Tips for Growing Cannabis Indoors in Winter
When growing indoors during cold-weather months, lights-off grow-room temps drop several degrees, mimicking natural conditions that are favorable to plant morphology and bud quality when growing indica and Kush strains. Cooler lights-off, or nighttime, temperatures promote bud development and resin production, while limiting the stretch in plant height that occurs in the first two to three weeks of bloom phase. Night temperatures are optimum when they're three to five degrees less than lights-on temps. This day/night differential is most helpful when you're growing Kush strains whose genetic lineage comes from the mountainous regions of Central Asia. Cooler night temperatures in a sealed indoor grow room often result in high relative humidity. In grow phase and in pre-flowering bloom phase, a humidity range of 55 to 75 percent is acceptable. However, in peak and late bloom phase, when thick indica or Kush buds are present, relative humidity above 54 percent creates condit...
