Plants are growing quickly at this stage…here they are three days later than the photo above. The largest Zkittz plant is growing her 5th node. I will be topping after 6 nodes are formed. I think the plant is showing some minimal lighting stress, so I’m watching them closely under the higher intensity lighting.
I am always afraid to fry the plants under the LEDs, so I’m trying to ease them into the higher intensity lights. Using the free Photone lighting application, I’m able to determine that a 3 week old plant should be getting a 30 or less Daily Light Integral (DLI). DLI is calculated based on number of hours of light (20 hrs) and lighting intensity (366 ppfd). So….my DLI is 25.7, which is below the max of 30 DLI. Soooooo…….i will let the plants acclimate to the higher light and slowly work up to 30 this week. For anyone that measures their lighting in lux, this is close to 20,000 lux.
I no longer need to run a heater in the tent. The LED is generating enough heat to hold the tent at 78 degrees. The humidifier is set to run if the VPD exceeds 1.0 since humidity lowers the VPD….so tent conditions are ideal currently.
Next update this week when I install the UV/IR lighting in the tent and start using InfraRed lighting to encourage stretch.
