Stand 'n Plant 

I just ordered one special and he added 6 inches for me, because I too am tall. It's like ten extra bucks, that's it.

You can add a section of pvc to the top. to get it to fit, warm the pvc and push it into the top of the funnel. make it the height you want it. look up making pvc fittings on the Ytube. It will look like a fishing pole holder. Use a bottle to flare out the warm pvc opening on top

I agree. It's like the world is made for the average 5'9" person. I'm researching planter right now. Going to order one today from someone.
