Lunch time is not enough to take care of all these things. You better check their opening time and see where is the best place to submit your application.
By the way, where do you live? Do you think joint venture for farming works?
At the beginning when there has no plants, that may be OK. But once your seeds grow better then you have to fix the net, the fence, the worm, the bird......... I think one hour is not quite enough even if you go everyday unless your plants are not growing.
