawn and leggy. So either High Pressure Sodium Lights in a greenhouse setting where good natural light is available or use with Professional Grow Lighting system where the fittings allow you to exchange the High Pressure Sodium Lights for Metal Halide Lamps depending on the stage of plant growth.
Indoor Plant Lighting
When your house plants are suffering from lack of light, artificial indoor plant lighting may be the solution. You can use indoor plant lighting to supplement natural daylight or to replace it completely. Many house plants will positively flourish is provided with artificial lighting - African violets, begonias, bromeliads, cyclamen all of which need bright light in order to flower - whilst many foliage plants will also flourish under artificial lighting - aloe vera, spider plants etc.

Lighting will affect the growth of your plants in two different ways: by the amount of light they receive - so the number of hours of light on your plants - and by the intensity of light - so the different levels of light, e.g. in natural light the intensity will change between full sun to full shade.

The amount ofl indoor plant lighting is important when using artificial lights indoors for your plants. Foliage and flowering plants will need between 12 to 16 hours of light per day to flourish. Ideally provide your plants with light at the same time every day - and remember that as much as needing light, plants also need at least 8 hours of total darkness per day. Also be aware that plants grown under artificial light will dry out more quickly, so will need more water than plants growing in natural light.

LIghting Controls
Lighting Controls are important when you are growing plants with the aid of artificial light. You need to be able to control the length of time the lights are on as well as controlling the time of day when they come on and go off. This need for control is critical when it comes to healthy plant growth, as plants not only need light to grow, they also need time in the dark to remain healthy.
Although the length of time plants need can vary between flowering and foliage plants - with foliage plants needing less light than flowering plants - you are looking at between 12 to 16 hours of light per day. Your plants will also need at least 8 hours of total darkness per day. Ideally the light and dark periods should be provided at the same time every day.
The easiest way to control artificial lighting in this way is to use a timer. You will need to use a timer that is suitable for high wattage lighting systems as a standard timer would not be suitable - our Lighting Timer Unit lighting control is designed for these systems and can be used to control up to two systems.
Mercury Lighting
Mercury Lighting systems are ideal for use in a greenhouse as they produce a type of light that is good for plant growth. Mercury lights are also energy efficient and long lasting - mercury lights waste very little energy in heat (compared to other lighting systems) and use up to 75% less energy than an ordinary light bulb yet last 10 times longer.

A Mercury light bulb produces light by running electricity through argon gas and a small amount of mercury vapour. The mercury bulb (or lamp) produces an intense bluish light, resulting in a relatively well-balanced, high intensity light. Sunlight contains the full spectrum of light - red through yellow to blue and violet. Plants use the full spectrum of light for photosynthesis, although red and blue light is the most important. Red light stimulates vegetative growth and flowering but if a plant gets too much red light it will become tall and spindly. Blue light regulates plant growth, making it ideal for growing foliage plants and short, stocky seedlings.

A mercury lighting system that includes a polished reflector will ensure uniform illumination, whilst the intensity of light that a plant receives is determined by the wattage of the light bulb and how close the plant is to the light. Plants differ in their needs for light intensity - generally plants native to tropical jungles or shady forests do not require as much light as those plants native to dry, sunny climates.

Metal Halide Lighting
Metal Halide Lights are considered to be the best choice for serious indoor gardeners. Metal Halide lights emit an intense, bluish-white light that is excellent for growing plants - plants will flourish under this type of lighting, with foliage remaining green and vigorous, whilst internode spacing is reduced resulting in stocky, strong plants.

Metal Halide Lights are also economical to run - they generally produce twice the amount of light as a fluorescent bulb yet use the same amount of energy.

Outdoor Lighting
All weather Lighting for Outdoors in a range of practical and decorative designs designed to make it simple for you to be creative with your garden lighting. With so many people now using their gardens as an extension of their living space, Lighting for Outdoors has become more and more important. Lighting for Outdoors can be used to enhance features within your garden - a simple spot light highlighting a shrub or tree, fountain or statue will add extra dimension to your garden. Lighting for Outdoors can be used to increase home security - such as our Solar Security Lightswith built in motion detection features - or to add atmosphere into your garden using our more decorative lights - such as the Galaxy Wind Spinner.
Solar Garden Lighting
Solar Garden lighting is the easiest way to add light into your garden. With no cables and no batteries, solar lights use the natural energy from the sun and convert it into the power your solar lights need. And you don't need to have long, hot summer days to charge the lights - today's super efficient solar panels are just as effective in cooler, cloudier conditions. There are a wide range of benefits of using solar lighting in your garden, rather than traditional, low voltage lighting and here we list some of the major benefits.
Cost is an important factor when using lighting in your garden. Traditional lighting needs an electricity supply and it can prove costly to have power professionally installed in your garden. As well as costs for wiring, traditional lights will add additional costs to your electricity bill, and if you forget to turn the lights off you'll be paying to illuminate your garden all night. Solar lights need no wiring - so there are no installation costs - and, powered by the sun, there are no running costs associated with solar lighting.
New technology has made solar lights bright especially compared to earlier models of solar lights. New solar lights use light-emitting diode bulbs (LEDs) that require very little power to work - so will produce bright light for their size. These LED bulbs are also good as they should never need replacing (they have a typical life of 300,000 hours).
Solar Garden Lighting can be installed in minutes. With no wiring required, you can place solar lights in your garden exactly where you want them, even in places electric lights would be difficult to install - in trees or along fences for example. And solar string lights make it easy for you to decorate hedges or walls.
Battery Powered Garden Lighting
Quickly and easily create subtle or statement lighting schemes on your garden with our selection of battery powered lights. The main benefit of battery powered lights compared to mains or solar powered lighting is the ease of use. There is no troublesome wiring required, no need for power sockets or direct sunlight - this means you can use these lights anywhere in your garden.

Because mains power is not required (so you don't need to pay a qualified electrician to install mains power and you aren't adding to your electricity bill) these battery powered lights are an affordable way to decorate your garden. To ensure batteries are not drained too quickly the lights we offer are either motion activated or have a built in timer so you don't end up lighting your garden all night and using more battery power than you need to.

Battery powered lights are also one of the safest outdoor lights available. There is no risk from a mains current, the lights run at an extremely low voltage and the LED bulbs don't generate any heat. In addition, as these lights require no wiring they are an ideal option for families with young children or pets as there are no wires to trip over!

The brightness of battery powered lights is affected by the number of batteries used to power the lights and the number of lights. The higher the number of batteries and the lower the number of lights, the brighter the lights will be - this is why the decorative string lights have 10 lights per string and are powered by three AA batteries which ensure the lights are beautifully bright.
