Balcony Garden - cucumbers

Trying something new with cucumbers this year.  I planted them inside a tomato cage.  I saw examples of this on Pinterest so I figure it's worth trying.  (The water bottle has pinholes in it so when I water I can fill up the bottle and have it wet the soil slower - and hopefully longer so it won't be dry when I get home at night.  Also seen on Pinterest, I did about 1/3 my pots that way to see what happens. It's the one literish size before you tell me the pot is too small.)
