Even in legal states, you may want to conceal your crop from judgmental neighbors and definitely from potential thieves. Growing indoors allows you to grow discreetly behind a locked door.
Without proper airflow, a grow space can experience rapid changes in humidity or develop pockets of CO2 depletion, neither of which are good for plant growth. CO2 depletion can lead to nutrient lockout, and areas of high humidity are prone to pest infestation, mold, or mildew.
Because the amount of light a plant receives is so important, you’ll need to make your indoor grow space light-tight. Light leaks during dark periods will confuse your plants and can cause them to produce male flowers or revert to a different stage.
Lighting, of course, will also play a role here. If you’re already using a lighting setup that gives off a lot of heat, you’re at an advantage because these will already give your plants adequate heat to stay warm enough during the day. But at night, a significant reduction in temperatures overnight may be dangerous particularly after your lights are switched off. To resolve this, just switch your cycles around: see what happens if you leave your lights on overnight to make up for the cooler temperatures, then turn them off at daytime when the temperatures are more consistent and appropriate.
With winter here, many of you who may be growing cannabis at home might be wondering how to help your plants thrive during the colder months. The truth is that, no matter what the weather is like outside, you still have to pay attention to the right growing conditions for cannabis.
If you don’t have one already, this winter is a good time to invest in a thermostat so that you can always keep a close watch on the temperature especially this time of year when it’s prone to rapid and quick changes.
Additionally, you should be keeping a close eye on the difference between daytime and nighttime temperatures especially during the first 3 weeks of the flowering phase. If the change in temperature when you go from day to night is far too big, this may result in stretched-out cannabis plants with wide spaces among its internodes. For optimum growing results in the first 3 weeks of flowering, the temperature differences from day to night should be around 3.6-7.2F. For the rest of the growing period, you should be looking at a discrepancy of around 18F when going from night to day.
During winter, closely monitoring your grow is critical to ensuring your plants withstand the cold temperatures. Small things can dampen your efforts, such as leaving a small window open which allows bitter, cold air to come in; having your heating systems break down at night; the presence of mold, and much more.
