You should add 550mL water to your micropod when you set it up for the first time. If you don't have a measuring cup, then make sure you fill the water to the top indentation on the inside of the tray (see image below for reference). The seedmats should be almost floating in the water and the water will absorb into the mats.During the more mild seasons, you should only have to add water once, but when its hotter/dryer, the mats can sometimes run dry and some seeds may not have enough time to properly germinate and establish a root system. We recommend adding a little bit more water at the start during those hot summer months.
