The plant on the bottom right is way ahead of the other 3. Probably because its next to the air intake and directly gets the dry air from outside.
I tried everything to lower the humidity but its still 60% (22°C) with lights on and close to 70% (17°C) with lights off.
Bit the bullet and ordered an 10L/day 200W dehumidifier.
It keeps the temperature at 24°C and RH at 40-50 %. Could still turn the settings up if i need more.
The Power consumption of the growbox is now at around 0,3-0,4 kwh.
@Insane42069, Danke, dir auch!
Mal schauen was dabei rauskommt, die Ladys sind noch zu klein... Eine fängt bald schon an zu blühen.
Meine nächsten werden auf jeden Fall keine Autos mehr.
