What mix of red and blue light is best for vegetative growth and for flowering?
We recommend all blue light for vegetative growth, or seven blue bulbs for every one red bulb. For flowering we recommend two red bulbs for every one blue bulb.

 

How many bulbs do I need?The maximum coverage of a bulb is 24" at 24" above the plant.
For medium light intensity plants, we recommend three bulbs to cover a 4' x 2' area, at 6"-12" above the plants.
For high light intensity plants, we recommend using the bulbs at 100% density at 1"-6" above the plants. I know we're in the business of selling bulbs, but it makes sense. After all, a food plant such as tomato or corn wants full sun. No indoor lighting is anywhere near as bright as the sun. Therefore 100% density cannot be "too bright". This means that you should use 30-50 bulbs to cover a 4'x4' area. This will be a similar coverage area to a 1000 Watt Metal Halide for less than half of the power. (LED light, however, does not currently penetrate as far as metal halide. We suggest that you grow plants or cuttings that are no taller than 24", or that you supplement with side lighting.)

 

What about fixtures? Our bulbs work in all standard fixtures that fit flood lights. We don't sell fixtures so that we can skip the whole liability issue. This is a good time to mention that you should always use a qualified electrician for any electrical work that you do. Also be sure and use a three wire (grounded) system that is connected to a surge protector and GFCI. That being said, it is possible to use standard track lighting and fixtures, such as those from USA Light and Electric. You will need the following (links are on the USA Light and Electric site):
