First time growing in DWC. I ran a test grow with spare seed. The grow is fine with just few minor issues that seems to be fixed. Still dialing up the system.
Custom wooden grow box 90h 50w 35d cm. (~2ft2, 3ft height)
Led light is quantum board with lm281b+ rated at 120w. As per the recommendation of max~ 60W per ft2 I will use reduced power.
Germination
day 0 - seeds at wet paper towel
day 2 - American Pie germinated
day 3 - AK Mir germinated
day 4 - Nefertiti germinate, all good, moving to rockwool cubes
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.
