Hydroponics is a method of growing plants using mineral nutrient solutions instead of soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel or Rockwool. A variety of techniques exist.Plant physiology researchers discovered in the 19th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a soil. Terrestrial plants may be grown with their roots in the mineral nutrient reservoir but the soil itself is not essential to plant growth. When the soil. Terrestrial plants may be grown with their roots in the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required soil. Terrestrial plants may be grown with their roots in the mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics, but some will do better than others. It is also very easy to do; the activity is often undertaken by very young children with such plants as watercress. Hydroponics is also a standard technique in biology research and teaching and a popular hobby.

White/Blue spectrum 6400k lamp designed for propagation and vegetative stage growing. Envirolites are effective, energy saving, reliable, low heat generating horticultural grow lamps, giving excellent results and lower operating costs for all indoor growers. Plants need light in the correct spectrum, which is proven to be between 400 & 700 Nana Wave, and Envirolites produce high output light in exactly this spectrum. There is no wasted light, unlike HID and HPS lamps which need to be positioned high above the plant to prevent burning, Envirolites do not generate excessive heat and can therefore be used directly over plants. Positioned just 3cm or 4cm above the top of the plant, it gives maximum possible light without burning your plants. Envirolites give 100% PAR (Photosynthetically Active Radiation) high output light and are used successfully for all propagation , vegetative or flowering stages. They are self-ballasting and therefore simple to install or wire, are specifically designed to be energy saving lamps and therefore give much lower operating costs than the alternative, and their high lumen output guarantees long life operation. Lamp also available in 2700k red spectrum designed specifically for flowering stage growing.

For the first time the general public can buy a grow light suitable for domestic growing. Previous to plug and grow, grow lights have only been suitable for commercial growers due to the excessive heat emitted by the lamps, high running costs and complicated setting up procedures. There is a huge market for domestic grow lights due to the unpredictability of the British weather but until now nobody had devised a grow light suitable. The answer is Plug And Grow, a self-ballasting light and reflector kit that provides a simple solution for the domestic grower. Plug And Grow kit can be plugged in directly to a standard mains socket and and it is then ready to emit immediately. It doesn't get excessively hot and uses an energy saving lamp to keep down electricity bills. The possibilities with Plug and Grow are endless and its an exciting time for everyone. We are finally convincing the general public that you can grow vegetables/plants indoors with no natural daylight whatsoever. Just think Growing your own tomatoes in your garage, cucumbers in your cellar, pepper Plants in your patio. There is a huge interest in the 'grow your own' culture presently and Plug And Grow allows you to do just that, without a greenhouse, and without a garden!

Envirolites are self-ballasting lamps and no transformer or ballast is required. They are reliable, easy to install, economical to operate and give exceptional, proven results. Envirolites are intrinsically safe, low heat generating grow lamps<./a> and will not burn your skin if touched by accident or burn your plants, even they are located just 5 or 6 cm above the plant tops, or hung between plants when using our Envirolite Lamp Hangers. Envirolites are ideal for all year round indoor propagation and all growing applications ~ please see our website for details of our reflectors, lamp hangers., E40 Envirolite socket holders etc. If you require more information on growing with Envirolites, lighting, PAR, light spectrums for plants etc please visit our website www.tradehydro.com or call us for further details. A New Generation of Envirolites Self Ballasting Lamps – simple to install & wire • 100% PAR in the correct spectrum for growing • Generating much less heat than HID Lamps • Will not burn your plants or fingers! • Energy saving lamps – lower operating costs • High Lumen Output – directly above plants This new generation of low energy use, high efficiency, environmentally friendly horticultural lamps are designed for propagating, supplementary lighting and for growing plants, flowers, fruits and herbs all year round. Gardeners want to enjoy their gardening all through the year, with energy efficient Envirolites this is now possible ! Each lamp gives 100% PAR (Photosynthetically Active Radiation) light resulting in impressive plant growth. Plants need PAR energy and Envirolites are specifically designed horticultural lamps guaranteed to give maximum PAR energy and light in the correct spectrum. Envirolites give your plants full spectrum light between 400 and 700nw – which means great growth results in all propagation, vegetative or flowering stages and because they do not generate too much heat they can be used directly ( 5 to 6cms ) over plants using Envirolite Reflectors or hung in between plants to give supplementary lighting with our Lamp Hangers.
