can you stack one on the top to make it higher

The finish on top and bottom rails are flush. In theory, you can pre-drill holes and use threaded bolts and nuts to connect one on top of the other, but that won't give you the lateral rigidity as a single unit.

Not unless you make new poles that go on each side because the pole that are provided are only as high as the 3 sections would be.

Yes! I have two and they are extremely easy to stack vertically, you just pop in the bottom feet of one into the other. They're also really sturdy and feel well-made.

I don't see any reason why you wouldn't be able to stack another set on top. All 3 levels are interchangeable, the "feet" are the same.

No, There is no way to put them together. The directions clearly state to not stack them. I believe they would be very unstable.

Yes mechanically they could be added together but it would need a stabilizer for the height.why would you want it that high??

I have not tried it, but I don't see why not. I don't think they will fit together very well though and the top one might slide off if bumped.

Stacking is physically possible, but the result would be very unsteady. They were not manufactured to enable stacking.

Yes you can. I bought one and it came with a wall bracket and 2 pegs to place in the top to add another above.

No, not really. The only way to stack them is if you turn one upside-down on top of another.

They can be stacked. I have never gone over 2 of them stacked though. Hope this helps.

Not designed to be stacked but with some creativity and extra hardware you might be able to stack them.

I dont think you want to stack them. You should order one that tall. They have them.

Yes you can!! We have stacked them 2 high (2 big squares) but it would be easy to add another . 2 high was just fine for the tomatoes. But I will warn you that the tomatoes do get very tall but it is nice to just reach in with very little bending.

This item is not made to be stacked. Take note of the way it is made on the bottom, it would not be stable enough to be placed on top of another. If you are creative however, you may be able to place something in between or attach them in some fashion to one another to make it more stable. I hope this helps.

They are not designed to stack on top of each other, i.e. there is no lip. But I suppose you could stack them on top of each a few high, before they become unstable. :-)

I don't think these are really made to stack. You might could but I don't know how good it would work. I only have one so I don't have any way to test that.

Somewhat. They dont fit all the way down, but I do stack mine...but only a couple at a time. I think all of them together would make them topple over.
