hola ,how are you .you have all ready started just by thinking about it.
start small , maby a few herbs in teracota pots or a tomato plant stuffed in a hole in a grow bag.
but remember to go for stuff you like and dont get too dispondant the first time you forget to water and every thing shrivels up and dies on you.
i just lost an entire crop of babby lettices over waitangi weekend.
Cheers for this. I have just planted a few herbs actually and will see how they go but keen to get some lettuce growing this weekend
