Sandman... there may be a problem on the horizon for you..
I don't see eye to eye with Zandor on this one... LOL

Your plants actually need water about once every day or 2 days or 3 days... ,maybe even every 4 days if they are sitting in wet rockwool cubes... it all depends on how fast the rockwool cubes dry... I can not imagine rockwool ever needing watering every 15 minutes...

Now.. you are waterinjg your rockwool from the top... some people who water the cubes from the bottom can water more often..

the roots must have o2... and as great as rockwool is, if it is saturated it will smother your roots..


The basket should not be heavy and dripping all the time... please keep us posted...
