no you need you give them more than a spray bottle... , do you have them in small pots? if so, what i do to control the amount of water is i use a little mug with spout fill it up and gently pour to make sure it doesnt get too wet... you dont want to overwater but you still need to give it enough for it to keep growing. stick your finger in bout 1 cm in and make sure soil is moist but not TOO moist.. or it ll rot the seedling. hope this helps. peace
