I don't know what your room conditions (temp, humidity, fans, dome) but if they dry out everyday then I don't think you are watering them enough. What size cubes do you have? Are they in a dome? Heat mat? Room temps, humidity, fans, etc...?
i water them 2 - 3 times a day but not the rockwool, there the small ones, heat mat - no fan yes temps a little warm there in the garage thats my next delima where to put them in a few weeks when summer hits. dome yes dont know humidity. thanks
If they are the 1" rockwool starter cubes and you are watering them 2-3 times a day that is WAY to much. You should soak the cubes before putting in the clones and then let them almost completely dry out before watering again. Should be 3-5 days at least.Then after that you should only have to water the cube every 2-3 days and mist the leaves.
