If the plant has many bucket tops, the canopy will surely be under more heat, as the ventilation is generally at ground level. In this case, a third PC fan can be added to a bucket top for more mobile ventilation. A standard 1A 12v power supply should be able to run three fans, depending on their amperage usage; if it doesn’t work, the active intake at ground level can be disabled.

Once the fans are in place, connect the 12v power supply to them.

This allows you to adjust your lights easily as your plants grow.

6 x 23w CFL bulbs and the same number of E27 sockets
(more light is better up to a point, but heat is also a concern; using 6 small CFLs gives the best of both in a space bucket)

Step 5: Cut off tops from all buckets except one, and stack them on top of each other to give your bucket adjustable height

The image below explains the procedure:

Here’s the design I originally used for Space Bucket lids, though I’ve found the following design is far superior:

Step 2: Create Your Exhaust System (Intake & Outtake Holes with fans)

Pick a bucket lid and make holes for the bulb sockets. Wire them in parallel with cable and a plug. Here’s a diagram I made on how to wire your lights in parallel for your space bucket.

These will hold the PC fans (8×8 or 12×12) so you will need to cut them to size. It’s best to have a tight fit and apply some pressure, as bucket walls bend.

The winter in Boston is long and cruel, and it’s lingered this year into a dismal gray spring. Back on the South Shore, as we watch the artificial sunlight spill out from John’s bucket, I’m overcome by the illogical urge to climb in, hunker down and bask in its warm brightness until the weather warms, the days lengthen and greenery creeps back into the landscape.

The concept is undeniably elegant. Cannabis isn’t a difficult plant to grow, but it is notoriously picky about lighting. Unlike a closet-grow setup, which can call for hundreds of watts of power, a well-built space bucket reflects nearly all the light output back to the plant, and many growers have eked out defensible harvests with just 100 watts of LED or compact fluorescent lighting—with an electric bill uptick of just 10 or 20 dollars, depending on local rates.

“My first plant failed to grow because of the little sunlight I got in my apartment,” Ekrof said in an online interview. “That is when I decided to add a CFL bulb to the lid of the bucket, and a couple PC fans to keep the air running. This basic design turned out to be very effective and easy to tweak and upgrade.”

In the finished basement of a rambling green home on a sandy residential street a stone’s throw from the blue-gray ocean of Massachusetts’s South Shore, John is ushering us down into the cramped bedroom closet where he keeps his space bucket.

Outer Space

And if you’re not handy with tools, there are signs that a cottage industry has started to spring up of artisans who build and sell their own space buckets. CJ Cummings, who sells artisan space buckets through an Etsy store called MostlySafe out of Portland, OR, says that he sold about 20 units last year for $275 apiece, and hopes to move more going forward.

“It’s like playing God, man,” he says with a grin. In fact, John and a few friends are currently planning an experiment in which they’ll set up a handful of space buckets with identical conditions so that they can change one variable—the hours of light they give the plant during the flowering phase, say—and lab-test the potency of each harvest afterward to expand the knowledge base of effective indoor-growing praxis.

Step 3: Cut the bottoms off two more buckets to create spacers to add height when your plant outgrows the first bucket. The 5-gallon buckets should nest perfectly, so no light should escape when the buckets fit together. Save the bottom of one of the spacer buckets to catch drainage.

Bucket Yields

There’s also a certain erudition. John affects a Boston folksiness, but as he speaks confidently about vapor pressure, density and soil acidity, it becomes clear that he’s a deeply experienced gardener with a citizen scientist’s enthusiasm for documentation and experimentation—and that part of the space-bucket ethos that drew him in is the opportunity to control every input a plant receives.

John, who asked us not to use his last name because he’s a small-business owner, is a member of a spirited new subculture of home growers who have congregated online in recent years to share information about—and instructions for building—tiny grow chambers cobbled together from 5-gallon buckets, totes, plastic barrels and materials you can buy at Home Depot or Lowe’s. They call them “space buckets,” and draw inspiration both from traditional closet growers and the hacker-inflected maker community, where the open-source taste for sharing knowledge and designs is deeply ingrained.

I am new at this too and am gearing up for my first build and grow cycle

Thanks for the reply. Would you recommend LED lights or fluorescent ?

Cost: Depends on type of lights used and time lights are on with some Power Companies (pricing differs at night)
