This is a turkey baster and I use it to water all my indoor plants. It only plunges 110 ml at a time and is perfect for giving small plants water. I notice you have plenty of small container plants and using this baster will help to measure and not over or under water. I use it to water big plants too, I pre-measure water in a 1000 ml measure cup.
NOW, what make this so wonderful is I aerate my water by plunging air in the cup first before giving water. That way the water is full of oxygen before each plant gets water. The photo below is showing how I add oxygen to the rain water before using it, just a couple of plunges of air into the water and its loaded with extra oxygen. Try it you'll see what i mean its amazing.
