Terrarium As Mini-Greenhouse

So, I found this terrarium at Walmart and instantly had the idea to try to simulate a large scale glass greenhouse. 

I figured it would be the closest to a high end version I could afford for now. I even thought it would be a good way to reverse engineer my own copy. As you can see, I am going ahead with staring a few Jalapeño peppers and cucumbers in this. But one more thing I also wanted to do is keep watering from the bottom as I have done with most of my starts, seedlings, and plants to much success.

But, alas, I soon realized that the terrarium is not water tight. Perhaps this is a good thing when it comes to its original use; as being able to evacuate excess water would be desirable. 

However, for my purposes, it's not ideal. I will try lining the bottom with aluminum foil to see if it will hold a water tight base. 

There's so much to like about this that I'd hate to call it a bust!
