The widespread twist-in incandescent bulb produces light frequently in the longer wavelengths: far-red, red, orange, and yellow.

Advanced wattage bulbs produce a broader spectrum of light than lower-wattage bulbs. Incandescent can be used unaccompanied to marijuana seeds, but the marijuana plants will cultivate slowly and look sullen and yellow.

Incandescent combined with fluorescent work well, but fluorescent are an improved source of red light. Fluorescent tubes generate slightly less heat per watt.

With incandescent, heat is concentrated in the small bulb area, rather than the length of the tube, and can burn the plants.

In addition incandescent have less than one-third the efficiency of fluorescent bulbs in terms of electricity used.

If you make your mind up to use incandescent in combination with fluorescent, use two times the wattage of incandescent to blue source fluorescent. T

hat is, two 40-watt Daylight tubes to about three 60-watt incandescent, evenly spacing the red and blue sources.

The general floodlight has a spectrum similar to but somewhat broader than incandescent. Because they shed their light in one direction and operate at higher intensities. T

hese lights work better than incandescent, both as a single source and to supplement natural or fluorescent light.

The finest function for floodlights and incandescent is to complement natural and fluorescent light, in particular when the marijuana plants get bigger and during flowering.

Incandescent and floodlights require no special fixtures, although reflectors enhance the amount of light the marijuana plants accumulate.

These lights are effortless to hang or position around the sides of any light system, and their strong red band promotes more growth and good flower development as you grow hydro weed marijuana seeds.

Some of their energy is in the far-red band. Most purple gro-tubes and white fluorescent are deficient in this band, and addition of a few incandescent to make them more effective.

Several companies make screw-in spotlights specifically for marijuana plant growth.

Although they are an improvement over incandescent as a single source, these lights don’t perform nearly as well as fluorescent.

A 150-watt bulb would grow one plant perhaps four feet tall.

Two eight-foot fluorescent tubes (160 watts) will easily grow eight six-foot plants.

For supplemental lighting, the incandescent and floodlight work as well and are cheaper.
