Growth rate

Temperature plays a vital role in microgreens’ growth and development. One crucial aspect of microgreens temperature requirements is the impact of temperatures below 15C (59F) on their growth rate. When temperatures drop below this threshold, microgreens experience a significant slowdown in their growth, affecting their overall yield and quality.

  • Reduced Metabolic Activity: Temperatures below 15C (59F) hinder the metabolic processes essential for microgreens’ growth. Enzymes responsible for photosynthesis, nutrient uptake, and cell division become less active, leading to a slower rate of development.
  • Impaired Seed Germination: Low temperatures can delay or even prevent microgreens’ seeds from germinating. The enzymatic reactions necessary for seed germination are temperature-dependent, and when temperatures fall below the optimal range, the germination process is compromised.
  • Extended Growth Cycle: The slowed growth rate under low temperatures extends the microgreens’ growth cycle. This can impact production schedules and increase the risk of contamination or disease during the extended cultivation period.
  • Reduced Nutritional Value: Prolonged growth cycles due to low temperatures can affect microgreens’ nutritional content. The optimal accumulation of vitamins, minerals, and antioxidants occurs within a specific temperature range, and when temperatures deviate from this range, the nutritional value may be compromised.

Understanding the relationship between growth rate and temperatures below 15C (59F) is essential for successful microgreens cultivation. Maintaining optimal temperatures ensures efficient growth, high yields, and optimal nutritional content. Growers can implement measures such as heating mats or controlled indoor environments to regulate temperatures and mitigate the negative effects of low temperatures on microgreens’ growth rate.

Plant quality

Microgreens temperature requirements play a crucial role in determining plant quality, particularly avoiding leggy and weak growth above 25C (77F). As temperature rises beyond this threshold, microgreens experience physiological changes that compromise their structural integrity and overall health.

High temperatures accelerate plant growth, leading to rapid stem elongation and reduced leaf development. This results in leggy microgreens with weaker stems, making them more susceptible to lodging and breakage. The excessive heat disrupts the balance between cell division and cell expansion, leading to elongated and spindly stems.

Furthermore, elevated temperatures can hinder chlorophyll production, affecting photosynthesis and overall plant vigor. Microgreens grown above 25C (77F) may exhibit pale or yellowing leaves due to reduced chlorophyll synthesis. This impairs their ability to produce energy and nutrients, resulting in weak and underdeveloped plants.

Understanding the connection between plant quality and microgreens temperature requirements is essential for successful cultivation. Growers must maintain optimal temperatures to ensure sturdy and healthy microgreens. This involves implementing proper temperature control measures, such as providing shade during hot periods or using cooling systems in indoor growing environments.
