Love your sign-on name. You should have seen me in the 80's! Big, big hair. Ahh, the memories.
Anyway, some things to think about re your rental perming up. Think about using lots of deep polystyrene trays (with holes), all pressed together. They insulate the soil really well, and you don't get all the gaps you get with round pots. They fit anywhere too. Use lots of height with trellises for climbing plants, and shelving. Have a look at some of the verticle garden products around. Benefits are that you use space so incredibly well, and really reduce water waste, as runoff from above waters the plants below.
There are also some great designs using polypipe and pots with wicks in them to draw moisture up. Just a trip to the hardware and a bit of time, and you've got a great way to grow stuff with such little water, and no water waste.
Make sure you keep a worm farm or one of those nice indoor compost buckets to generate enough fertiliser for your endeavours, and try to keep some bowls or fish tanks of water to add enough to your system to attrack beneficial insects. This will reduce the amount of pest control you will need.
All the very best, and enjoy your food!
