Red Solo Cups || Transplanting Question

How long should you leave seedlings in red solo cups before transplanting them into a large pot? My seedlings are about 1 week old, is now the time?

Thanks in advance!

1 more week

yea at week 2-3 is normal I guess, depending on your grow rate ..

Thank you everyone!!!

It might be over a week... i'll take a look at my notebook to confirm!
