Hi, Okay i will be starting up a grow soon and will be using small rockwool cubes to start my grow in. Im wondering how much do i water the little cubes. And once i move them into the bigger rockwool cubes do i water them more then or keep the same watering cycle
The little cubes are like these \/ and the bigger ones are the same just bigger

Any help at all is very much appreciated

Thank you

just dip like 1/4 or half of the bottom of the rockwool cube in water.. dont water on top.. so you can let roots grow down and to look for water.

when they root you can put them in soil... u dont need bigger rockwool. use good soil! :) foxfarm is great! pH ur water (6.2-7.0) very important. Goodluck! keep us updated

rock will will hold water incredibly long with maximum amount of airation. soak the rockwool cubes in a ph water of whatever you'll be watering your ladies with, as the rockwool has a high ph when opened. i watered my sprouts in rockwool cubes once every other day, when they are lighter. pour water over them get them wet and feel their weight, when they lose a little weight, time to rewater
