Ive done seedlings ' back in the day '
I'd advise keeping the seedings on the longer side in the same pot
then replant more than two of each in separate pots ( one plant / pot )
and see how many make the transition to single plants
then decide how many single plants you can keep to get to the seed stage.
some single transplants might not make it , but you've maximized your single plan yield.
in more detail : let all the plants grow in their original containers ' for a while '
the timing is up to you for the transplant. the transplant the all into at least the same
size pot . make sure the soil in the original and the new pots is moist .
take the seedings out of the original pot , and gently break out the individual plants
and repot in at least the same size pot , wet soil , gently tapping down to eliminate
any air pockets , and keep the new ly potted plants moist , not wet
out of the sun for a few days . as soon as you think they are doing OK , then sun
and don't be in a hurry to discard any plant . keeping 3 is better than 2 ,
by over 50 % thats what insurance is for.
good luck.
Id bet there are more seeds in Indonesia , just in case . !
