How to Build a Marijuana Grow Box

Teach someone how to fish and they can eat for a lifetime. Teach someone how to build a grow box and they can –yeah, you get it.

Often times marijuana consumers branch out and explore methods on how to grow, cultivate and tend to their own buds.

So, much like fishermen deciding between a net and pole, new growers must decide which approach is best suited for their particular situation.

Build a Marijuana Grow Box

Self-sufficient marijuana production: that’s the American Dream, right?

And although the founding fathers did in fact cultivate cannabis, they were not aiming to achieve the same botanical feats as current-day home growers. Nor were they working through the same environmental conditions.

Therefore, prior to making any final decision between a cabinet grow or closet grow setup, it’s important to evaluate what your personal goals and limitations are. Things to consider off the bat when looking to build a marijuana grow box:

  • What’s your budget?
  • Do you have room for a grow box?
  • What yield are you looking to produce?
  • How discrete do you need to be? (aka, will lingering marijuana smell be an issue?)

These questions will help you start narrowing down what equipment your specific situation requires. The area being used is a big factor when considering how to build a grow box, as it will usually determine which equipment choices are most appropriate.

For instance, if there is room available and a desire to produce a larger yield, HPS bulbs are the move. Similarly, if persistent marijuana odor has the potential to be a problem, carbon air filters can be installed to remove the smell. To put it broadly, the choice you make about equipment depends on your location, budget and growing objectives.

Closer look at Equipment

After examining what your needs are, it’s time to choose which route to take when it comes to equipment.

Here’s a closer look at equipment and parts involved when deciding how to build a grow box:

  • Lamp — What lights the whole operation. Can include the bulb, fitting and lamp reflector. CFL lights are recommended for smaller set ups, while HPS bulbs work better with larger spaces.
  • Timer — Controls and maintains light cycles.
  • Ballast — Runs the lamp and regulates the electrical current.
  • Fan — Used to set temperature within the grow box.
  • Air duct — Ventilates airflow from fan to outside.
  • Carbon air filter — Removes marijuana smell from ventilated air.
  • Mylar — Highly reflective covering sheet for optimizing light.
  • The grow box frame — For a controlled environment.

*note: these components exist, for the most part, in both cabinet grow and closet grow operations. In some cases, select equipment may not be needed.

Put it all Together

Searching for a cheaper alternative and willing to perform some light DIY work? Get started and build a closet grow. With a little creativity, the possibilities for innovation and budgeting are endless. For the DIY route, there are no exotic parts involved, just simple gardening and ventilation equipment. How to build a grow box:

  1. Construction of the box frame. Some DIYers utilize wood; some make use of strong cardboard. Whichever material you select, be sure to pick something sturdy. Build it big enough to account for the amount and height of plants, the size of the lights, and space for a fan. Oh, and don’t forget to attach a door.
  2. Completely line the interior of the box with reflective Mylar sheets to enhance the light’s strength.
  3. Cut holes (two-three) for air intakes below the plants, so that fresh air can travel up through the plants toward the fan.
  4. Cut a hole at top of the box for the air-out ventilation.
  5. Install the air duct system at the top of the box.
  6. Install a fan — attaching it to its interior and very close to the air duct opening. This will help regulate temperatures within the box (those lights get hot).
  7. Install the air filter in front of the fan, so that air moves through the filter before getting sucked through the fan, on its way to outside.
  8. Hang lamp, with ballast and fan.
  9. Closet grow ready.

Perhaps you have some extra money to invest, but don’t have time to put toward small construction projects? Examine cabinet grow options that offer the whole package with less start-up effort involved.

  1. LED SuperLocker 3.0 by SuperCloset: $1,950
  • Fireproof and very secure, includes everything needed to get started within two hours after getting the product. Three-year warranty included.
  1. Hydroponic Speaker Grow Box: $300
  • Promises to deliver an exceptional yield and comes complete with all the amenities you need to get started, while still remaining inconspicuous.
  1. The RoomMate Stealth Grow Box: quotes on request
  • Great for quality operations in small spaces, this cabinet grow features odor control, air-cooled lighting, 400w digital ballast and an automated electrical timer. It also comes on wheels.

Final Thoughts:

  • Enclosed spaces are optimal for growing because they allow for better control over the environment.
  • Each plant you plan to grow needs about 1 square foot of space
  • Expect to spend at least $300 on cabinet grow and around $200 on a closet grow.
  • LED bulbs combat energy costs but produce less yield.
  • Electricity Cost Calculator — most small home grow operations only add $25-40 extra a month to the electric bill.
  • Bulb replacements are a thing, and for HPS that can be expensive (typically around $50)
