‘es importance of correctly controlled 
greenhouse humidity is now recognized 
as a very necessary factor for optimum 
plant growth. Daily we hear reports from 
commercial growers, our agricultural ex- 
periment stations and from hundreds of 
small, amateur growers and _ hobbyists 
throughout the country as to the value 
and many benefits derived from properly 
controlled humidity — especially in re- 
lation to orchids.

tion low-pressure H-261 nozzle tip, espe- 
cially designed to atomize water at 
low pressures, and special copper sweat Tee 
fitting designed for use with the H-261 nozzle tip. 
The all brass nozzle tip with a 4” 
thread screws directly into this special 
tee fitting. The 120 mesh Monel strainer, which 
will not rust or corrode, protrudes approximately ! 
into the body of the fitting to facilitate cleaning. 
We recommend a faucet at the far end of your 
supply line for this purpose. 
Nozzles available in 60°, 80° and 120° spray angles.

In developing our Low Pressure Green- 
house Humidity Systems, our chief con- 
siderations were maximum efficiency with 
the best materials at the lowest possible 
cost. This system can be manually operat- 
ed or combined with automatic controls 
to make up a simple, efficient, low-cost as- 
sembly. For installation we recommend 
4” copper tubing available at your 
plumbing supply house.
