HID Lighting lets you outsmart nature!

 
Do you live in a cloudy area? In a rainy area? Is it winter now, where your daylight (sunshine) hours are really low?

Well, no Problem...

With HID Lighting (grow lights), you'll have as much artificial sunshine as you need to make your plants thrive!

Let there be light!

High Intensity Lighting Bulb Everyone knows what a florescent light is... most of us know those were once the most popular grow lights. Florescent tubes are great for seedlings and "low-light" plants, but mature plants and flowers that are 6 inches or more in height need stronger light to penetrate through the length of the entire plant. They need HID Lighting.

A pair of fluorescent tubes put out around 1900 lumens of light energy. This only gives you about a foot of effective light penetration. A single HID growlight bulb can emit over 120,000 lumens! That gives you enough light penetration to grow your plants over 6 feet tall. And since you can keep your light so far above your indoor garden, a single light can cover a really big group of plants and flowers!

Our HID growlight systems can be hung from a simple ceiling hook and plugged in as easily as a home table lamp. It uses the plain-Jane electric plugs (120 volts) that you've already got. If you can hang a plant, you can hang a high intensity grow light!
