bullet planter  

drill away
Thats exactly what you do! Drill on.

NO
This is to conceal a pot, not the pot itself...

yes
drill away,its not worth anything! make it useful,drill,drill,drill.

I'm with
A. Chicken. No drill = no cracks + vintage preservation. But, what do *I* know. . .!

Don't Do It
Whatever you do, don't put a bloody hole in it!!!

Next sombody's going to tell you to turn it into an up-light or an aquarium.

DRILL DRILL DRILL....
OR -how to turn a 125.00-150.00 item into a 15.00-20.00 item.The old bullets in good condition(no holes) sell for that esp in the colors gray or red fiberglas...

sorry
i can see that i have upset a few people here with my idea of drilling holes in a totally useless object just to turn it into something horrendous like...useful?.. drill on babe!

CACHE POT 101:
In 18th century France cache pots were in common usage,as they are in many cultures now and then, its NOT a hard idea to grasp.This is the makers and designers intent in THIS case, that is why there is NO HOLE.This is to conceal the utilitarian pottery,to catch slight drips of water,etc.Ideally you should lift out the potted plant and water it ouside.

When this
query was first posted, I shared it with those on another design site. Today, two responses appeared.

bullet planter
thanks all. I kinda had the feeling that these are for putting a pot inside, and so the lack of drain hole. One further question, can these be put outside in warm weather?

.
Certainly they can. Only a freezing and expanding plug of ice might cause them harm. . .
The steel-rod base would want to be inspected for rust, after a season of rain.

Just
had one more response to the question, on another forum:
"For what it's worth - I have had three bullet planters for almost twenty years, and the plants in them have been there for almost that long. For drainage, I just put about 4" of gravel in the bottom, so that water collects down there, and (presumably) evaporates. Never had any trouble with them - and I am not a plant person. Every other non-bullet planter plant I've ever tried to grow has died on me."

Gravel the way to go
The gravel technique has the great advantage in dry, heated homes of raising humidity in the immediate vicinity of the plant.
