iGROW lights change the economics of growing under roof, making it far more economical. Now, anyone can afford to become a grower; to feed their family or make farming their livelihood.
After three years of testing and research, in collaboration with the USDA, some of America’s finest university based agricultural lighting scientists, and with a number of the premier indoor growers in the country, iGROW is here.
iGROW is the first and only induction light developed for the sole purpose of growing plants. Up to now, no one has taken a serious look at this application, nor was there any data in existence to support this idea. No university studies, no scientific research, no commercial crop or floriculture growers using induction lights in their greenhouses. More...

High Intensity Discharge (H.I.D.) Grow Lights

Metal halide lights were created to provide a spectrum as close as possible to that of the natural sunlight. This coupled with their intensity and energy efficiency, makes them ideal for indoor gardening. The bulbs range in size from 100 watt to 1000 watt with 400 watt and 1000 watt most popular.
An abundance of blue light emitted by metal halide makes them the best light for propagation and vegetative growth, promoting short internodal length. High Pressure Sodium lights do not emit as broad a spectrum as Metal Halides lights, but have many advantages, especially when used in conjunction with halide. Sodiums last longer, and burn brighter, but are still more energy efficient.
More yellow/red colour in the spectrum and less blue promotes a higher flower-to-leaf ratio in flowering plants. H.P.S. lights are widely used in commercial greenhouses, where natural sunlight provides sufficient blue. A combination of the two lights provides the best balanced for indoor grow room, especially when used with a light mover. 430 Watt Son Agro H.P.S. bulbs which supply 30 extra watts than regular ones are now available. This extra light in the blue end of the spectrum is great news for indoor growers. If you are planning a "single lamp" grow room, you can still get the benefits of both halide and sodium light.

High pressure sodium and metal halide "conversion bulbs", specially made to operate with M.H. ballasts, and is available in 400 watt and 1000 watt models. The bulbs can easily be interchanged as needed, using the same ballast and fixture. The size of the light needed will depend on the size of the growing area and the type of plants you wish to grow.

All In One Lighting Kits

Now available online is the Sun System HPS 150watt lamp. Reflector, ballast and bulb all included. Has 16,000 lumens, and provides all the output and colour spectrum needed for successful indoor gardening. Perfect for the first time gardener to get everything they need to the experienced green thumb who wants to efficiently light their grow room or greenhouse.

LED’s are efficient have a long life and are versatile. They also produce little heat which allows them to be placed quite closely to plants.
The price of LED's is often offset with the amount saved in energy consumption over the life span of your LED light. Research is still being done to find an LED equivalent performance to an HID 1000 watt bulb for an affordable price. From our research the best results we have seen have been from Sunshine Systems used for supplemental lighting over seedlings and cuttings. The Growpanel 45 we carry only uses 45 watts and is a great solution comparable to a 250 watt HPS lamp. They also feature the Grow Panel Pro which uses only 300 watts but is comparable to a 1500 watt HID.

Light Movers    
The most efficient way to use high intensity lights is to have them moving within the grow room.
There are many advantages to this, and a number of different ways it can be done. Moving the lights will eliminate plants tendency to grow toward the light source and provide light to areas which otherwise may be shaded. Since the light is moving, it can pass quite close to the plants without burning the leaves.
Moving lights cover more area than stationary ones, reducing electricity costs and ensuring more even growth. More intensity also allows plants to be placed muchcloser together, greatly increasing yield and quality. The size and shape of your room will determine the type of light mover that will best suite your needs.
Lineal movers carry the light fixture slowly along a track and back again during the light cycle. Most are six feet long, support a single lamp, and are recommended when the growing area is long and narrow.
Circular movers are best when the length and width of the room are similar. They are designed to carry one, two, or three lights, in a 360 degree circle, ideally lighting a ten by ten foot area. This diameter can be reduced but rarely extended.
Two arm and three arm movers are most popular, with the latter supplying much more light per square foot. More intensity means plants can be placed much closer together, greatly increasing yields.
Advantages of using light movers:

• more even growth over a larger area
• lamps may be placed closer to crop
• increase growth by 40%
• stronger plant stems
• counteract leaf shading
• circular movers can move up to 3 lamps
• 1 or 2 meter linear track support single lamps, extension kits are used for additional lamps
