Growing Kale in Cool Temps

November 7, 2018

Cool-season vegetables such as kale, lettuce, and spinach, and flowering plants such as cyclamen and snapdragons, grow best at temperatures between 50°F and 70°F (10–21°C).If you have a dedicated grow room or basement, you can install separate temperature controls for your space for warm & cool season crops, but you will still need some venting capabilities.

Kales thrive in cool temperatures.

If you’re growing plants in a tighter enclosed space, such as a small closet or a sealed grow tent, pay close attention to the heat output of your lamp.
