day10 the plant is still on the 1st node. I started to thing there is something not correct. Thanks to the great advice from @ORGANOMAN I noticed that the plant is drowning. The rockwool cubes are submerged 2-3cm deep into the bubbling water. This makes the tiny roots suffocating. Also the rockwool cubes can hold a lot of water. Also when I was looking the pictures form the previous days the leaves were pointing downwards.
I lowered the water few mm below the meshpots. Shook the rockwool cubes to release unnecessary water.
day11 plant leaves seems to start pointing a little bit upwards, hope soon the plant will be recovered.
Major update: I finally completed version 1. It's semi-automatic with carbon filer, ventilation, led timer and temp control. Sure will needs some updates.
Currently:
Water volume ~17l (~4.5G)
Air pump: HAILEA ACO-7703 10l/m
Carbon filer: Can Original 75m3. - f100
in-line fan, 107m3/h, 14W
intake dust filter
Digital timer
LED: KQO "quantum board ", very good v/p ratio. I am waiting a 2nd to be delivered. At 40~50 the panel literally doesn't need cooling. Max power for the box dimension 0.16m2 (~2 ft2) should be around ~90W. 45w per panel but double the area.
Driver 400W DC-DC boost
Old laptop power supply 20V, 90W
80W PTC heater, temp controlled
12V centrifugal fan
upgrades: higher power heater due to increased ventilation (basement ~12C(53F))
day12: with the additional ventilation air temp can't reach 22 and stays at ~17C. Water temp is even lower at 12C.
Tomorrow I will an aquarium heater. Hopefully it will help enough with the air temperature.
day13: added 100W aquarium heater set to 18C (65F)
I germinated 2 new seeds (Nefertiti and AK Mir (and 4 test seeds)) as current seems to be stunned. added 1ml/l Advanced Nutrition root simulator 35ml/cube.
Removed aluminum foil for better air exchange. I removed the rockwool cubes, squeezed the excess water and placed them back. There is 1 root per cube that is visible. American Pie 2nd seed seems to be sprouting.
day14: new rockwool cubes seems fine, only bottom is wet.
2nd american pie seed germinated
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.
