Temperature Management for Hydroponic Flowers
Core introduction to the main content: knowledge about hydroponic flowers, temperature management for hydroponic flowers, next, the site editor will introduce to the netizens.
The growth and development of plants occurs within a certain temperature range, and the growth and development of hydroponic flowers is also closely related to the temperature.
1. The three base temperatures for plant growth
The so-called three base temperatures refer to the lowest, optimal, and highest temperatures. At the optimal temperature, plant growth is most vigorous; below the lowest and above the highest temperatures, plant growth will be harmed to varying degrees, such as burnt leaf edges, yellowing and wilting leaves, leaf drop, growth cessation, or even death. Different plants have different three base temperatures due to their different places of origin.
(1) Lowest temperature plants native to tropical regions have a higher minimum temperature, generally starting to grow around 18 degrees Celsius; plants native to temperate regions have a lower minimum temperature, generally starting to grow around 10℃; plants native to subtropical regions have a minimum temperature between the two, generally starting to grow at around 15 to 16 degrees Celsius.
(2) Optimal temperature is generally around 25 degrees Celsius.
(3) Highest temperature generally, 50 degrees Celsius is the highest temperature for most plants native to tropical regions, but some species can tolerate high temperatures of 50 to 60 degrees Celsius.
2. Overwintering temperature for plants
Indoor hydroponic plants often choose tropical and subtropical ornamental leaf and flower species, so the lowest and highest temperatures, especially the lowest temperature, are closely related to the maintenance of hydroponic plants. When autumn arrives and temperatures gradually decrease, preparations for keeping warm and overwintering should be made.
(1) Good cold resistance varieties that can safely overwinter at around 0℃, such as aloe, chlorophytum, and kaffir lily.
(2) Some cold resistance, slightly protected can overwinter most of these plants are native to subtropical regions, such as clivia, geranium, stonecrop, aloe, hanging onion, purple velvet, silver leaf chrysanthemum, wandering Jew, and Commelina.
(3) Poor cold resistance these plants are mostly native to tropical regions, requiring a higher temperature throughout the year, with indoor winter temperatures not lower than 10 degrees Celsius; some cannot tolerate low temperatures below 5 degrees Celsius; otherwise, it is difficult to overwinter. Such as lucky bamboo, red gem Philodendron, green gem Philodendron, arrowhead Philodendron, split-leaf Philodendron, and虎尾兰 (hedgehog lily).
Based on the temperature required for hydroponic plants to overwinter, measures to prevent cold should be taken as soon as possible.
The above sharing is a specific introduction to the temperature management of hydroponic flowers, hoping to bring some flower knowledge to flower enthusiasts.
