miss b,as long as condensation is forming on lid and upper sides it should b ok,u dont want to much wettness,just need enough to give up to 100 percent humidity,if the eggs start to dent usually meand a bit dry,but if they swell to wet,its a fine line,lol,when i mix water and vermiculite,i add extra water then squeeze it out,never done the weighing of each,and hatch ridgeys,beardys and water dragons with no issues,so there is a bit of lee way each way,when u add water,do it away from the eggs around the edges and little amounts at a time,and wait a day to see if that helps
