I just bought a superflower led 3.0 and was wondering when you are top feeding, if the clones are in rock wool how often do you have to water them, because I am on my first grow and right now the water is set to 15 minutes every 6 hours, i don't want to over water. anyone help with this? here is a couple pictures. outside inside inside top first set of 8
you can't over water hydro? i didn't know that i thought with the rockwool holding so much water you could but since i have changed the feeding to 15 min every 3 hours. but i made a new post because now it seems i'm having a diferent issue.
I think the above post is correct. As long as you have some kind of constant oxygenation, you can't really over-water the plants. In a DWC system, the roots are CONSTANTLY under water, but those plants thrive because the root zone has enough air, so I feel like the same conclusion can be had about rockwool; as long as the water is oxygenated, you can't really overwater.
here is a link to the different post i made it has more pictures and my setup. http://forum.grasscity.com/absolute-beginners/1280995-need-some-help.html#entry19481850
