Today is day 10 after seeds showed from rockwools. pH i 5.9, ppm is 200. Seems very slow growing or maybe I am too anxious.
Water level is ~2-3sm above the netpot bottom
Does it seems fine?
Thanks ORGANOMAN for the great advice.
I firstly removed the cover. It's in a colder place, so temps are ~20-22C (68-72F)
Seems that water is suffocating the roots as they are the rockwool cubes are submerged 2-3cm. I lowered the water just below the meshpots and waited for some water to drip from the rockwool cubes.
I will wait for 1-2 day for an update.
