So my plants are at day 6 from sprout and today I opened the cabinet and to my suprise one of them fell down, it's like she was too heavy and just couldn't stand up. The top of the plant adjusted to the light. I got a toothpick and stick it in the soil with a rubberband to hold the plant, the stem looked a little bit yellow and the top of the plant is pointing to the side.
Any idea on why this happened?
I see you are online Chup.
Good discussion. Most of us have seedlings falling from time to time.
At just a few days old it is likely to be rooting and stem stability. The seedling pushes itself up and roots are just starting to head down. Most of us--do what you have done and add a little medium around the base for extra support.
They are very hardy even when young. And do whatever it takes to survive. They will surprise you.
Cheers
