Welcome to AFN and the New Growers forum. Looks like your plants are off to a good start. I'm curious about the rest of your setup. What kind of soil and nutrients are you using? Also, what is the temperature inside your grow box? Regarding watering, you don't need to be doing it daily. When you water, give enough so that about 10% of what you give runs out the bottom of the pot. Then wait till the pot feels very light, then water again. With a small plant, this may only be every 4-8 days. As the plant grows you will need to water more often. What kind of water are you using?
