Germinating using paper towel in a ziplock bag

Hi, this might seem like common sense, but all of the posts that talk about germinating using a dampened paper towel in a ziplock bag method never indicate whether or not to close the bag.

So I was just wondering whether everyone normally zips the bag close or keep it open to allow air exchange.

Thanks.

close the bag is the way to go son!

keep it air tight, less evaporation keeping a nice moist environment, think of a baby in a womb

Thanks for the quick replies

Hopefully I'll have some pics of seedlings to show off soon

seedling is hardest part for me lol. idk why just don't touch it so much

Try a shot glass with water and 5 drops of hydrogen peroxide...100%
