Both plants are looking good. The 1st germinated one is still very, very small but the 2nd pair of leaves are already growing.
The 2nd germinated one has normal size , could be a little bit bigger, but it's ok so. All is green.
I'm watering a little bit every 2nd day and give root-juice from Biobizz. Today i gave 1st time plant spray from Green-Buzz-Liquids. I give the spray after the light switches off for night.
2 days ago i switched the led from grow light to full spectrum- light. Distance is approx. 20 cm.
Temperature during light is 30 degrees, during light-off is 20 degrees.
All is looking good :-)
========================
Update - 26- Aug - day 20
Both plants are pretty green. The small one is very small for 3 weeks, but she's growing. The big one has 1 leaf curling up a little bit, could be that it's heat stress. Increased the distance of light with 5 cm more. Heat during daylight is 30-32 degrees. Will take care now, that 30 degreed will not be exceeded in the future.
