How to Grow Cannabis in Cold Climates
Growing cannabis in regions with cold climates (such as in northern European countries like Germany or England) presents some characteristic challenges.
It is important to note that the optimal temperature range for cannabis cultivation is 20 – 22ºC minimum (night) and 24 – 26ºC maximum (day). However, cannabis can be grown within a range of 18ºC minimum at night and 30ºC during the day.
Outside of these limits, the plant will have more difficulty carrying out its biological processes, which can lead to:
Difficulty absorbing nutrients. Delayed or stunted growth. Poor root structure. Hermaphroditism (this can occur due to thermal stress, especially when temperatures are too high). Root rot. Increased chances of mold and fungal attacks.
