Root Zone: 5 gallons of potting mix.
Reservoir: 1.75 gallons of water.
The Best 5 Gallon Bucket Planter:
THE DOUBLE BUCKET ADVANTAGE: Some self-watering bucket designs only use a single bucket which is then partitioned into a potting mix section resting above a smaller water reservoir. Those designs can save you a couple dollars since you don't need a 2nd bucket. But they reduce the water storage capacity along with the available root zone. The double bucket SIPs allow for even larger plants while boosting hydration significantly.
INCREASED WATER CAPACITY HACK: The hack shown in the video gives an even further boost, allowing you to have a much larger water reservoir. These wicking buckets are quite sturdy when filled with water. But the plants can get massive! If your crop is super tall and you tend neglect the water reservoir, you can maintain stability by adding a brick to the reservoir. I personally don't need to do it since I keep the reservoir fairly full. But if your garden is in a super windy area, you might decide to play it safe, especially once your plants start to explode. 😉

What to Grow in 5 Gallon SIP Buckets
PORTABLE SELF-WATERING POTS: These wicking containers are compact and easy to move around. That makes them perfect for renters or gardeners who want to grow plants on their porches, decks or balconies. A perfect option for first-time growers or for handling an overflow of plants.
A self-watering 5 gallon bucket is a fairly robust system capable of going for days or even weeks before needing watered. The soil capacity is large enough to yield a fairly nice harvest. A single tomato plant will do pretty well or even a squash, cucumber or zucchini. I think these containers are perfect for a couple pepper plants or a single kale or broccoli. Obviously, smaller things like carrots, lettuce, spinach or basil will grow super well.
