Horticultural Lighting Information

Horticultural Grow Lights for indoor and greenhouse production



Coverage: a 400w system is effective up to a 5 x 5 area, but think 4 x 4 for high energy plants.

A 600w system bumps up to 6 x 6.

And a 1,000 system covers up to a 10 x 10, although the edges of that area will be short-changed. It's better to think 9 x 9.

Light movers help greatly. We will be stocking them shortly.

Metal Halide systems produce predominately blue light for heavy vegetative growth.

High Pressure Sodium systems produce more orange/red light for flowering plants. You can mix and match the two for balanced light.

For lettuce, spinach, herbs, and chinese vegetables you have the choice of High-Output Fluorescent lighting, which is cheaper energy-wise, or 400 and 600 watt HID lighting, which is more expensive to run but puts out more lumens. For the big guys like tomatoes, squash, cucumbers, eggplant, and melons we only recommend High Intensity Discharge (HID) light systems.....400, 600, and 1,000 watters. Artificial lighting, even 1,000 watt HID, is weak compared to natural sunlight. That's why you really have to hit them with nearly all the lumens your electric bill can stand!

Galaxy Electronic ballasts are relatively new. They are more expensive up front, but have their advantages:

-can run either MH or HPS bulbs so you get two ballasts in one.

-can run on multiple voltages.

-are lightweight and quiet.

After you have chosen your ballast, reflector, and bulb you will have everything for one (1) complete system...just hang it and plug it in. And remember, advice is free, so if you're not sure then give us a call. Our top priority is helping customers achieve results they can rave about!
