If the breeze is blowing across the soil or through the air holes, it definetly will make it dry quicker, I would think. But I doubt thats the problem, just means you would need to water more often.
If the plants look healthy and they both are the same size, I wouldn't worry too much yet. Get some pics up if you can. Your last run on the balcony, they may have just stretched more due to lack of light and appeared to be "bigger". You may just have more compact plants which is something I noticed when I made the move from outdoor to indoor. My outdoor plants just weren't getting enought hours of light and stretched quite a bit.
You could PM any of them. They should at least be able to get your request to the right person. Namvet is usually online.
