what temperature lightbulb should I buy?

I thought you'd never ask.

Years ago, when I was writing for a retail magazine, I did an article about lighting. I learned a bundle. Most important: Ignore the advertising, the pictures on the packages, even the store displays, and pay zero attention to that name on the package "Daylight Fluorescent". It's baloney. Anyone selling anything -- GE are you reading this? -- can push their lightbulbs as "daylight". There is no law against it. It's a free country. Probably the Constitution says GE and others can do that.

What you can look at instead is a number on the package that says: CRI. Most of the time it will be on the fluorescent package near the stuff about watts and color temperature.

CRI - stands for "Color Rendering Index". Wikipedia will tell you all about it: http://en.wikipedia.org/wiki/Color_rendering_index

Back then, Phillips was the leading quality manufacturer of top rated tubes, with a CRI of 98. It was hard to find them, but they were great. I used them at home and loved the light they produced. It's like being outdoors in the middle of the day. Blues were blue, reds were vivid red, they were easy to ready by, and plants loved to grow under them.

Today, I only see one high CRI Phillips bulb:

I don't know where you buy these and I don't know if you can find others.

But when you go out to shop for these, look at one thing and one thing only: The Color Rendering Index. Because THAT is ALL that matters.

And I have wanted to tell someone that for 30 years.

(If you were a retailer, I would repeat one of my story lines: The best lighting is the one that sells your products.)

ought to I propose which you purely look into sprouting first. This demands no precise kit or particular lighting fixtures furniture. Then, while you're taking section on your harvest of a sort of seed sprouts, which you will check out into what style of vegetables improve in low easy. Then which you will have the potential to augment into the improve easy section. additionally which you would be sure into small (micro) greenhouses. which you additionally can build a small improve room ideal out from a number of your homestead windows. i comprehend of one fellow who makes use of a decision of mirrors that direct gentle from the exterior to a small indoor backyard. whats up, the possibilities are high endless. experience your self.
