      I bought the extender for my father who had purchased the 3x6 frame for his small backyard garden (tomatoes, peppers and squash mainly). He is really pleased with the extender and said that his garden is just the right size now.

      Comments about Grow Bed Extension Kits:

      I've had 3 Grow Beds with nets for several years. Since the kids don't play as much in the backyard, I decided to expand the vegetable garden this year. The extension kits seemed a smart way to do that.

      They were easy to install and the metal braces add extra stability. I would have given them 5 stars except that I think that they are too expensive. A home organic garden shouldn't break the bank.

        Best Uses

          Comments about Grow Bed Extension Kits:

          This product has been a big waste of time. It arrived without assembly screws, so I called Customer Service and they sent separately. Then i had to find an electric drill (question - why don't they just predrill the 8 holes at the factory? It would take them probably 10 seconds). Once i had a drill, I discovered that i was also missing the Corner Pins! So called customer service AGAIN and they said would send. So, still waiting to assemble.

            Love the mini grow bed and extender. Put on my slope which didn't allow for a lot of depth but I could go wider so this was perfect solution! Looks great!

            Comments about Grow Bed Extension Kits:

            I have been growing backyard vegetables in the 3' x 3' Grow Bed for several years. I wanted to expand my growing space and the Grow Bed Extension Kit was just perfect. The only drawback to the plastic sides is that over time they bend a bit from the weight of the soil (mine sits on a slight incline). I had a hard time drilling holes for the connecting plates, but it was manageable. It's still a great value for the price.

              This is my third purchase. They are perfect for my small inner city house. They snap together very quickly. If you buy the extenders you do need a drill - since you have drill 4 holes. Not having one I traded some future vegetables with a neighbor. If I had more yard I'd buy more beds.

                I have a big city pocket yard and these are perfect for making the best use of what little yard I have. The only con is that an electric drill is required to attach the extensions. I had to barter with a friend who has a drill to get it put together.
