Building an upside down planter for tomatoes and cucumbers is easy to do. You could make as many planters as you have space for and have a vegetable and fruit garden even if you live in an apartment complex with no garden space available. If you have a place for a few hooks, you can build the topsy-turvy planters yourself and have fresh vegetables and tomatoes from your own garden.
Set the bucket on a table with the open end down. Drill a 3-inch hole in the bottom of the bucket.
Drill five 1-inch holes around the side of the bucket about 3 to 4 inches from the bottom of the bucket for air flow.
Place the cucumber or tomato plant through the hole in the bucket, making sure not to damage the green foliage. Hold the plant in place with one hand and use the other hand to pour soil into the bucket, packing the soil lightly around the plant roots.
Fill the bucket with soil until it is 3/4 full of soil. Gently pack the soil down.
Drill five to six 1-inch holes in the cover. Place the cover on the bucket. Water the plant and soil through the cover.
Hang the bucket on a hook somewhere where it will get the sunlight it needs to grow.
