Answer: Good question! I'm not familiar with the see-through planter, but it stands to reason that without good drainage, the roots will suffocate. There are two possibilities: there is a false bottom so excess water drains from the soil, or there is a layer of rocks and/or charcoal on the bottom where water can collect, but the roots can stay high and dry. I'll do a little more investigating, and you should, too. Be sure to examine the planter thoroughly so you know how to treat your plants.
Best wishes with your endeavor!
