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

Unlike HPS, you can bring the light practically right on top of the leaves without experiencing leaf burn Its amazing how if its done right, you can have cuttings rooting in the middle of winter

The idea is a bit tempting: 150W HPS for less than $40, NPF ballast and bulb included, or even a 400W HPS for a little over $100, with a quad-tap CWA ballast and bulb Michael David Posts: 1495 Joined: Fri Jan 13, 2006 6:42 pm Location info: 30 Location: Middle Tennessee (Murfreesboro) USDA Zone 6b 7a Record low Jan 1966 -14*F Frost free April

The MH HPS bulbs also can and do explode sometimes during operation sending very hot glass not to mention the vapourized mercuric oxide (s) into the surrounding air Yes, if you are thinking HPS doesn't have mercury or have a UV hazard think again The inner arc channel contains mercury to helps the sodium burn arc at a higher pressure

In this class are HPS, or high pressure sodiums, and metal halides Besides needing a fixture, you will need a reflector, and a ballast to start off The cheapest of these are the standard floros If that is what you have, switch to at least the 40w bulb, and look for aluminum tape

Bamboos with larger leaves will probably do better under with limited light 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
