My GH is a bit too far from the house for the Radio Shack units to reach, so
I bought an Oregon Scientific unit - temperature (with alarms and max-min)
and RH from 300 feet, AND it has a radio controlled clock that is updated by
the atomic clock broadcasts.

These items are available at a lot of different places. Carter & Holmes
(online) has min/max thermometers ($27), but so does Home Depot, which
is where I got mine. Most online orchid supply places have hygrometers,
but my experience has been that they vary in accuracy. My most accurate
hygrometer is a cheap one that I got at a local nursery. BTW,
Charley's Greenhouse is a good Internet source for orchid tools.



Charley's Greenhouse is a great place to overpay for things....by a
huge margin.

I have been using a max/min digital hygrometer/thermometer that I got
from Farmtek for $22. It seems to be pretty accurate when compared to
my 'olde tyme' cheap dial hygrometer....it drifts a little at the low
range, but if my greenhouse is at 20% humidity, do I care if my
hygrometer says it's 10%???

The Farmtek item # is 102447 (the new catalog arrived today).

And don't forget about the temp/humidity gauges that report from the GH
to your house via radio. I have one by the bedside and couldn't live
without it. Especially in the cold rain when the GH heater goes out and
I get to run outside in my pajamas to re-light the heater.

I got the Farmtek catalog too. Looks interesting, good prices and stuff
(like thermostats)

Don't forget about Grainger's.com either, for cheap thermostats. and
other supplies. The heater froze solid one year than they had the
replacement parts.

Oops the radio gauge is from radio Shack.
