instructions say total of 10 seconds, 5 seconds with iron in one place and 5 seconds moving grow pod around edge of iron. mine came off eventually though so im sure a lil more time wont hurt
ya i decided to just use the ones wit herbs in them n pick out all the seeds cuz those looks like there on there good and i got 5 free ones when i bought my ag so i got like 50 pods
lol i hope it wasnt super glue super glue cuz its real toxic i did that n then thru the domes on n did some werid shit to the plant like turned it black now on i just use the pre packed herb joints then just take seeds out
