Well im not concerned about them anchoring themselves anywhere. Im not growing outside this time of year or anytime in the future for that matter. Im positive they wont anchor themselves to a wooden shelf. I have 30" of total height, so im very restricted in the way i have to go about things for now until we move into a better house. My area is 30" high x 28" long and 20" deep. The only pots available were the clay terra cotta pots so i had to use them. They do have a big hole on the bottom and are a lil airflow under the drip tray. I didnt know they were that bad to use, but dont have an option at the moment. I can order different ones but that will take time. I can make some holes in the pots if getting air to the roots is needed. As far as temp, not sure how to cool it down. Its constantly around 80-85 in there. I have a fan in there but space is verrrrry limited.
