Factors to Create a Perfect Growing Environment

There are many factors to creating the perfect growing environment. The best climate to grow marijuana is dependent upon all of these factors combined. An error in just one of these aspects can affect your yield in major ways. Here are the most critical environmental factors for growing the best weed:



Light is one of the most critical factors when growing marijuana indoors. You want to provide just the right amount – not too much or too little. Different strains may require a bit more or less, but the average amount is the same.

If you don’t have enough light, your yield will be smaller. Different lights in the color spectrum can affect how your plants will grow, both vertically as well as how wide and full they get. Some LED lights provide the a fuller spectrum of light that will help to yield the healthiest and largest crops.

A generally accepted light schedule during the vegetative process is 18 hours on and 6 hours off. During floral triggering and growth, 12 hours on and 12 hours off is ideal. Please remember that this can vary slightly by marijuana strain types.


Temperature is another important aspect to consider when growing marijuana indoors. What’s the best climate to grow marijuana indoors? This will vary throughout each growing stage and even with your light cycles. It can vary a lot. But remember that it is an important aspect in achieving the best pot yield possible.

When the lights are on, it is ideal to keep your marijuana at temperatures between 70 and 80 degrees Fahrenheit. During lights off cycles, temperatures between 64 and 71 degrees Fahrenheit are ideal. A temperature between 73 and 76 degrees Fahrenheit seems to be a pretty agreed-upon standard amongst growers.

Air Circulation

Proper air circulation with plenty of fresh air from a gentle breeze will help your plants to grow fast and strong. But, more importantly, good airflow will help to prevent major problems with your crop like mold and pests. Some common pest that shows up when growing weed is spider mites and fungus gnats.

If possible, you will want a gentle breeze blowing both over and under your plants. You’ve got it perfect if you notice a slight rustle of the leaves on your plants. There are two key factors to remember. Do not have a fan blowing right at the plants. However, do not allow the leaves to be sitting still without flowing air moving around them.

One last thing to remember about air circulation is to vent out heat from your grow lights. Often times, these can create too much heat for the indoor climate. Simply fan out heat from the top of your grow operation.


Your crops will produce a better yield if you have light reflecting back upon them from the original light source. Use a reflective material along the walls and floor to get maximum light exposure to all areas of your plants.


Humidity is not a very critical factor when creating the best climate for growing weed indoors. However, remember that extreme levels of humidity can affect your pot yield. If you live somewhere with extremely humid or dry conditions, consider an air conditioner or humidifier to even things out.

40 to 65% humidity is ideal during the vegetative phase. The flowering stage requires slightly less humidity at about 40 to 60%. Too much humidity can allow for mold and other issues with your plants.

The Importance of Having the Best Growing Environment

One last thing to consider is cross-contamination with your pot plants. You want to make sure that you are handling your plants with clean hands and tools. Basically, you should be completely controlling the environment for your cannabis plants. Don’t allow anything in that you wouldn’t want to smoke, eat, or consume in any other way.

Final Thoughts

Now you know the most critical aspects of the best climate for growing weed. If you live somewhere that you are legally allowed or licensed to grow, you have the basic knowledge needed to do so. You should, of course, make sure that you are obeying all local laws and legislation. It’s also always the best idea to talk with your doctor about your marijuana use. Happy growing and good luck with your future yields!
