The Growums grow box looks similar to Earth Box and Grow Box designs, with a few differences. The box has 2 tubes: one to fill the container, and the other one to show the water level via a floating indicator. The box is closed with a rubber plug and there is no significant danger of overflow, which is not the case with Earth Box (overflowing is a sign of a full Earth Box).
I asked a the company a few questions about their product. Here are the answers I received from the VP for Products in December 2012:
"1. Are the boxes made of food grade plastic? NO
2. There is no number at the bottom of the box. BPA-free plastic usually has a number 1, 2, or 5. They are #5, polypropylene.
3. Are the boxes UV-stabilized? Yes
4. Are the white watering pipes made of PVC? No. Polypropylene
The instructions on the Growums site (www.growums.com) will give you more details in the future. Good luck in your gardening efforts. Again, you can always go to our adult gardening website - www.learn2grow.com - for more information about the plants you are growing, articles, recipes and our huge plant database."
The company is heavily focused on marketing to children. The box was available discounted to $9 at Lowe's in September-December 2012.
Here is a video how to setup the grow box from the popular YouTube channel Growing Your Greens: Discounted $10 "Earth Box Clone" during off-season - Growums Container Vegetable Garden at Lowes. John ads other ingredients to the coconut coir provided with the mix: vermiculite, compost, worm castings, Azomite. I added vermiculite, compost, worm castings, and organic fertilizer.
The company that makes the Growums boxes made a video showing how to use them:
Here is another video from the company:
You can make your own potting mix:
