    Hmm, some seeds take a while to grow. Green bean seeds germinate faster. If nothing come out after 5 days, what could be some possible reasons? It does happen sometimes though. How many days is yours so far? How many seeds did you put?

    Where should I put the seeds, at the top or in between the cotton wool.

    Hi Preston,

    Both ways are fine, as long as the bean is in contact with water to germinate. You'll be also to observe better if it is on top of the wet cotton wool.

    Yes, Jie xin, you can start 1 day after planting, as long as 5 consecutive days are observed.
    Jeff, you can continue to finish the 5 days. I can collect anytime within the first week.
