when will my seeds be ready to go in the system after germination?

hey was just wondering if my seeds will be ready for the system right after germination, or should i let them root in the rockwoll a bit first

Once they root out the bottom of the rockwool they should be ready to go.

alright. how low should i let the rez get before I refill it to the net pots bro? ive got the basics down I just like to be sure

just throwing it in a starter kit before the buckets. 4 gallon tub

Small plants wont deplete your water supply if you are in any decent size container. Your water level will be the same for a few weeks for sure, when they do start drinking I like to keep mine at bottom or slightly below bottom, I refill when I notice they are down from where I want it to be. Usually every two three days or so when they are teenage plants.

nice thanks. is there a specific way you germ your seeds in the RW before put in the system.
