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). Here you can see images of the finished setup(s). The style of the buckets may vary depending on the materials available, but their function is the same.
Space Buckets are easy to make, and require readily available items for construction. Total investment is about $100, depending on what materials the user can recycle. You can see a rundown of costs (including seeds and nutrients) in this thread from the community. You can also take the next step with the DIY guide.
