Frequently Asked Questions
Q. Is the GroBucket Food-Safe?
A. Yes, GroBuckets are made of recyclable food-safe materials. The plastic is the same type of plastic that’s used in the water pipes in your home–polypropylene and PVC (Insert: Polypropylene; Fill tube: PVC)
Q. Is the GroBucket device made in the U.S.?
A. Yes, all parts of the GroBucket garden kit and the GroFern are designed, sourced and manufactured in the United States.
Q. What are the dimensions of the GroBucket device?
A. The base is 10 inches in diameter and the height is 5 inches.
Q. What kind of soil should I use in my GroBucket?
A. If you are purchasing pre-packaged soil, make sure you purchase soil specifically for growing in pots/containers–not garden soil. The name should say “Potting soil” or “Potting Mix” as these mediums use ingredients which assist in draining water.
We use the following soil recipe for our vegetables:
- One standard 8 gallon bucket of peat moss
- 1/2 bag of cow manure (or 1 full bag of mushroom compost)
- I large coffee can of vermiculate
- 3 large coffee cans of pearlite
- about 1/2 cup of lyme
- 3/4 cup of azomite
- **So, like any good cook, it’s hard to have an exact measurement, but our large coffee can is approximately 30 ounces
Q. Where does the water come into contact with the soil to to wick up to the plant?
A. The bottom of the GroBucket device is “serrated,” for lack of a better term, which allows water to enter the soil from the bottom and wick up to the plant. Also, eventually the plant roots grow down to the bottom around the device. Water also evaporates and crosses the air-gap to wet the soil on top of the GroBucket device. It is also critical to water from the top when a plant is first planted, especially small plants, to allow the system and the plant to get established. Please keep in mind some watering through the soil needs to be done periodically–if you spread fertilizer on top of the soil, watering a little on top each time helps disperse nutrients to the plant roots. Putting mulch on top is also very important to help keep the top soil from drying out.
Q. Can I use the GroBucket device in a decorative planter or put the device inside a bucket, then inside a larger planter?
A. As stated in the Amazon product description, the GroBucket is designed specifically for use in 5-gallon buckets. Some people try to use them in decorative planters with bottom diameter less than 12 inches, but may have issues. Keep in mind that if your planter has a hole(s) in the bottom for drainage, like a standard plant pot, the water will drain out immediately and defeats the purpose of the device creating a gallon water reservoir in the bottom. There needs to be only one quarter inch hole about 3.5 inches from the bottom to allow for a water reservoir and air space under the device.
Some people choose to put a 5 gallon bucket inside a bigger pretty container, you will then take out the bottom drain plug of the container, so that when the water drains from the bucket it doesn’t stagnate within the outer container, but has a way to release and flow outside the decorative container.
Q. Can I use this in a plastic or resin planter?
A. You can basically use it in any container the GroBucket insert will seal against. We found several containers at the big home improvement stores that the insert fits. Remember, they cannot have a hole in the bottom, though, and you’ll need to be able to drill a drain hole in the side of the plastic container, so water may be released–You want the soil moist, not water-logged, so it needs to be able to be released from a drain hole. Smaller containers can be good for herbs, flowers, and smaller vegetables, but bigger plants like squash or tomatoes will do better in the bigger containers, like the 5 gallon bucket the GroBucket device has specifically been designed.
The good news: We have an added device currently “under construction” called GroBuddy, that’s coming out in a couple months, that will make grow bags and decorative containers self-watering. Follow us on social media to keep posted on its release date.
Q. Can I fertilize my plant with liquid fertilizer in the fill tube?
A. We dilute fish emulsion in water according to the bottle instructions, then apply to the top soil as well as pour into the fill tube. We feed our plants at least every two weeks and some plants, like tomatoes, every week. Again, we stress to make sure to dilute the plant food/fertilizer as directed and do not just dump it into the fill tube without knowing how much water is in the reservoir. Water evaporates and the solution may become too concentrated and harm your plant. If the leaves brown after you’ve fed your plants, you may have made the solution too strong.
Q. Can I purchase additional or upgraded water-level indicators?
A. YES, we now have our up-graded indicators available for sale on Amazon in either 3 or 10 packs. Search “GroBucket Water-Level Indicator/Funnel Kits” in Amazon.

The best way to dress up a bucket is to add a GroBucket garden system and some brightly blooming flowers
One of the biggest problems gardeners experience is under and over-watering. We've all done it. Life gets busy and before we realize, we look over and see a drooping deprived plant. "Oh, NO!!" What's a good gardener to do? Overcompensate, of course! We rush to the...
