The idea is to use 5 gallon buckets during the entire life of any plant: this indoor garden is composed of one main bucket with soil and ventilation (two or more PC fans), and multiple stacked bucket tops for added height, if needed. Inside walls are covered with reflective material, outside walls with black masking tape, and the lid (or top) has four CFL bulbs (≥23w).
To build this indoor garden you don’t need to find anything special, just the following common items. The shopping list below serves as a starting point for one basic CFL Space Bucket:
- At least four 5gal (20L) buckets, and one lid.
- At least three 23-27w CFL bulbs, with their E27 sockets.
- Optional: 42w CFL bulbs may also be used.
- Two PC Fans and also a 12v power supply.
- Any kind of reflective material (like Mylar).
- Optional but recommended: Black masking tape.
- A nice power strip with surge protection.
- A standard 24h timer.
- Some wire, glue and other minor tools.

Space Buckets are easy to make, and as you see require readily available items for construction. Total investment is usually about $100, depending on what materials the user can recycle. You can find product alternatives on the front page suggestions sidebar.
You are also welcome to make suggestions or ask questions about the buckets using the site-wide open board. Here you can see more images of the finished product(s). The style of the buckets may vary depending on the materials available, but their function is the same.
