The difference comes in the spectra of light emitted by the bulbs.
Incandescent lamps are totally ineffective as grow lights; they have very limited spectrum, are very inefficient in their use of electrical power to light output. They also put off far too much heat per watt to use in horticulture.

You can use standard fluorescent tubes for starting seedlings indoors, but to grow your plants farther they won’t get the wider spectrum of light they require. That is when you need tubes that are designed to promote plant growth.

Vegetables or foliage plants grow best in blue spectrum light, which is a cooler form of light. Metal Halide lights are the most popular form of blue spectrum lighting.
Flowering plants grow best in red-orange grow light. The best type of red-orange light is the high pressure sodium light (HPS).
Other bulbs HID, Mercury Vapor, and LED bulbs

sure, it fairly concerns. ordinary flourescent bar light fixtures do not comprise adequate gentle spectrum for plants to enhance to their skill. imagine that each wave of the gentle spectrum is a diet that the plant needs. Now the HPS and MH bulbs containg the biggest spectrum of sunshine and that is what makes them perfect. The MH gentle will mimic the spectrum of the summer season solar which in turn will reason the plant to stay in that is enhance cycle. once you want to "flower" your plant, you turn to the HPS bulb, which simulates the fall or "pink" solar. After reducing the gentle cycle back to twelve on 12 off. The plant will be compelled into that is flowering cycle. i might want to bypass to a hydroponics keep and %. up a HPS bulb and a MH blend bulb with a balast and also you're in employer-
