BOTTOM HEAT 
ESSENTIAL 
GREENHOUSE CONDITIONS 
DUPLICATED 

NOW you too can start early 
cuttings, grow tropical bulbs and J 
plants with the skill of the pro- ¢ 
fessional. 
I am offering for the first time an inexpensive electric 
heating cable to be laid in the soil that will thermostatic- 
ally control whatever heat you need to start and maintain 
in the winter time such exotic bulbs as the Fancy Leaf 
Caladium, Gloxinia, Orchids—not to mention the early 
starting of seeds, cuttings, etc. 
To show you what difference a little bottom heat means, 
I planted three floats of dormant baby Callas and left them 
for two weeks without heat—at the end of this period not a 
root or bit of growth was indicated. In 48 hours with 
bottom heat of 70 degrees every bulb had set roots and 
top growth started. 
All one needs is a small glassed-in hot bed either in 
your yard or lath-house and follow directions furnished for 
the setting of the apparatus. It comes in two sizes, a 3-foot 
by 6-foot and 6-foot by 6-foot size.
