Lately, I've seen many setups that are leaving rockwool exposed in the late germination and beginning stages of vegetative growth. In some cases, the rockwool is simply resting in a grow tray, and the lights are above it. The cubes are transplanted when the roots show signs of popping through the sides.
My questions are:
How do you avoid algae buildup, mold, and such problems by leaving it exposed?
Would H202 help in concentrated doses in the water solution until the cubes are planted a week or so later?
The reason I ask this is recently, my plants were all put to rest. After battling for a while, I discovered root rot to be the cause of all the other problems. In my 10 day long absence, my reservoir and overflow worked to perfection, but the rockwool was slightly exposed to light. The flooding caused it to get very wet, and with light on it, the problem started and manifested rather quickly.
