Giving My Container Garden More Sunlight

On May 7, I took all the small containers and put them on TV trays to allow them to get more sunlight. The balcony bars create areas of shade on the balcony floor that I thought might have a negative effect on plant growth. Raising the plants hasn't helped so far. Of course, it's also been totally gray and overcast for all or almost all of the last ten days, with the exception of a mere two days.

Conclusion: In the end, I don't think this strategy helped, but I think it failed because of a very overcast spring more than anything else. Except for one thing: the tables underneath the plants became extremely moldy because of my genius idea to put towels between the plants and the mold. That can't have been good for my plants. I wonder if this could have been the cause of the infections that ultimately destroyed my tomato plants.
