Pro tip: I started using old plastic bottles as mini greenhouses for my seedlings

My balcony gets really windy in the spring, and my tomato seedlings kept getting knocked over or drying out. I cut the bottoms off some 2-liter soda bottles and placed them over the small pots. It only took about 4 days to see a real difference, the plants looked stronger and the soil stayed moist. I leave the caps off for air and take the bottles off once the plants touch the top. Has anyone else tried something like this for wind protection?
