I've actually considered having a indoor garden geared more towards veggies with a couple special herbs in there. Most of my gardening knowledge is from pot growing sites... well mainly this one... but I apply the principles to my veggie garden-nutes,watering,topping,pruning,lst- and most people say I have the best garden they have seen. For the most part plants are plants and grow within the same parameter spectrums- now if you want to grow odd crops- cold weather/desert/etc- there will be issues but otherwise stack up any unused space- it's just light your paying for going to waste.
