“1st time grower. Plants are 1 month old, and 12″ tall now. Set up for less than $250. Used cab.w/4 bulb, 24″ T5’s, 4″ elec exhaust, Thanx for great info.”
Sirius: Google SketchUp can be pretty tough to use without training, especially if you’ve never used it and you just want to design one thing. Rest assured: some paper, a pencil, a little math, and careful planning will work just as well!
See Another Stealth Grow Cabinet in Action and Build Your Own!
Keeping a door open is not a viable option for the stealthy gardener like me! I decided to use some creativity.
Of course I wanted to filter the intake air to keep out dust, pet hair, pollen, mold and the like.
I installed a sealed fan room to house the 6″ inline fan mentioned above. This sat in the top inside of the cabinet, pictured below.
Sirius: This is a great point! In any enclosed grow area such as a tent or grow cabinet, it’s important to have a larger opening for intake than for exhaust. This will maximize the efficiency of your fan in addition to keeping it working for longer. Plus, this will keep tents from “bowing” in, reducing your grow space.
Final Harvest Weight: 264 grams (9.3 Ounces)
After the initial investment, $1.64 was my total cost per gram when I factored electricity, carbon filter, and nutrients.

The cord for the fan should also be fed out of the grow box. But instead of connecting it to the timer, plug the fan cord into a separate outlet so the fan provides ventilation at all times — you don’t want it to go off. Also, note that a carbon filter may be attached to the fan for odor control.
Other light sources, including compact fluorescent lights and high-intensity discharge (HID) options such as high-pressure sodium (HPS) and metal halide lamps, can also be used. However, the higher heat output of HID lights, and their need for an external ballast, make these options less practical for a grow box. Whatever lighting you choose, be sure that it is hung securely. Feed the power cord for your light outside the box through the port. Plug the cord into the power source with a timer to give your plants the appropriate light cycle.
Grow for It!
At the top of the cabinet, install a fan to push warm air out of the grow box through a ventilation port. Near the bottom of the box, install another ventilation port, which should be about twice the size of your fan to ensure a good flow of air through the plant canopy and out the exhaust port.
Ventilation: Plants Need to Breathe, Too
Once you’ve decided on an area or item to convert into a grow box, you’ll have to make some modifications to ensure your plants have a healthy environment. Cut some ventilation ports in the box to cool the space and so the plants can have fresh air. You’ll also want to make sure there’s an extra, smaller hole to funnel in electrical cords, because you’ll definitely need a light fixture and ventilation fan — both of which need to be plugged in.
Building Your Own Grow Box
Not everyone has access to a suitable and secure plot of outdoor land. That’s why many gardeners will opt to grow their plants indoors, instead. But top-quality cannabis can’t be grown like an ordinary houseplant. The flowering time for most cannabis plants is dependent on a long period of darkness, so you’ll want to give them their own dedicated area. Many home gardeners use an extra room or closet, but if you can’t spare that kind of space, a grow box may be the answer.
Note that the lights and fan should be fastened to the top of the box to ensure that all wires are safely kept away from water. To suspend the lighting and ventilation equipment inside, hooks can be screwed securely into the ceiling of the grow box. Be sure to put a large, shallow tray on the floor of the cabinet so it’s water-safe. For added security and to discourage prying eyes, a lock can be installed on the door, if deemed necessary.
Not everyone can grow weed in their front yard. If you want to manage a small cultivation op on the down-low, consider a DIY grow box.
