Most seeds sprout between 23.9 and 29.4 degrees Celsius (75 and 85 degrees Fahrenheit), and some seeds require a long period of cold temperatures before they can sprout. The influence of temperature mode on particular parts of a plant . Growth Temperature.

This source of cool air is critical. Soil temperature has a great effect on plant growth by influencing water and nutrient uptake Toselli et al., 44 root and shoots growth Weih et al. So whether it’s extreme heat or cold, temperature does affect plants and their growth. Aspect. Temperatures affects plant growth and distribution. Soil temperature has a great effect on plant growth by influencing water and nutrient uptake Toselli et al., 44 root and shoots growth Weih et al. Cold damage also shows up in early spring when a warm period encouraged new growth, which is particularly susceptible to a sudden freeze. These three environments have different causes and effects, each requiring unique responses to avoid injury. High soil temperature is more crucial as damage to the roots is severe resulting in substantial reduction in shoot growth. This is true high or low. Marijuana plants are impressively robust, but of course it is still a good idea to keep the environment within the ideal temperature range whenever possible. This is usually directly under the center of your grow light, at the tops of your plants. 45 Water uptake This is due to the increased viscosity and decreased absorption rate of water at low temperature Toselli et al. Check plant growth A-F every morning at 6:45 a.m. or around there. The effects of temperature on the rate and extent of root colonization are complex, the responses varying with both fungus and plant (Smith and Read, 2008). And cold-resistant plants successfully grow even at temperatures below 0°C. At lower temperatures, plants reduce their use of carbohydrates as energy and increase their storage as sugars. High air temperature reduces the growth of shoots and in turn reduces root growth. When plants sprout record data. 44 Decreased water uptake reduces the rate of photosynthesis. Some plant seeds, including cool season vegetables, like lettuce and broccoli, germinate best in temperatures between 55 and 70 F. (13 to 21 C.), while warm season plants, such as squash and marigolds, germinate best when temperatures are between 70 and 85 F. (21 to 13 C.). 44 Decreased water uptake reduces the rate of photosynthesis. Use the link below and it will lead you to a post that helps you understand this. Before watering, allow cold water to warm to room temperature; also, water additives that are harmful to plants will settle in warmer water. 17. Does Tab water affect the growth of a plant?

Veihmeyer and A. H. Hendrickson Annual Review of Plant Physiology Photosynthetic Response and Adaptation to Temperature in Higher Plants If the soil gets too hot or too cold then the uptake of water and the growth of roots will slow up.
