Greenhouse Heating. 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse beating that 

 are not understood. But please do not 

 ask The Eeview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



BETTES ADD ANOTHER FLOW. 



I am building a greenhouse, 21x125 

 feet. The side walls will be boarded, 

 without glass, and will be six feet high. 

 The side beds will be solid. There will 

 be two benches in the center, each 

 five feet wide, and there will be three 

 walks, each twenty inches wide. I 

 have been thinking of heating the 

 house by running two 2^-inch flow 

 pipes, one on each purlin, with three 

 2-inch returns on each wall and one 

 2-inch return under each bench. I want 

 to grow tomatoes and bedding plants. 

 We seldom get more than 17 to 20 de- 

 grees of frost here, near the coast of 

 British Columbia. The boiler will be 

 at one end of the greenhouse. A. O. 



The radiation described would be 

 sufScient for ordinary bedding plants, 

 but for the best results with tomatoes 

 a slight increase in the amount would 

 be found desirable, with the outside 

 temperature 10 to 15 degrees above 

 zero. The addition of one 2-inch re- 

 turn pipe would bring the amount of 

 radiating surface in the house up to 

 about 900 square feet, which is rather 

 more than can be handled to advan- 

 tage by two 2 1^ -inch flow pipes. Hence, 

 instead of putting in another return 

 pipe, it would be advisable to run a 

 2^-inch flow pipe just under the ridge

It has made thousande of dollars for many florists 

 and may do as much for yen. Your plants must have 

 certain, steady temperature to do their best. Use this 

 thermometer and you will know whether tbey are (ret- 

 ting what tbey need. It leaves a written record under- 

 lock and key.
