Can you help me find the post on using PVC pipe for potting flowers?

?Sometime ago there was a suggestion from someone about doing a flowering pot with different lengths of PVC pipe . i know I would have to have holes large enough to plant the root or or bulb...but how would I keep the soil from falling out of the hole. Also this was very easy to take care of because you watered from the top and it all went downhill to supply each plant. DOES ANYBODY REMEMBER this. I wanted to use it on my patio.
