I have used Earth Boxes for several years...currently I am using them to grow 30 types of tomatoes. I also have one with telegraph cucumbers, and a couple of others with bush beans. I used to do peppers in them, as well; but switched to Smart Pots this year. No reason...just for the hell of it. The key to an Earth Box is FOLLOW THE INSTRUCTIONS. I still have my originals, and will be buying more next year if I can get more land.
Looks like I pulled the trigger a little early - I just could never follow the ROE very well! LOL
Do you reuse the potting mix or just renew it every year?
