Ideal temperature for growing cannabis

If you are growing marijuana in a grow room, keep in mind, the maximum temperature for marijuana grow tent success is 85 °F. Temperatures higher than this will result in the plant’s death.

During the flowering stage, however, the ideal temperature to grow marijuana plants can be a little colder. The temperature should be kept between 65-80 degrees Fahrenheit (18-26ºC). The second half of the flowering stage is when the temperature should be at its coolest. This helps your marijuana plants produce flowers with rich color, as well as increased trichomes, denser buds, and more potent smell.

When growing outdoors, the ideal temperature is a little cooler. Marijuana outdoor grow temperature is best when it is close to 60ºF.

Pot plants need plenty of sun to grow too. But indoors they will be shielded from Old Sol. To substitute for the sun, a wide choice of grow lights is available on the market, making it easy to meet your growing needs and your budget.

Whether you want to raise cannabis commercially for profit or are looking to grow some bud for recreational fun or medical marijuana for good health, setting up and using a grow room offers lots of advantages. Unlike growing marijuana outdoors, raising it indoors in a grow room allows you to control all the crucial conditions that affect its growth, like temperature, light, nutrients and water. In addition, growing weed indoors will keep it away from destructive four-legged pests like rabbits and deer who may want your crop.

You will also want to be sure to provide your plants just the right amount of fertilizer. Many commercial fertilizers specifically formulated for cannabis are on the market. You can also mix your own with fertilizers high in nitrogen, phosphorus and potassium. If you do have a drip system set up, fertilizer injectors will help you as well.

Watering Cannabis

Just like people, plants do their best in a particular temperature range. Generally, pot plants in their vegetative stage prefer a temperature in a range from about 68 to about 77 degrees Fahrenheit. When they are flowering, cannabis plants like a range of about 65 to 85 degrees Fahrenheit. They can live in lower and higher temperature, but since you can control the heat simply indoors, why not give them what they want for maximum growth and potency?

Also consider humidity. Depending on the stage of growth, pot plants generally like relative humidity from 40% to 70%. Conditions that are too humid can lead to disease, molds and fungus. Extremely dry conditions can retard the growth of your pot plants.

In addition to high summer temps outside, grow lights themselves can cause excessive heat. If you are battling high heat, look for lights that emit less heat. In addition, you can use fans or portable air conditioners to cool your grow room to the proper temperature.
