Strain
Since I am a noob in gardening I can't tell exactly whether Cinderella Jack (CJ) is easy or hard to grow. From a beginners point of view I would say the strain performed very well. It was very forgiving and continued growing despite my mistakes like overwatering, underfertilizing, overlighting etc.
I applied LST by bending the main stem down to expose the lower shoots to the light source (though Dutch Passion guys don't recommend this). Since the plant was very bushy the leaves didn't have enough space to grow and prevented the airflow. That's why I had to defoliate quite a lot. I think it is better to let CJ grow naturally.
CJ has a very nice scent of pepper.
I would grow it again.
