A Grow Bed is the most efficient garden area you'll ever tend, with black plastic sides that absorb heat to warm soil early in the season, then help retain moisture all summer long. These two-sided extension kits double the growing space of our popular grow beds by creating a raised bed that is the same width but twice as long.

Works Okay

The metal rod that keeps the unit from falling out is a little small - the sides bow in instead of out. However, it seems to be holding up.

Extend size of garden

Purchased smaller bed initially. Extender allows me to double my space to grow more.

Great After Assembly

3

I am replacing some wood planters that have rotted - have had good results with the basic square kit. This is the first time I've used the extension kit and it was a bear to put together if you follow the directions. I found it easier to lay the two sides out flat, drill the holes and screw together. Then move those sides out to the garden and pop in the end pieces.

This one I just could not get put together properly.

I own 2 of them.

It would be much easier to assemble if the directions were rewritten. I knew how to do it when I finished. The directions were a hinderance rather than a help.

Just the right size.

My husband and I created a bed for asparagus near a current flower bed to make watering easier. The bed is just the right size.

Sent with pieces missing

was fairly easy to assemble once the missing pieces arrived.

Difficult to drill holes in the heavy plastic

3

I bought this to match a grow bed I purchased a few years ago. I like the quality of the grow bed overall but it is frustrating to have to measure and drill holes in the heavy plastic. Assembly requires two people due to the need to measure/mark holes and hold pieces steady.

Great extenstion bed

5

I was very pleased with the larger grow bed so I decided to give myself a little more growing space and added the extentsion bed. I am very pleased with this product.

A little clunky

3

The awkward way to attach two three by there beds together and the difficulty of moving the assembled bed around made me wish I just bought 2 more 3x3 beds. Mine price savings made me pick the 3x6 but the 3x3's are much easier to assemble and much more stable.
