Vitamin Bi Grofast Cartridges 
MAKES PLANTS SHOOT UP 
$1.00 a box, postpaid. 
According to Better Homes and Gardens for October, 1939, the use of vitamin Bi 
has produced Daffodils 42 in. tall with blossoms large enough to hide a salad plate; 
Roses with 5 in. buds; improved the quality and quantity of citrus fruit; doubled the 
size of orchids; produced Hyacinths with flower heads a foot long; transplanted 
Roses in bloom without loss of a bud; saved trees from destruction by root rot; 
induced vigorous growth in weak and sickly plants, and produced luxurious root 
growth on cuttings and seedlings. 
Now, we offer the new GROFAST CARTRIDGE which supplies vitamin B x in 
a form easy to use. It produces the same results as obtained when B x is applied by 
the back-breaking sprinkling can method. 
EASY TO APPLY—Merely remove the nozzle from your hose, drop into it a 
GROFAST CARTRIDGE, replace the nozzle, turn on the water and distribute vitamin 
Bj to any desired part of your garden. Sprinkle just enough to moisten well the soil 
surface. Then water the ground thoroughly to wash the vitamin into the soil and 
bring it into contact with the roots of the plants. 
INEXPENSIVE METHOD.—The cost of Grofast Cartridges is very small — only 
$1.00 for a box of 30 Cartridges which are sufficient to “vitamize” an average garden 
once a week for an entire growing season. 
SPECIAL OFFER 
If you send us an order for plants from this catalogue amounting to a dollar or 
more, not including collections, we will include a box of Grofast Cartridges at just 
one-half price, or 50c.
