[net.garden] need info on grow lights

rew@cbosgd.UUCP (Bob Warren) (12/10/85)

Does anyone know a good source for grow lights?  What I am looking for
is a 3-4 foot flourescent light mounted in an adjustable-height stand.
The plants would be placed directly below the light and the light would be
adjusted as the plants grew.  Burpee used to carry something like this--
does anyone know of another source?

Thanks,

The "experts" say you should buy the cheapest light fixture you can find
and use one cold white tube and one warm white tube.  If you are growing
plants for flowers you might want to add some red tungsten lights.  The
so-called "gro-lites" give off less light and lumens is the name of the
game. By mixing the warm and cool white tubes you get a fairly flat
spectral response.

Many years ago (how's that for honesty) I bought my wife one made by
Sylvania.  It uses the 24" bulbs rather than the 48" ones so its good
for flowers on a counter top.  I got mine at the local Sylvania distributor
who also sells fixtures retail.  It wasn't cheap but she likes it and 
it still works fine.  First place to try then is a place specializing
in ceiling fixtures.  Next approach is to buy the growlamp packages
GE sells for about $14 in a style similiar to their "Brightstick".
This will require mounting on the underside of something so its good
for use in a cabinet or bookshelf arrangement. Last choice is what
someone else suggested, by cheap ($12) flourescent fixtures that take
the 48" bulb and buy bulbs in hardware or nursery store.  Definitely
the most light for the money but only suitable for basements (which
is where I keep my two all winter for fresh herbs and stuff).

There is nothing special about the light fixtures for grow lights.  Any
standard light fixture will do.  Your local yellow pages will list
stores specializing in light fixtures.  Also, visit a good hardware
store to study the bulbs available.

A plant's light needs can be met by a mixture of ordinary flourescent and
incandescent lighting.  I believe a ratio of 60:40 fluorescent to
incandescent is recommended.  Office fluorescent lighting with some
daylight mixed in works well too.  This is why some people say that
bringing their plants to the office rejuvenates them.  Especially since
many offices leave the fluorescents on 24 hours a day.

The problem is the intensity.  You probably do not want to leave room
lights on 12-16 hours a day just for a plant in the corner.  You can
buy both fluorescent and incandescent spot flood bulbs called grow
lights.  These use phosphor mixtures that give a compromise of light
frequencies.

Once you see what bulbs are available at your local hardware store, you
can buy a fixture you like at the lamp store.

A slightly embarrassing (to some) source for high-quality indoor plant
growing parapher...er, equipment (fluorescent and incandescent lamps,
fixtures, planters, timers, etc.) is your local headshop.  Also see
magazines which cater to such folk for mail-order sources of same.
[Discretion advised depending on where in the country you live.]

Yeah, it's weird but it's true.  (They're also about the only place to get
a decent balance at a decent price...)
