First Auto DWC grow -> outdoor

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
