I decided to make a planter box out of a cable spool and here's how I did it.
First I started with a plain medium size cable spool
Then I stained it a dark brown.
After I stained the whole spool I cut out 1 of the boards using a saw zall.
The best place to cut the board is right above the hole between the 2 nuts
Then I filled 2 one gallon milk jugs with water.
Placed the gallons into the spool
I made my planter boxes to sit inside the spool and I put 2 cotton wicks that I made from ripping up an old tee shirt.
I made an X in the milk caps and fed the end of the cotton wicks into it then I put the wick inside the milk jug
I set the planter box in the spool now if it doesn't rain for a while the planter box will get it's water from the milk jugs underneath thanks to the wicks all I have to do is lift up the planter and check the jugs every once and a while.
