In North America, grow tents are typically thought of as good cannabis cultivation solutions for the small-scale home grower. While this may be true, tent growing is also great for commercial-minded growers who frequently switch locations. One of the great things about tent growing is that once you develop a good system, it's highly transferable. This gives savvy growers the opportunity to produce cookie-cutter results and the ability to move on without anyone ever knowing you were there.
The first grow tents available for sale came out of Germany. Before tents, growers needed permanent construction to cultivate buds, which often included drilling into ceilings and walls to hang or mount heavy equipment. It also meant that floors are susceptible to damage from watering spills and more.
A grow tent comes in just about any length and width. Some even allow you to customize the shape and are built sturdy enough to safely hang equipment like carbon filters or heavier air-cooled lights. Be sure to read the instructions carefully: you need to know exactly how much a tent is designed to hold before you hang gear up.
Aside from offering waterproof flooring and the ability to avoid any construction on the room or building, grow tents also make very efficient use of crop lighting because the interior is so reflective. Beginner growers should not underestimate the extra bud gains from having your crop surrounded by material that reflects and diffuses light back to the crop.
While these are great traits or the smaller home grower, what about those who like to go a little bigger?
If you add a lung room to the equation, you can run your ops completely sealed and produce consistent and replicable results in each of the tents you attach to the central lung. In each of the grow tents that is connected to the lung, there should be a dehumidification system, a carbon filter and fan-sending air back to the lung room.
In the lung room the temperature should be set to 75 degreesF. So when the combined air becomes too warm (remember the tents are all connected via lung room) the AC kicks on and cools. CO2 levels are maintained in the same fashion; typically set at 800 PPM (parts per million). When the lights are off in any one of the tents (air-cooled lighting is recommended), the temperature is typically around 75 degreesF and when on the temps are usually about between six and ten degrees warmer -- once you get your fan capacity and ducting diameters dialed in, that is.
This type of set up allows you to grow on any scale, adapting your garden as needed while affording your grow mobility.
