Day 15 - Gave the girls 500ml of plain RO at 6.3(ish) PH. Watered in a ring around 'em to encourage the roots to spread out.
Day 16 - Didn't do anything today just monitoring grow environment Temp, RH, Leaf Temp, VPD etc.
Day 17 - Waterred 'em down again, 500ml plain RO at ~ 5.9 PH.
Days 18 &19 - Nothing done, just monitoring the grow environment Temp, RH, Leaf Temp, VPD, etc.
Day 20 - Waterred 'em down with around 700ml plain RO at ~ 6.1 PH.
Day 21 - Didn't do anything today just monitoring grow environment Temp, RH, Leaf Temp, VPD etc.
Notes:
I'm starting an Arduino project that automatically waters the plants based on the soil moisture and will calculate weekly water consumption. I already have one setup that does all of that and has a water level indicator that alerts me when the water level is low.
