Hi! Great roots.
Make holes on the cup, and don't let the sun rays hit the roots. Also only transplant when it's really full of roots, and when it's dry.
Wish you a great grow!
@Magic_frequency, they are more susceptible to lost time. When you loose time on auto, you can't recover.
That's because they start to flower when they suffer any stress, and transplant is a huge stress for the roots.
Starting to flower early means reduced flower production in quantity and in potential.
That's not even "start to flower earlier" it might cause a stunt, where the plant stop growing for some time, and you will lose time of growing, and so on...
Auto should be disturbed the less possible. Only if you are doing really great, and it's really strong, then you might top or something. Beside that, auto are contemplation only... They know hot to grow alone....
Also, do you mind to """"lose"""" a plastic cup? Just make some holes and the roots are going to love it.
