How should I water girls this age - 8 days?

When they that size I do like 10-20 squirts with a hand sprayer per day and they seem to like it. Try to get the top 1-2 cm moist and then it should dry within 24 hours and then do that each day until the have 2-3 pairs of leafs and they will he able to take more water on

Slowly 😁

Hallo when they are that young you can lightly spray some water closely around the new seedlings. And then a couple days in slowly spray more away from the seedlings. So the Roots start in middle and spread out gradually to the side of the pot . Hopefully this helps happy growings mate 🤘🏻🤘🏻
