Closet Grow Light Setup – Growing Plants In Tight Spaces

by | Jul 27, 2023

Establishing a closet grow setup has never been easier, cheaper, or more practical. That’s thanks in no small part to advances in so-called vertical farming. These and other related innovations have made the necessary equipment more streamlined, readily available, and less expensive. With that, an indoor grow closet setup is simple to create, affordable, and takes up just a closet-worth of space, as the name suggests.

Not everyone has a huge budget nor a spare room, garage, or other outbuilding to dedicate to plant cultivation. With that, closet grow setups have always been popular. And now, setting them up is a breeze with a modicum of knowledge and, of course, the right equipment.

Benefits of Closet Grow Setups

So, why set up a closet grow space versus the alternatives? For many, the benefits are plentiful, including, but not limited to, the following:

  • Less costly than a grow room
  • More discreet than a grow tent
  • Ideal for lower-volume production
  • Cost-effective to set up versus alternatives
  • Facilitates growing plants in tight spaces
  • Highly energy efficient using LED lighting
  • Easy to install and later dismantle
  • Works in almost any closet

Growing plants will work in almost any closet, including built-in and freestanding units. While the benefits are clear, there are one or two unavoidable drawbacks. Namely, that’s limited room. However, there’s no better option for growing plants in tight spaces at home.

Furthermore, limited growing space often isn’t as big of an obstacle as it may seem. More on that in a moment, including roughly how many plants it’s possible to cultivate in even the most compact closet spaces.

Indoor Grow Closet Setup

Having decided on an indoor grow closet setup, it’s time to start the build. Whether using a built-in closet or a freestanding unit, the space on offer will determine what’s required. That’s in terms of how much lighting is needed and how many pots are necessary. It’ll also determine how much—if any—insulation material is called for.

Don’t worry about a closet being too small. Even a space with a footprint of just two feet by three feet and measuring only four to five feet high is sufficient for many of the most popular, widely grown at-home crops, like microgreens. Take marijuana as another prime example. In a space of this size, there’s typically enough room for three average-sized adult cannabis plants.

Choosing smaller plant strains or varieties is often advisable where space is limited. Aim for ones short and bushy, regardless of the crop in question. For marijuana, an excellent example would be Royal Dwarf.

Indoor Grow Closet Must-Haves

Closet Grow Light

A closet grow light setup will ultimately determine the system’s success. Opt for a slimline model – one with a compact form factor. Most LED light units meet this criteria. That makes them far less bulky than many of the alternatives in widespread use in the past, like lights with incandescent bulbs.

Insulation

Temperature is all-important for growing any plant crop. Insulation allows growers to maintain this while limiting excess heat escape into the surrounding space. Also, insulation doesn’t just keep heat in. It also serves to maximize lighting output. That’s as it reflects light toward the plants rather than seeing it absorbed into, in this case, a closet’s walls.

For insulation in a closet grow, Mylar® polyester film and similar products are popular. Where managing heat transfer is less of a priority, and it’s more a matter of maximizing light output, simply painting the inside of a closet white can also have a similar effect.

Ventilation

Ventilation reduces excess humidity, provides plants with life-giving fresh air, and helps to eliminate odors. A grow closet ventilation system can be as basic or complicated as necessary. That includes installing multiple hard-wired intake and exhaust fans or opting for more rudimentary provisions like ensuring manual airflow. Where minimizing any odors from a closet grow setup is a priority, carbon filters are advisable.

Space-Saving Pots

Any plant-growing setup will call for plant pots. However, where space is at a premium, such as in a closet grow space, choosing the right pots for the job is paramount. For example, opting for square plant pots saves wasted space and allows for raising more plants in close proximity.

Watering System

Like light, plants also need water for survival. Second only to lighting, then, is watering. These requirements are made infinitely easier by installing a watering system. This system needn’t be overly complicated. Alternatively, regular daily watering with a watering can or suchlike will usually suffice where more complicated provisions aren’t an option for one reason or another.

Drainage System

As with a watering system, built-in drainage will make growing plants in tight spaces a breeze, particularly in a closet. Again, this can be as straightforward or complicated as necessary. In the simplest sense, allowing excess water from plants to drain into a tray works. This surplus water is then easily transported away in the same tray or via one or more buckets.

Thermometer

One possible downside to a closet grow setup stems from among the most significant benefits. That’s because the small spaces cleverly being utilized can quickly become too hot or too cold. Monitoring the temperature with a suitable thermometer is crucial to mitigate the risk of plants suffering from fluctuations. Thermometers aren’t expensive, and adding two or more in different parts of a closet is often advisable to allow for more accurate gauging of overall temperature readings.

Hygrometer

Akin to a thermometer, a hygrometer, used to measure water vapor levels in the surrounding air, helps ensure and maintain optimum humidity requirements.

Tools and Other Considerations

If mounting light-hanging brackets, installing insulation material, or creating holes for ventilation purposes, a tool kit including at least a drill and an electric screwdriver will almost certainly make things easier.

Most crucial of all, though, is that all-important lighting. Of course, closets get no natural light. Therefore, supplemental lighting isn’t optional – it’s a fundamental requirement, just as it is in significantly boosting growth rates in greenhouses and other plant-growing operations.

How to Setup Closet Grow Light

With the importance of lighting established, setting up the necessary provisions to achieve optimum results is similarly crucial. Invariably the best lighting option for any closet grow setup will be LED-powered. LEDs are more slimline, produce less heat than alternative options, and boast numerous other benefits for a closet grow light setup.

For any LED closet grow setup, when pertaining specifically to the lighting, refer directly to the manufacturer’s instructions. Bata is one such manufacturer. The company is a leading global producer of grow lights, and every unit ships with a comprehensive manual and user directions. When choosing Bata grow lights, always use this manual and the enclosed instructions to perfectly optimize any new LED closet grow setup at the point of installation.
