Thank you @delishtreats, I am so excited for my harvest!! This is the most I have ever planted at one time, I am a relatively new gardener.
I had been thinking about planting potatoes in the box, great minds!! I too am a potato lover but so far they haven't grown too well in my garden, the box could change everything though! Here in Spain it will soon be summer so it could be a bit hot and dry to start them now, I'm sure could try in a couple of months time once the worst of the heat is over :)
