At first the temperature will rise very high, but after one or two days it will drop. When the temperature reaches 850 it is well to begin to plant the seed. The temperature referred to is that of the soil, not that of the air, the latter being regulated by raising or lowering the sash. The position of the sash will, of course, have some influence on the soil temperature. management of the hotbed All small seeds, such as radish, lettuce, cabbage, tomato, cauliflower, kaj^tt^nu^. Fig. 21.—Commercial semi-hotbeds filled with a good crop of cucumbers aster, pansy, and the like, should be planted in rows, with 3 inches between rows and \ to \ inch between seeds, and at an average depth of \ inch. Lines, or furrows, are made by pressing the edge of a board into the soil. The seed is sown in these lines, or trenches, and covered with soil, the whole being pressed firm with a flat board and water sprayed on through a fine nozzle. Close attention should be given to the watering, which should be done early every sunny morning. Still closer attention should be given at all times to ventilation by raising or lowering the sash. Not only does this ventilation permit necessary fresh air to come in and discarded air to pass out, but it has a great influence on the temperature. When one understands that there are certain tem- peratures which are agreeable to each of the many plants, the reason for adequate ventilation and maintenance of the proper temperature is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appear
