Carl_Lauberbach Plants are watered once a day with plain tap water.
The lamp was set to the lowest setting for the first five days.
For the first day, the lowest setting is fine. After that, the intensity should be increased to ~45% to prevent stretching.
Humidity is set to 70% RH.
The plants will be transplanted into larger pots, since the roots are starting to emerge from the pellets.
After transplanting, humidity will be decreased to ~60% RH.

Carl_Lauberbach Plants are watered daily with a minimum of 10% runoff.
After transplanting, the plants initially received a low fertilizer dose; the base fertilizer and CalMag were ramped up over three days until the target level was reached. Fertilizers are dosed according to the Canna feeding schedule.
Temperature is maintained at 23 °C using a heater.
After one plant was exposed to the humidifier’s mist stream, it began to droop. The mist stream was adjusted, and RH is now set to 60–65%.

Carl_Lauberbach Plants were topped on 13.02.26 and transplanted on 16.02.26.
The light in the small box seemed too intense after topping, which resulted in slight yellowing and drooping leaves. Reducing the light to around 16,000 lux led to recovery
Plants are now fertigated four times a day via an automated system: the first event occurs when the lights turn on, and the last event occurs when the lights turn off.
The AC controller (AI) is set to maintain the target parameters (26 °C / 60% RH during the day and 22 °C / 58% RH at night).
The water tank will be cleaned and refilled every sixth day. A cloth is wrapped around the tank for insulation. The solution is cooled via a metal spiral connected to a cooling system.
A second container is used to collect runoff. Runoff will be around 10–20%.
Moisture in the pots is measured using a probe.
Fertilizer is dosed according to the fertigation plan from canna.
Concentrations might be reduced regarding the runoff EC.
