Lights & Tom, L I N K t o List

Square Foot Gardening List - http://www.flinet.com/~gallus/sqft.html

>How interesting. We just happened to have a light meter down in the basement

*I intend to post instructions on how yo use a 35mm manual camera to see
actual light levels.  But a $5 light meter is available in many places where
moisture and pH meters are sold.

>and I went to see what my fluorescents were putting out, in the centers it
was up to 1400 fc, at the ends down to 400 fc.

*Go to where I show, and you can see just how much and where the light quanity
is for these.

>My bulbs are mostly 2 or 3years old, though I replaced 3 of the 8

*These should be done as pairs, or wahtever that one ballast runs.

*At 2 yrs, that's 15% a year. 10% is norm, so those are likely 2.5-3 year
bulbs.  Write on them month/yr when you install them.  Where it's seen, when
installed.  Black permanent pen, like laundry, etc.

*They are 90% efficient where an incandescent is 25% about.  You are at about
65%.  Replace them.  hard on ballast and waste electricity.  Plants get less
benefit.  Estimate the date, write on bulb.  Use for temp use in a laundry
room if you must keep them.

>I also can't believe the engineer in the family didn't realize
the gardener in the family would appreciate this tool.
Tom

*Yeah... engineers are such jerks , huh.  Always with blindres on.
Can only see straight ahead, and only with that right hat on and
matching coffee cup and pencil protector.
(Still get yer old slip-stick?) <slide rule, y'all! sheesh! LOL>

Group Description: 

A Near OFF TOPIC Garden List, for however long a thread lasts.  A long-term,
temporary use group... Almost a Chat Room.  Garden Related, yet, not Strictly
Garden per se... If Timers, Spreadsheets, Databases, N,P,K.pH test kits, Green
Houses, Solar, Seedling Fans, Tech Stuff, & Shovels etc. are "Compost,"  &
called 'OT', Use This List! Disagreements welcomed, politeness absolute!
(Lotsa Links to be available, <I hope>.) You may hang around, or Sub and UnSub
whenever you need or feel.  Perhaps read messages on-web to avoid email. 
(This is how you 'vacation mode' gere.)  However YOU want to work it to meet
with your fellows for a little while, and hash over something that's almost
garden related.
