With the legalization of the Cannabis industry to grow it for medicinal and recreational purposes, its cultivation without the sunlight in the indoor environment gets popular among home growers and hobbyists in the world. No doubt, cannabis was under cultivation for thousands of years as a fabric crop which, now emerges in its new form as a stable, recreational, and medicinal crop. Growing cannabis indoor emerges as a phenomenon during the last two decades where growers need to regulate several factors for establishing a good crop stands.
Several indoor growers keep their efforts to regulate humidity and temperature in the growing environment where they install several heating devices, ventilation, and air conditioning systems without integrating with the required conditions that suit plants\’ growth. Plants need variable temperature and humidity during different stages of the growth, where conventional air conditioning equipment couldn\’t manage to regulate indoor moisture needs, and they additionally install dehumidifiers to evaporate moisture load.
Installing a small grow room air conditioner is also a common practice for indoor cannabis cultivation. Initially, such practice fails to regulate the precise humidity and temperature and become a burden in the shape of maximized electricity bills due to a lack of information on the power consumption and the area which grow room air conditioning cover.
Indoor environment regulation only suits well if it could minimize the power consumption of all operating systems. Which, in turn, provides an optimal growth environment for indoor plants, especially cannabis.
The confusion while installing an HVAC or only a portable air conditioner for the grow room arises when the growers have limited information about such systems, their electricity consumption, and the growing conditions and agronomy that cannabis needs for its growth and development. Since the growing practices continue in the tight spaces in urban areas, it becomes important to know the right growing conditions besides knowing the cooling equipment that suit to all sort of indoor growing spaces of varying capacity.
Only a well-balanced equation on both cannabis potential growth and the systems that help us to regulate indoor growth environment is important. The grow room air conditioners could lower heat, ultimately reducing the humidity, which is an outcome of heat produced by the lights installed to keep up cannabis physiological processes. Here are a few features that every grower needs to check before buying a grow room ac unit or a portable ac for the grow room.
Features to Study When Buying Air Conditioner for Grow Room
#1 Air Conditioner Types
If your grow room measures around 500 square feet, then it is advisable to install a split type air conditioner as a permanent fixture. Window ac for grow room is also another option for a permanent fixture. But, a portable ac for grow tent or small grow room meets the entire humidity and temperature needs for growing cannabis.
#2 Cooling Vs. Coverage
The cooling power of the air conditioner measures in BTUs. The higher the BTU\’s more area it will cover and the more power it consumes.
#3 Weight & Size
Whatever the type of your air conditioner is, it should meet the growing requirements of your cannabis. Moreover, mounting at a suitable location according to weight and size is also preferred.
#4 Energy Efficiency
Also, consider the Energy Efficiency of your grows room ac units. Air conditioning units with greater EER are more prolific and efficient.
#5 Hot Air Exhaust
Often, air conditioners release hot air during the cooling process. Look for the proper air exhaust arrangements so that the hot air gets out of the grow room sufficiently. Air conditioners with dehumidifying features could keep the grow room cooler compared to the conventional AC\’s.
#6 Voltage
Check electricity volts that your power distributor supplies to your site. There might be a regulator to switch between the volts supplied.
#7 Performance
Be sure that the selected air conditioner holds the following additional features for your ease and plants\’ comfort. Heating options for winter, a switch for regulating grow room temperature and humidity, remote control, multiple fan speeds, and a timer to run the system for desired intervals.
#8 Easy to Install
Grow room air conditioners need periodic air filter cleaning and draining, in case you install a portable air conditioner. Be sure that the selected units are easy to install, mount, and maintain.

Melinda Purewise. From Canada. We ordered the girl scout cookies. These plants are actually a hybrid of the auto flowering plant, the girl scout cookies. They are more or likely the same as the feminized version. They are however easier to grow and this is also what we experienced! Girl Scout cookies are perfect indoor plants and flower within 8 to 9 weeks.
Matthew Wardin From USA. For my condition I ordered the CBD critical mass cannabis seeds from Dr Seeds. These seeds are the best for people with chronicle pain. After severing in the US military and my leg condition afterwards, the CBD critical mass has been the best for me ever since. The CBD plant is actually very large and contains around 6-8% CBD. Dr. Seeds even send me 2 samples to try for my condition, and they have been very helpful ever since. Great seed-bank!
