As far as I know, HPS (high pressure sodium) is the most efficient lighting system With grasses, etiolation doesn't seem to be as much of a problem as it would with e g tomatoes

The Excelvan PG01 LED grow light will emit light in the red and blue wavelengths at 620-630nm and 460 to 470nm, these wavelengths correspond to chlorophyll's absorption peaks and will greatly enhance the photosynthesis of your plants This LED plant light uses just 14 Watts of power and generates very little heat so unlike regular light bulbs, HID lamps or fluorescent tubes which means you can
- Dos and Donts - bambooweb. info
A 250 watt hps should be adequate for small seedlings in a 80x80cm area, as long as you have lots of reflectors keeping the light in Once your seedlings get bigger, they will start to require more space, and a light that is set more like 3-5 feet away from the seedlings to get adequate coverage

A 600W HPS - the proverbial design "sweet spot" - coupled with a digital ballast - less than $250 USD, with a power factor of 0 99 or so - would be far less efficient due to heat generated by the bulb, but still quite respectable

MH has hazards, HPS is better, but it has a very high operation temperature, as is the MH as well also your power costs are VERY high You can get a PFC easily buy buying a motor run capacitor and placing it across the LV side of your ballast they are usually 250V rated at several to 10s of uF

One option may be to get a 1000watt HPS, or metal halide plant light, which should be enough to keep the plants happy, but cost a lot Another option is to keep the plants outside during the warmer months and bring them inside for winter

From seeing commercial growers, I usually see greenhouses have metal halides, hps, or T5 flourescent bulb setups so having the right kind of light is very important For example, a 6400k cfl bulb seem to do fine in causing vegetative growth, but it seemed to lack the ability to cause shooting budding in seedlings that I have grown in the past
