When you choose to water your plants can also help with absorption and prevent heat problems. To help keep your plants hydrated, water in the early morning before the sunrise and late in the evening after sunset. When you water at these times, your plants are better able to absorb more of their water because it does not evaporate as quickly.

Placing your plants in the shade can also help; however, you should only do this for the occasional heatwave. If your plants are not regularly exposed to direct sunlight, they may go into shock when they eventually are exposed to it. This includes moving your plants that are growing in containers.

Soil temperature and marijuana plants

However, if the temperature is above 85ºF during the flowering stage, bud growth will be stunted, which may result in an airy and loose bud. The potency and smell of your buds may also be reduced. Maintaining the right temperatures during the flowering stage is crucial if your goal is to produce densely packed buds.

Here are some marijuana strains that thrive in hot temperatures:

Indoors

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

High humidity levels are a problem for marijuana plants. Excessive humidity can slow your plant’s growth, encourage the development of mold, or even cause root rot. That doesn’t mean your plants want a desert environment, either. Excessively low levels of humidity can stunt growth and cause stress on the leaves.

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.

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.

To help you get the most out of your pot-growing efforts, DripWorks has put together some basic tips to help you achieve the ideal grow room conditions for growing cannabis indoors. Whether you are growing one marijuana plant or a thousand, these ideas for perfect grow room conditions should help you get the most out of your efforts.

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?

How to Get Sunlight & Fertilizer for Indoor Cannabis 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.

Water is a crucial element of life, and pot plants are no exception. They need adequate amounts to thrive. Growing plants inside, you will need to provide a steady supply of just the right amount of H2O. You could hand-water with a hose or a bucket, but that is a time-consuming and inefficient process. A good drip irrigation system can deliver just the right amount of water to each of your plants efficiently and reliably.

If you need to increase the temperature, you can use a variety of traditional heating options, including electric, gas and other sorts of heaters typically used in homes or commercial buildings. Heat lamps and insulation are other possibilities, while heat mats underneath containers can warm the soil. In larger spaces, a fan can help circulate warm air so all plants can benefit from it equally.

Watering Cannabis

A grow room might be as small as a closet or as big as a barn. No matter the size of your grow room setup, you want to pamper your plants for maximum growth and strength.

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.

The drying room is a place that must be carefully monitored. Keep in mind that your plants will be giving off a large amount of moisture into the room as they dry. It’s important to pull wet air out and keep air circulating in the room without actually having fans blowing right on your hanging branches, which can dry them out prematurely resulting in a harsh taste and burn. Also, growers in dry places such as Colorado struggle to extend their drying time with humidifiers, while farmers in more humid climates such as Northern California use dehumidifiers to pull water from the air in order to avoid mold growing on their buds.

Because cannabis cuttings root best in warm conditions with high humidity, the cheap trays with clear plastic domes work remarkably well. In cool conditions, a heat mat should be placed underneath the trays to maintain an optimum temperature of 74-78 degrees F. and relative humidity at 75-85%. No matter where and into what medium you plan to root your clones, keep warmth and high humidity on your priority list. Clones allowed to get cold or dry will perish quite quickly. Too much humidity (over 90%) can also cause mold and rot, so cut a quarter-sized hole or two in your clear plastic dome to allow some air movement and circulation.

Garden temperature is a critical factor in photosynthesis and plant development.

The best grow room temperature during the vegetative stage of growth is 70-78 degrees F. when the lights are on during the “daytime” and no more than 10-15 degrees cooler at “night” with a relative humidity of 45-55%. With these settings, your plants will best be able to convert light into energy for growth. This is the time when the plant puts on leaves and branches and expands it’s root system throughout your growing medium. If it gets too cold or hot, growth stops and you eventually risk losing your plants altogether.

The Flowering Stage: Best Grow Room Temperature

The best grow room temperature during the flowering stage of growth is 68-75 degrees during the day and no more than 10-15 degrees cooler at night. If you’re supplementing with CO2, daytime temps can be as high as 75-82 or so. During flowering, you should lower your relative humidity to 35-45% and even lower (30%) for the last couple of weeks before harvest. This will help you avoid issues with mold, bud rot and PM (Powdery Mildew) that can arise in higher humidity.

Ideal grow room temperature and humidity varies depending on the stage of plant life. Cloning requires higher temperature and humidity than vegetative growth and flowering plants have different ideal atmospheric conditions as well. In order to master the art of marijuana growing, dialing in the proper environment at the right time remains the most essential ingredient for success. So, what is the best grow room temperature and humidity level?

In order to properly measure temperature and humidity, you’ll need a thermometer and hygrometer. Best to invest in a digital one that can give you current readouts as well as highs and lows when you’re not inside the room. To raise heat, you’ll need a heater and to lower heat, you’ll need an air conditioner. These can be outside or inside the growing space depending on the size of your space and how much the temps and moisture levels fluctuate. A humidifier and a dehumidifier can be employed to raise and lower humidity rates. Larger grow rooms can benefit from a controller that uses a sensor to keep track of temps and humidity and turns on the appropriate appliance to regulate and keep them within your set parameters.

Cloning

The ideal temperature for a drying room is between 65 – 74 degrees Fahrenheit and humidity between 45 – 55 percent in a dark well-ventilated room. Cannabinoids, terpenes, and flavonoids can evaporate and be released at temperatures above 80 degrees, diminishing the scent, flavor and potency of your buds. Within 6 – 10 days your branches should snap instead of bending and the buds should feel popcorn dry on the outside. This is the time to cut the individual buds from the branches and put them into glass jars to begin the curing process. Cure your buds in a cool (68-72 degree F.) and dark place.
