The Florists' Review 



Junk 12, 1919. 



This bouse is piped with one 2-inch flow 

 and two 2-inch returns for each bench. 

 Is that sufficient piping? We wish to 

 disconnect this house from the rest of 

 the old houses and add it to the new 

 house. What size of Kroeschell boiler 

 will be required to heat the two houses 

 to a temperature for growing roses? The 

 outside temperature in this vicinity sel- 

 dom drops below zero; the average tem- 

 perature is 22 decrees for about forty 

 days. 



How many flows and returns should be 

 placed in the new house and what is the 

 best system of arranging the pipes? If 

 we run the pipes under the benches there 

 will be eighteen ia^xes of fall for the 

 flows and returns. In other words, there 

 will be eighteen inches of fall in 104 

 feet. B, F. C— Ida. 



The amount of piping and the size of 

 boiler required tor heating the two 

 houses described will depend upon the 

 number of nights in which the tempnra- 

 ture is likely to drop to zero during the 

 winter. If this happens only on two or 

 three nights, it will probably answer if 

 the piping is planned for 10 degrees 

 above zero, and then when it drops to 

 zero a little extra attention will suffice 

 to keep up the temperature in the houses. 

 Under these conditions the piping in the 

 house forty-one feet in width would be 

 sufficient, but two or three additional 

 returns will be needed if a zero night 

 temperature is of frequent occurrence 

 and only ordinary attention is given. 



For the house fifty feet in width we 

 would use a 2^-inch flow upon each 

 plate to supply a coil upon each wall. 

 In addition we would use three 2%-inch 

 overhead flows, placing one under the 

 ridge and the others about halfway down 

 the sashbars. Use each of these overhead 

 flow pipes to supply the coils under two 

 benches. Each of these coils should con- 

 sist of two 2-inch returns. There should 

 be three 2%-inch pipes in each of the 

 wall coils. 



The difference in the length of the 

 houses gives them practically the same 

 amount of exposed glass, and for 60 de- 

 grees about 1,700 square feet of radia- 

 tion will be required for each house. To 

 heat the two houses we would select a 

 hot water boiler rated for at least 4,000 

 square feet of radiation, especially if 

 soft coal is to be used. 



There is no occasion for allowing more 

 than one inch of fall for ten feet, and 

 one inch of fall in twenty feet will 

 answer if care is taken in grading the 

 pipes so that air pockets will be avoided. 

 It is advisable to keep the returns as 

 high as possible, unless considerably 

 above the top of the boiler.

The Market. 



Business is slow and does not nearly 

 take up the receipts, which are heavy 

 and have brought on a glut in the mar- 

 ket. Besides heavy cuts of indoor 

 stock, the outdoor cut is also heavy. 

 The demand from out of town holds up 

 fairly well, although it has let down 

 somewhat the last fortnight. 



The rose supply is heavy and includes 

 many fancy blooms. Oaraktkibs, too, 

 are in good supply, but a great many of >) 

 them are of rather poor quality. Some 

 Easter lilies are again available. Ru- 

 brums and callas may be had. The sweet 

 pea cut is limited. Gladioli are fairly 

 l)lentiful and, relatively speaking, meet
