This will include jobs in manufacturing, shipping/receiving, sales, customer service and administration. Watch A Video of the ProgressThe Best Way to Cool a Grow Room With a Portable Air Conditioner Indoor grow rooms are ideal for growing certain types of plants quickly and efficiently, because you can regulate the light, water, nutrients and safety of your plants within these rooms. However, these rooms can become quite warm because of all the light and lack of air flow, so a portable air conditioner may be required. Purchase a portable A/C unit that is the correct size for your grow room and will effectively cool it to the correct temperature. These portable A/C units come in different sizes and strengths, ranging from 5,200 BTU window units to two ton 12,000 BTU units which come in multiple parts. If you think you will be moving the portable A/C often around the grow room, then a smaller unit is most likely better.

Price also varies for these units based on size, power and reliability. A portable air conditioning unit takes up a lot of electricity, so it is essential that it have its own separate electrical hook-up. This is so it doesn't effect the grow lights or any other aspects of the growing operation. If it were hooked into the same power circuit, it might pop it, causing the lights to break, a fire to start or the whole grow room to be shut down for a period of time, which could seriously affect the plants in the grow room. So make sure you have your separate electrical line set before installing your portable A/C unit. The placement of the portable A/C unit should be in the place where the most heat is being centrally generated, in order to regulate it the most effectively. If there is a bank of grow lights overhead, then the best place for the portable A/C unit may be on the floor, amid the plants, directly underneath the grow lights, so that hot and cool merge right at the level the plants are thriving.

This may take some trial and error to figure out the optimal place for the A/C unit by setting it up and then taking specific air readings of the new average temperature. Also, observing how the plants respond to the addition of the A/C unit will help you find the best placement for the unit.

A proper air ventilation allows the plants to perform all the needed gas exchanges, along with evacuating the heat produced by the lamps, achieving a better climate control and thus growing stronger plants. The ventilation systems normally used are composed of, at least,  two or three complementary elements: the air extractor, an interior fan that moves the air of the growing space and, in most cases, an intractor fan. The extractor fan is the key element of any air ventilation system, as it renews the air and regulates the climate of the growroom. The needed extraction power depends on both the growing space and the lighting system used. The more light output we use, the more potent the extractor fan must be (this works also for the dimensions of our growing space). It’s all about perfectly matching the operation of this devices. There are several rules to calculate the power of the extractor in relation to the available space, but none of them takes into account all the different factors: light output used, volume of the growing space and outdoor temperature.

In this table you can see which extractor should be used according to the growing area and the lighting system. It is important to distinguish between conventional inline extractors – that are actually fans with blades – and industrial fans (RVK, Prima Klima ) which are industrial turbines much more efficient than the former. The difference in the airflow capacity (m3/h) between these two types of fans is enormous! In practice, inline fans should only be used when growing with energy-saving lamps and perhaps also as air intractors, as we’ll see next. If you are using HM or HPS bulbs, industrial  extractors (RVK, Prima Klima) are highly recommended. This type of extractor also allow to attach carbon filters to remove indiscreet odours from the plants. In smaller spaces, the intractor fan may not be necessary if we have a good extraction system (RVK, Prima Klima). Indeed, thanks to the effect of the pressure, the air will passively enter the growing tent through the holes on its sides (to avoid light from the outside entering inside the tent, just place a piece of bent air duct in the intraction hole).

Of course, using an intractor fan is recommended: In all cases, the airflow capacity of the intractor must always be lower than the extractor capacity, specially when using carbon filters (thanks to the pressure all the odorous air passes through the filter). Generally, a simple inline fan will work perfectly as intractor. Cooltubes are very efficient devices to lower the temperature of the growing space. With this system, some of the heat produced by the bulb is evacuated by the extractor fan to the outside. By contrast, cooltube reflectors have a major disadvantage regarding the light output, and should only be used in case of need (temperatures higher than 28 degrees celsius) since the yields are slighty lower with this devices. Indeed, the glass of the cooltube absorbs approximately 10% of the emitted light, even more if it is not perfectly clean. This loss is even larger regarding the light that reflects on the reflector, since it will have to pass three times through the glass before reaching the plants!

Finally, the reflector attached to the cooltube is usually smaller than classic ones. Some growers think that cooltubes are more efficient since they allow them to place the bulbs much closer to the tops of their plants, but they shouldn’t forget that the closer the bulb is to the plants, the smaller will be the area covered by the lamp. Placing them too close to the plants may cause that only the plants directly below the bulb will benefit from it, while the others may receive less light. The interior fan is a complementary piece of the extractor fan. While it is not a very efficient tool to decrease the temperature, it prevents air stratification inside the growing tent. The interior fan is important specially for the health of the plants, since it acts as the wind does outdoors and causes: The most common fans for growing tents are those usually used at home during summer. An oscillating fan with grid is much more useful than a non-oscillating one, which blows in a single direction. 

Most growers use one oscillating fan for each square meter. There are other interesting fans for indoor cannabis growing; some of them can be screwed to the wall, others may have a pedestal, etc. Honeywell offers a model which can be directed upwards or downwards, as well as a double-blade fan which can be used to ventilate two different growing spaces. Another interesting option is using clip fans , which save space and are very practical. We can easily fix them to the growing tent bars, or place them among our plants. Many growers use the excellent Adjust A Wings reflectors with these type of fans fixed right in front of the bulb, thus preventing the formation of hot spots under the lamps like a cooltube would do, but without any kind of light waste! It is important to use the correct fan size in relation to the size of our plants. Direct ventilation on seedlings and young cuttings is not advisable, since it could de-hydrate the tender and fragile foliage. During the first 15 days of life of the plant, we can either not use any interior fan or use it indirectly (blowing towards  the bulb or a growing tent wall).

Later on, as plants grow bigger, we will also need bigger fans to move the air of the growing space. One of the best options is using fans with speed control systems. When the lighting system of our growroom is on, every component of the air renewal system should be working with enough power to efficiently control the climate (26 degrees celsius should be the highest temperature during this period). When the lamps are off and our plants have their night period, we can decrease the airflow since there won’t be any need to reduce the temperature produced by the bulbs and the plants need less air renewal during this period. To do so, we can either reduce the power of the extractor fan using any kind of controller, or use timers to reduce the operating time of the fans, for example using them 15 minutes every hour. Never stop the air extraction system completely for some hours, since plants always need a minimum air renewal to ensure a correct respiration. The end of flowering is another crucial stage;
