My lady is a Royal Queen Seeds Purple Queen. It sits in 9l of water with temp of 19°C. Water temp is maintained by using a copper tube within the reservoir connected to a peltier device with a water block. Lamp used is Viparspectra 450W led. All nutrition is from Vitalink. I have recently started using a homemade co2 generator made from yeast and sugar with water. I use Sonoff TH16s for automation incl water cooling and humidity control. The only problem I have ATM is that air temp goes too low but to 19°C at night.
