Rock wool dampness
i'm with sensisuperskunk here. i learned that first hand that rock wool can become overly saturated and then can cause ROOT rot if it is saturated for too long. first hand knowledge there. learned the hard way. my opinion is do not let rock wool sit in water or not water every day. it will take an easy three days at least before the rock wool comes to a dangerous dry state.

I only spray my seedlings when I spray the humidity dome. Also, I have had rockwool dry out in a day or less in high humidity conditions. So, the three days thing isn't probably the best rule. All a matter of opinion I guess...

Of course you don't let it sit in water,anything pourass can become over saturated, but if you use a flood and drain system and soak for 15-30 minutes per watering, there is NO way to over water with rockwool

Rock wool dampness
One last thing I have grown strickly in rockwool for years and have a flood and drain setup, I water 3-4 times a dy and NEVER have had any root rot problems. I have tried everything from lava rock to river rock, to perlite,and clay pebbles, nothing works as well for me then rockwool. The only drawback is the cost since I always use fresh rokwool for each grow.
