There are pros and cons of using each one of these sources for fresh air but the point is, open loop systems will have new, fresh air continuously pushed or pulled into the grow space. Marijuana plants require fresh air to grow well. Some carbon filters can be refilled while others must be completely replaced. We prefer using the exhaust to push out old air. Ozone generators can be used both inside the grow room to maintain air quality or inline with the exhaust ducting. Using these ports to control where good air comes from and bad air goes is important. "The Dangers of High Humidity in Your Home." Fans or hydroponics-grade dehumidifiers can lower humidity levels. The hot air extracted from the room is then exhausted to the outdoors via a hose. But when the heat of summer truly hits, sometimes your best bet is cranking up the AC. Your grow room design will fall into one of two categories, which need to be defined before going further into this subject - Closed Loop vs Open Loop ventilation.

In fact, it is recommended to run CO2 in grow rooms with temperatures in the upper 80’s F to low 90’s F to allow for greater transpiration. If humidity levels are too high, mold and mildew can prevail. BetterGrow Hydroponics offers over 3,500 hydroponic supplies to help you grow bigger, better and more productive plants. Seedlings of most plants tend to prefer daytime temperatures between 68 degrees and 77 degrees Fahrenheit and 62 degrees to 72 degrees Fahrenheit when the lights are off. A fluctuation of 5 degrees Fahrenheit is ideal and 10 degrees Fahrenheit is maximum.

This portable air conditioner can cool a room up to 350 square feet and, unlike a fixed window unit, can move with you from the dinner table to the living room to the bedroom. In rooms with intense lights, adding CO2 to the atmosphere allows the plants to use more of that light and increase photosynthesis. Venting is your friend – Hot air should vent out of the grow space if heat is a problem. Typically, open loop systems do not require an air conditioner or dehumidifier. A fan collects air from the surrounding area and pulls it into the dehumidifier. The activated carbon will absorb odor particles and other molecules from the air passing through. © 2011-2021 Hydrobuilder.com - 312 Otterson Dr STE D , Chico, CA 95928 USA. Most plants require a higher humidity level during the growth period because the root system of younger plants is smaller and not as developed. Is also critical to the growth and development of plants. CO2 monitors will continually measure the CO2 in the area and open the regulator when levels drop below the preset amount. Everything else is much less important. It is also important to balance the flow in and out of air.

For more information, check out our full guide on dealing with grow room heat! As plants get older, temperatures can increase, with the maximum temperature for most crops being 82 degrees F. One important thing to note is that temperatures should not fluctuate too much between day and night cycles.

The presence of mold in an HVAC system is a common complaint. As you become a more advanced grower, you can start manipulating VPD, also known as vapor pressure deficit. This is a better choice compared to using the dehumidifier, because that leads to higher energy consumption. This fan will pull air from the room through the activated carbon filter, which ‘scrubs’ the odors. Proper temperatures can also reduce the risk of mold and mildew. This inverter AC has a wide-angle deflection mechanism that spreads cooled air far and wide across all of 150 sq ft. Also, not to mention that the copper condenser coils allow maximum energy efficiency and this reflects in its low power consumption. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. You need high powered lights in order for plants to take advantage of this extra CO2.

Always water your plants when the lights are on so they can evaporate most of it during the day. When plants transpire (exhale) they release excess water and without proper ventilation, the excess water in the air has no place to go which can cause your plants to remain soggy and become susceptible to mold. Carbon filters have cubic foot per minute ratings (CFM) which tell you how many cubic feet of air can pass through the filter while still providing an adequate scrubbing. We're here to make sure you get what you need to maximize your harvest. The dehumidifier reheats the air and exhausts it back into the room. After the timed exhaust fan is activated, and has removed all of the heat, humidity, and excess Co2 -- a Co2 generator will produce the gas until its ppm level reaches the desired level for growth. Ducting components refer to their throughput performance as ‘cubic feet per minute’ or CFM. The “size” of a dehumidifier actually refers to its capacity—that is, how much water it can pull out of the air in a 24-hour period. You can find replacement MERV 13 filters here. Either an intake fan that pulls air  from an outside source, or a passive exhaust system pulls in fresh air by forcing old air out through an exhaust duct. The Co2 that’s injected or generated within the room will always be removed or diluted, and will prove useless. Orders can be placed 24 hours a day at www.sylvane.com.

They can be installed very easily to any grow tent or grow room. Ozone generators can be hard on human lungs. The exhaust within the grow room is controlled and is only used when temperatures rise to an unsuitable level, the humidity is too high, or the Co2 levels have risen to an unsafe level.

Growers using more than one light shouldn’t consider this an effective method to control odors. For example, a RH of 50% at 90 degrees means the air is only half “full” of moisture. Relative Humidity (RH) is the measure of how much moisture is in the air at a given temperature, compared to how much moisture the air could potentially hold at that temperature. This is because the air within your grow room is constantly being replaced. Carbon filters become ‘activated’ with oxygen which open up pores on the carbon located within the filter. As the air passes through, it comes into contact with the dehumidifier's cooled coils. Rooms with humidity above 70% will lessen the lifespan of the carbon filter by as much as half. Temperature can be taken with simple analog or digital thermometers. If you are using lower powered grow lights such as CFLs or fluorescents, there is most likely plenty of CO2 available for your plants and it will not help to add more CO2 to the atmosphere than the plants can use. Fans only push air around – It’s a common misconception that fans bring down the temperature, but fans don’t cool the air. Several thermometers should be placed various locations in the growing area and always measure temperature in the shade. Temperature will depend on the kind of crops and growth stages being grown.

However, if you have a quality grow light but the atmosphere in your garden is toxic, you will not grow anything. That means you need a constant stream of air flowing into your growing space. CO2 is already found in the air -- natural concentrations are about 400 ppm. If the 40% basement relative air humidity can guarantee the absence of mold growth, all the electricity needed to bring relative humidity from 40% to 30% would be wasted (or would be of no consequence as far as mold growth is concerned). This is because the air within the grow space is constantly being replaced so heat and humidity do not have a chance to build up. Open loop grow rooms consistently provide fresh air to the plants in one of two ways. The amount of water vapor in the air can vary. Typically, growers will not add heat or humidity to a grow room because these elements are prevalent byproducts from the grow lights and plants themselves. So, if we have a 10x8x8 room our total area is 640 sq/ft. A dehumidifier is a box that contains cold evaporator coils, warm condenser coils, a fan, and a reservoir or drain to catch water.
