HOTKAPS are CHEAP CROP INSURANCE FOR YOU 
Here s Positive Proof that Hotkaps Speed Growth, Produce Stronger Plants! 
This photo 
conclusively 
proves how 
Hotkaps 
speed 
growth, and 
produce 
hardier 
plants. The 
row of squash 
on the left 
did not have 
Hotkap pro¬ 
tection. The 
row on the 
have Hotkap protection. All other growing conditions 1 were 
exactly the same. Make this test yourself. Know that all we 
claim for Hotkaps is absolutely true. Use them for bigger 
earlier, more profitable crops! 6& ’ 
This photo shows how Hotkaps are used by the 
small gardener for the protection of either vege¬ 
tables or flowers. The low cost of Hotkaps, their 
ease of use and their remarkable results make 
them invaluable for any type of grower. 
This actual 
photo shows 
the develop¬ 
ment of to¬ 
mato plants 
with and 
without 
Hotkap pro¬ 
tection. Note 
the weak, 
undersized 
plants (indi¬ 
cated by the 
arrow) which 
did not have 
Hotkap pro¬ 
tection. 
Then note the larger, sturdier plants which did have Hotkap 
protection. Notice, also, the perfect mulch maintained by the 
Hotkap, while the exposed soil is badly crusted.

late frosts and storms offer no dangers to the wise 
growler who uses this inexpensive method of crop pro¬ 
tection.

safe even as far north as Minnesota when crops 
are protected from frost, wind, and rain by these 
“Individual Hothouses."
