There are four sprouts left out of the 10 that i germed because of some stupid things i did. Of the four left 2 are them are 6 days old and the other 2 are just a day old.

The 2 in the styrofoam cups are only a day old they both sprouted on the same day. The other 2 older ones are in some plastic bottles i cut the bottom off of because i had no paper cups to put them in at the time and they had already germed so i just used what i had available. The one in the first picture is really small for 6 days old and im wondering if i should just transfer it into a bigger pot because maybe the little cup it's in is hindering its growth. The next one is growing tall and i had to tie it onto a toothpick to stop it from toppling over. The next 2 are the new sprouts and im wondering when should i start thinkin about transferring them into bigger pots?
