Caliban The clear cup is not good for roots. Any light will stunt root growth. The roots won’t expand to the sides due to light and the plant remains small.

NopeQQ they don't like light either

Apichayo I understand that roots do not like light. But this is my first planting. I want to see his growth.

jack1997 Isn’t light bad for the roots

jack1997 Try using a non cleaner cup

Apichayo I'll try it the way you said it. Thank you bro.
