"Artifical" lighting -- Any successes?
Those of us who earn our living as researchers don't really have a problem
with this. It's the way most professionals operate, especially those who "educate". Better to do it right than to be like the gardening show host who asked a guest what time of year was best to transplant your carrot seedlings out to the garden. ;-) "Dwayne" wrote ... Yes, you can. Mainly because she has some one else do the reasearch and work and she takes the credit for it. I have learned a lot. Dwayne "Repeating Decimal" wrote in message Dwayne wrote learned that from Martha Stewarts show before she got into trouble. I am surprised you can learn anything from that show. Bill |

"Artifical" lighting -- Any successes?
When I first got onto the internet, I was surprised at the invective aimed at Martha Stewart.... snip She still is allowed to make a living. Nevertheless, it is also the American way to poke fun when media idols are found to have feet of clay. Bill I'm glad I'm Canadian. We just assume that beforehand. ;-) |

You will have far better results with metal halide bulbs, or at least HO type flourescents. The regular tubes don't produce quite enough light, though some people make them work for them. There is a nice self-ballasted 75W reflector metal halide bulb on the market now that is inexpensive and easy to use. Excuse me if this is a dumb question, but does one need a special fixture to use metal halide bulbs? Or do they screw into a regular light socket? I'm very impatient to get some seeds started indoors, but I'm also trying not to break the budget. Thanks for any advice! Stella |

I'm very impatient to get some seeds started indoors, but I'm also trying not to break the budget. Thanks for any advice! Stella A self-ballasted light will screw into a standard incandescent socket -- but I've never seen a self-ballasted MH lamp. I have hight-pressure sodium lights, metal halide lights, and triphosphor fluorescents. The fluorescents are far cheaper and the plants do better with them. Look for a shop light or "troffer" style fixture for suspended ceilings that uses F32T8 lamps, with normal brightness or high brightness. The lamps you want are 4' long and look like normal fluorscents except they are one inch in diameter instead of 1.5". Look for something with a designation of "835" or "830" or "SPX30" (this indicates the color, or "warmness", and the color rendering, or "naturalness"). The lamps are usually less than $2 each at Home Depot or at a commercial lighting store. Forget the "one warm white and one cool white" conventional wisdom -- that worked 20 years ago before EPACT ruined 40W fluorescent lamps. These new triphosphor lamps are better anyway. Some of them (like Philip's or Sylvania's "Alto" series with the green endcaps) are low mercury. F32T8 lamps have an expected life of about 20000 hours, and an expected useful life of about 20000 hours. The old lamps had an expected life of 22000+ hours but you had to replace them at about 10000 hours or less because they lost too much brightness. If you already have 4' fluorescent grow lights, you can upgrade the ballasts to use the new lamps for less than $20 per fixture. Try to find an electronic ballast with a "ballast factor" (not to be confused with "power factor") of greater than 1. Best regards, Bob |

Pat Hi Pat, I generally agree with you, but I've found that when it's time to replace the lamps it is just about as cheap to replace the ballast with an electronic ballast and switch to inexpensive triphosphor F32T8 lamps. Cheap 4' shoplight lamps are usually only 25W or 34W now even though they say F40T12, and they don't put out nearly as much light as they used to. Best regards, Bob |

The problem is she was a director of the New York Stock Exchange who got caught with her hand in the cookie jar. It doesn't matter that she [allegedly] only stole one cookie. As a director of the exchange and as a former stock broker, she is held to a higher standard than most people. I don't really care about Martha, I'm waiting for Bernie Ebbers and Scott Sullivan [Worldcom] to get thrown in jail for 50 or 60 years. Best regards, Bob |

I am not saying she should not be prosecuted for any crimes she did--- if indeed she did. But I just find it ironic that the main focus in this huge nest of corporate rip-off artists turned to Stewart while the Enron crew and the rest of the "good 'ol boys" are apparently getting off scott free. |

One explanation I have seen several times is that it's still a "man's world", and the guys love to see a powerful woman brought low. Of course she could have handled it better, but then so could some of the major male corporate crooks. (FOB = Friends of Bush). -- Polar |
