A classic Space Bucket garden has enough room to fit exactly one plant. The smallest kind of buckets to build Space Buckets are of the 5gal variety. This size of grow bucket has a very small footprint and it is perfect for one plant indoor gardening. They are specially suited for Auto seeds, as these plants are easier to train and stay naturally shorter inside the container.
LED heatshinks should be installed on the outside of the container when possible.
UFOs come with a plug for easy installation, and they have fans on the back. There are many UFOs available, but most are rebrands of generic products from China. You will find them in 90w, 135w and 180w, all of which can be used in a Space Bucket.
