Plant the grow box with the desired seedlings. Space large-growing plants, such as tomatoes, about 8 inches apart and small-growing plants about 4 inches apart.
Drill holes about 1 inch apart throughout the surface of the lid using a 1/8-inch drill bit.

Building a self-watering grow box from a plastic container creates a low-cost container garden to enhance patios or small areas. The grow box is intended to be similar to the trademarked Earthbox and is designed to keep the soil evenly moist for an ideal growing environment. The supplies are available at hardware stores, and assembly takes about one hour. One benefit of this type of grow box is that the water reservoir at the bottom of the container limits the nutrient loss of standard containers that allow water to run out the bottom holes.
Insert the lid into the box so the bottoms of the pipes touch the bottom of the plastic container. Tape the edge of the lid to the sides of the plastic container using duct tape.
Cover the soil surface with a sheet of plastic. Cut holes that are about 2 inches larger than the seedling stems so the plants have room to grow. Tack the plastic sheet in place with garden stakes.
Measure the height of the plastic container. Using a saw, cut one section of PVC pipe so it is 1 inch longer than the container height. Cut three sections of PVC pipe to a length of 4 inches. Cut a “V” into the bottom end of the four pipes to allow free flow of water up the pipes and into the grow box.
Set the grow box where you want to use it before filling with soil. Fill the container with a well-draining potting soil. Mix water with the soil until it feels like a moist sponge.
Insert the long PVC pipe and one short pipe though the corner holes on one end of the lid so the bottoms stick out about 4 inches. Insert the other two shorter pipes through the corners on the other end so all four pipes are protruding the same amount. Verify that the “V” notches are on the bottom side of the lid.

The Grow Box is a great and economical system for growing vegetables.
After trying The Grow Box and Earthboxes, you may never grow a conventional tomato again. Self-watering containers, like The Grow Box, just make too much sense and work too well not to use for growing vegetables in containers. The Grow Box works really well and makes it easy to grow vegetables anywhere you have full sun.
The Grow Box comes with a fabric cover that has plastic tubes of fertilizer attached. These tubes supply a whole growing season worth of fertilizer, which makes growing vegetables successfully incredibly easy.
Setting up the The Grow Box for the first time is quick and easy, though the instructions are a little bit confusing and mine didn’t go together seamlessly – it took a bit of struggling to get the plastic flaps to stay where they were supposed to. Also, I must not have read the directions carefully because I didn’t keep the little pins that you break off when setting up. The Grow Box comes with everything you need except potting soil and plants.
Guide Review – The Grow Box is Great for Container Vegetable Gardening
The Bottom Line
Here are the downsides to The Grow Box by Garden Patch. Unfortunately, The Grow Box only comes with conventional fertilizer. Also, there is a big logo on the burlap box cover, though as the plants grow, it gets covered pretty quickly. Also, The Grow Box isn’t as sturdy as an Earthbox, which uses a similar system. However, for the same price, The Grow Box comes with fertilizer.
