I been reading alot about when to transfer and to be honest i still can't figure it out i had these girls in rockwool for about a week now maybe 8 days i seen small root poking out the rw on the bottom and i thought it would be best to put it in pebbles so it can moving down and trying to reach the water. I am watering my plants everyday with 175 ppm ro water. I seen growth everyday but i felt like the root had no where to go anymore because it was standing on a dome. Did i do the right thing here ? I know they are still very young.
