Hi,
it seems your special plant needs more light, the plant is very stretched. If it continuous to grow like this you’ll end up with a really weak plant at the end. Do you have any plant-lamps or bulbs that would give it more light.
What is the temperature range?
Experimental plant pods contain food upto 4 months, but you should probably transplant it earliet due to rootbound. And if you replant- plant it a little deeper than it is today.
They look like they need more light. I took foam boards but even cardboard would work and aluminum foil to cover one side and placed around 3 sides of the unit to reflect light back last winter and that really helped. Then wait a little bit longer so they get stronger before transplanting.
If it’s an autoflower, I usually transplant mine after 3 weeks, and grow them outdoors in full summer sun. After circa. 3 weeks, the roots start curling around in the pod, and the transplanted plant does not set its root in its final pot.
