TO DELAY FLOWERING 

TO DELAY FLOWERING BY THE USE OF ARTIFICIAL LIGHT 
For this purpose select the better mid seasonand late varieties and grow as you nor- 
mally do, 
All varieties should be planted the same time as when no lights are used. 
Pinch all varieties late to avoid tendency for crown buds. 
Light with 40 watt lamps usingtin reflectors hung at intervals of five feet over the 
bench. 
Obtain light intensity between 3 and 10 foot candles. 5 foot candle intensities are 
economical and effective. Your local lighting expertwill explain these terms if you 
are not familiar with them. 
Start lights no later than August 10th. Starting after this date may cause malformed 
flowers and long necks. 
Turn lights on at dusk and continue lighting three hours every evening. 
Treat each night until youhave treated 3/4 asmany nights as you wish to delay flowering. 
In other words treat for twenty days if you wish a thirty day delay in flowering. 
Take the first bud showing after light treatment is stopped. 
Pinch Pompons the last time 90 days before light treatment is discontinued. 
Grow at a night temperature of not less than 50 degrees where possible, and con— 
sistant with local weather conditions. 
Be careful that the lights from the bench treated does not light a bench nearby that 
is not treated. This will cause part of the bench not under treatment to be delayed 
in flowering and consequently upset growing plans for bench not under treatment.
