Second try at growing, 2x Green Crack

Madmick88 I'm back, had to destroy my last grow due to unforeseen circumstances. Another go at this game. I overwatered my last grow, trying not to do the same with this one. These two broke soil at day 6 after planting which is today. which is understandable as first 4 or 5 days of that were spent outdoors and they didn't get much light. Green Crack #2 is 1.5cms long and Green Crack #1 is at 2.5cms as of now. I have watered 3 times, 1 liter each pot each time. First during plantation, once after 4 days and once today because the pots felt extremely light and dry.
