Garden Patch Grow Box vs EarthBox
EarthBox Garden Kit
The EarthBox Organic Garden Kit (Buy Online) is one of the most popular garden growing boxes on the market. This self-watering planter takes the guesswork out of gardening, so you can reap a bountiful harvest even if you don’t have a green thumb.
Container Size – Water Reservoir
The EarthBox Garden Kit comes with a 2-cubic foot container and an aeration screen that separates the water reservoir from the soil. The water reservoir in the EarthBox can hold up to 3-Gallons of water, while the Garden Patch Grow Box can hold 4-Gallons of water
The fill tube that comes with the EarthBox Garden Kit allows you to easily fill the water reservoir. However, the fill tube needs to be passed through the soil when you fill the planter. While the GrowBox (Buy Online) can be topped off with water using a convenient filling port located on the side of the planter.
Portability
The EarthBox Garden comes with 4 caster wheels that will make it easy to move the planter even when it’s filled with water and soil.
The GrowBox, on the other hand, does not come with wheels, so it isn’t that easy to move, especially given the fact that it will weigh 50 pounds when it’s filled with potting mix and water.
Mulch
The EarthBox Garden Kit also includes two black & white plastic mulch covers. The black side will help warm the soil in the spring, while the white side will keep the soil cool and moist in the hot summer sun.
The Garden Patch GrowBox comes with a permeable Nutrient Patch that releases fertilizer, stops weeds, and you can cut holes in it with a knife based on the instructions in the plant spacing guide, which makes it easy to space plants of any shape or size.
Fertilizer
With the EarthBox Garden Kit, you also get 1-pound of 7-7-7 NPK fertilizer, along with a 1-pound bag of dolomite lime. The GrowBox comes with a bag of time-released fertilizer, but it doesn’t include any dolomite.

EarthBox Staking System
The EarthBox Staking System (Buy Online) helps support large plants like tomatoes or vines. The Staking System uses a net as the primary support structure. That makes it suitable for most plants, but it might have trouble supporting melons or other heavy fruit-bearing vines.
The EarthBox Staking System is 60-inches tall and it’s easy to assemble and install on any Standard EarthBox.
It also comes with outriggers that make the whole system more stable and less prone to falling over. You also get 2 casters that can be inserted into the outriggers, so you can use it in conjunction with the casters that come with the EarthBox Standard Kit.
GrowBox Support Cage
The GrowBox Support Cage is made of fiberglass and it has a faux bamboo design. It’s made to be used over any kind of planter, so you could even use on an EarthBox or a City Pickers self-watering planter.
The GrowBox Support Cage uses thick rods that can hold up more weight than netting, so you can use it with heavier plants that need more support. The whole structure also collapses down for easy storage.
There are also no metal parts on the GrowBox Support cage, so you won’t have to worry about it rusting or weakening over time.
EarthBox Mulch Kit, Black/White
The EarthBox Mulch Kit (Buy Online) is a plastic mulch alternative that helps prevent weeds, and it keeps the soil at the proper temperature and moisture level all season long.
