I don't measure the exact amount of water I am giving to them at that early stage but it is equivalent to 10 ml each time I water so I water less but more often . You can start in a solo cup and then place it into you final pot after a full germination, the only negative part of that method will be to (maybe) loose some time because of that transplant ( from the solo cup to the final pot ) 😊✌️🏼
