can't find the pics and not sure who the user was but basically he just cut huge pieces out of the solo cups so basically the cup had NO support. and the entire bottom was just a huge X and i think he just double cupped it so he put that cup into a regular solo cup so he could just easily remove the 1st cup and transplant it imo it's just too much work your better off just transplanting out of the cup it really isn't hard. easiest way is to take an empty cup or the existing cup and put soil or medium into your new pot and back fill around the cup so it has an indent of the cups shape then simply slide the plant in. just leave more space if you want to back fill the stems if they are too leggy and plant it slightly deeper.
