Plant growth is closely related to temperature. Marijuana varieties are, in general adapted to warm if not hot climates.
Different varieties will reach their maximum rate of photosynthesis at different temperatures.
For almost all marijuana varieties, the rate of photosynthesis will increase sharply with increases in temperatures up to about 70F. Some strains reach their peak rate of growth at about 75F. Others, especially from areas near the equator, such as Colombia, may not reach their peak rate until the temperature is about 90F.
However, for all varieties, increases in the growth rate will be slight with increased temperatures over 75F. The average temperature for maximum is about 75 to 80F. In other words, normal household temperatures are fine for growing marijuana and no special temperature control is necessary for most gardens.
Hope that helps bro!
