They grew 15cm this week. They are starting to slow down now in height and now starting to slowly focus on buds. The smell is showing up. The my are drinking more and more now.
The plants look good, but as these are autos you should get them out of those Solo cups ASAP. The roots find the limits of the cup and the plant gets stunted and won’t grow much further. Last year I found two weeks was too long and have switched back to peat pots instead. Good luck.
@Northern_Ent, they are all moved to the bigs pots now. I did it on Monday, so right after I took the photos I moved them. They are all getting much bigger now. Thanks for the tip
