How to keep grow tent cool? Growing plants indoors is a great way to extend the growing season, but it can get hot in those grow tents! But don’t worry, in this article there’s some few guides to keep your grow tent cool! Read this article until end to know more about it. In this blog, we also have an article about how to use grow tents that you might want to read about it.
How To Keep Grow Tent Cool
Grow tents can be a great way to grow plants indoors, but the heat can be unbearable. Here are some ways to keep your grow tent cool.
Replace Incandescent Grow Lights With LED Grow Lights
If you’re still growing with HPS or MH grow lights, the time has come to upgrade to LED. Or, at a minimum, to CMH. If you’re just getting started, forget about HPS or MH.
The newer LED grow lights (and CMH as well) are absolutely superior than HPS or MH in every regard (except initial cost, though even that is fairly close these days).
LED lights use less energy to produce the same amount of light and generate less heat. Additionally, the new all-white LEDs (both COBs and quantum boards) have a much improved spectrum. Additionally, you will not be need to replace bulbs every grow or two.
Outside The Grow Tent, Place Ballasts Or Drivers
If you choose to continue using HID lights, you may partially mitigate their heat output within the grow tent by locating their ballasts outside the tent.
Due to the fact that the ballasts generate a significant amount of heat, placing them outdoors may assist. Additionally, you may dim the ballast to lessen the output of the lights and the ballast’s heat production.
This is a possibility even with LED grow lights. Numerous new styles are propelled by external forces. Both the Quantum and Spyder styles of fixtures do. Additionally, certain COB grow lights do.
If you have an LED grow light that is powered externally, you should be able to take it from the fixture and set it outside the grow tent. This may have a significant effect on the temperature within the grow tent, particularly if it is a small grow tent with little ventilation.
Circulate Air Within And Without The Tent
At the absolute least, you’ll need an exhaust fan and some ducting to do this. Additionally, you’re going to require a charcoal filter. Additionally, if you’re using a large grow tent, you’ll want an input fan.
Utilize the exhaust fan to exhaust the grow tent’s air. You could just vent it into the room, but it would cause the room to heat up, resulting in a similar scenario. Unless the room is well ventilated.
Even then, you’re better off venting the air out a window or into the attic through the ductwork. Essentially, send it anyplace it can be spread without increasing the temperature in your grow room more.
You should definitely filter this air with a carbon filter before releasing it into the world. Even though growing marijuana is allowed in your state, it is always preferable if no one knows about it.
While you may place this carbon filter outside the grow tent to conserve room, it is typically recommended to keep it within.
In a tiny tent, sucked-out air may be passively replenished through an intake vent. The intake should be located at the bottom of the tent, where cold air condenses. The exhaust vent should be located at the top of the tent for the same reason (hot air rises).
With a bigger grow tent, the exhaust fan will need to be very powerful, which means you’ll also need an intake fan that can keep up with the exhaust to draw in fresh air. Generally, the intake air comes directly from the room outside the grow tent.
Maintain a cool temperature in the room outside the tent. You’ll need to air condition it in warmer areas. Additionally, you might install an air conditioner right inside the tent (see below). Both alternatives are acceptable.
When ducting, there are a few things to keep in mind. Light may penetrate the ducts, which is a significant issue during blooming, when your plants need 12 hours of darkness each day.
To avoid this, use light-proof ducting and include a u-shaped bend at some point to guarantee that no light enters through the end aperture.
Along with light, bugs may enter via ductwork or the intake vent. Consider installing a screen over each entrance to keep them out.
