Euforia. High frequency fertigation

Carl_Lauberbach Euforia cuttings obtained from Hanfgarten were received on 20.11.2025 and immediately transplanted into biodegradable pots filled with coco substrate. The plants are irrigated once daily, ensuring at least 10 % runoff. To achieve a calcium-to-magnesium ratio of 3:1, 0.4 mL of Mg Mono (Canna) is added per liter of tap water. Subsequently, CalMag Agent is added until an electrical conductivity (EC) of 650 µS/cm is reached. The plants are fertigated according to the fertigation calculator from Canna. In the first week, the plants receive a light fertigation dose; after that, they receive the normal amount.

Carl_Lauberbach The plants were drooping for the first few days, but they seem to be recovering now. Recommendations for the next run: The base of the plant should be buried slightly below the surface, and coco should be reapplied after watering to ensure it still covers the plant’s roots. For the first three days, the water should be adjusted only with 0.4 mL Mg Mono and not with CalMag. The latter can then be increased in 2–3 steps so that the electrical conductivity reaches 650 µS/cm. The lamp should be set to 25% and the humidifier to 55%.

Carl_Lauberbach The plants were topped on December 1st. The plants were transplanted on 04.12.2025. For transplantation, the biodegradable pots were sprayed with water before removal, as the wet material can be detached easily without causing significant damage to the roots. The plants were then placed into the grow tent and watered to runoff using the irrigation system. The plants are fertigated according to the light supplementation plan. The plan will be switched from light to normal nutrient supplementation on 07.12.25. Initially, the pump runs five times per day for 2 minutes, except for the first cycle, where the pump is active for 10 minutes just before the lights are switched on. The radiator in the room is switched off for the following days because some flowers are being dried in the room. The heater, humidifier, and exhaust fan are regulated via the AC Infinity Controller (AI) to maintain 23 °C and 58 % RH during the day, and 22 °C and 58 % RH during the night. The lights are dimmed to the lowest setting. After the other plants are dried, the radiator will be turned on and the target will be set to 26 °C / 60 % RH during the day and 22 °C / 58 % RH during the night.

Carl_Lauberbach The photoperiod was switched on Devember 11th, 2025. At this point, the plants had reached a height of 30 cm. The plants are now being watered five times per day, with an initial irrigation pulse of 10 minutes. The following four events occur at 2.5-hour intervals, each with a pulse duration of 5 minutes.
