This maze idea won't work unless the plants can at least SENSE the sunlight. (Plant's growth towards the sun is called phototropism, and is caused by plant hormones called auxins). Unless the plants at least SENSE light, there's no way it could grow towards that. For example, you can't put a plant in a dark closet and expect it to grow towards your lamp that's outside the closet.
