| To monitor the temperature of your greenhouse, set up a thermometer inside, in the shade, and a the level of your plants (a minimum-maximum thermometer is preferred). The usually excepted optimum temperature for most plants is 80' F. At higher temperatures your plant's growth will decrease and the may die if they get too hot, too long. Use your thermometer to record the daily extremes of temperature, and try by careful ventilation and heating adjustments, to even out the differences as much as possible. |
