Temperature & Humidity Control

Most plants will tolerate normal temperature & humidity fluctuations. In general, plants grow best between 22 degrees and 27 degrees Celsius during the day and between 14 degrees to 20 degrees Celsius at night. Here are some points on why keeping a good environment is key to successful indoor gardening.

  • Lower night time temperatures help the plant: recover from moisture loss, intensify flower colour & flavour and promote healthy growing plants.
  • Excessively low or high temperatures may cause: plant stress, inhibit growth, or promote a spindly appearance and foliage damage or drop.
  • Cool night time temperatures are actually more desirable for plant growth than high temperatures. A good rule of thumb is to keep night time temperatures 10 to 15 degrees lower than daytime temperatures.
  • growing plants with the wrong type of humidity for the species can lead to all sorts of issues. One of the most common problems with adverse humidity conditions is misdiagnosis for nutrient deficiency!

  • But don't fear because we @ Norfolk Lights have you covered with the latest and greatest in monitoring & control equipment to keep your environment in tip top condition !
