Hi there Guinnessman i'm having the same problems. No garden only concrete.
There's a type of tomato you can grow inside or outside in containers its called 'Tomato Money Maker'
Here's the list im attempting to grow.
Outside small plastic mini greeenhouse thing in growbags:-
Cucumbers
Peppers
Aubergine
Tomato
Containers (Long straight)
Leeks, Carrot, and Sugar peas
Runner beans and peas.
Old plastic milk bottle tubs:
Mixed salad leaves
Spinach and Lettuce
My method worked last year with carrots and salad stuff so im being a bit more adventures this year. Just remember to make sure the bottom of the tub has holes in it or it turns to stinky goop!!!! :oops:
