+- 10 days for me too. Even dug that seed out after a week thinking it was a dud and found it had a taproot so I replaced it. It is a blue widow freebie growing just fine now. I probably would have thrown it out if it still hadn't germed, but if I paid for the seed I'd probably wait at least 2 weeks haha
FYI I don't germinate my seeds before planting them so these were just soaked a little and put into promix so they may have taken longer than others.
^^^^^^same^^^^ dumped a cell pack of coco seed that didnt pop into a bucket going into flower and found them on thier first true leaf during harvest...go figure.
I don't give up as easy since I had successful germination after 8 weeks. If they are valuable and don't pop after 2 weeks, I stick em in a pot heading to the flower room now.
I have had many seeds germinate at 1000 - 1300 ppm now, anybody else experienced this?
i use plastic wrap over my cups of soil and if they haven't sprouted after a week i go ahead and remove the plastic and let the soil dry out a little and wait a few more days. sometimes they sprout when the soil gets to the right moisture level.
I just plant the seedling straight into Promix and water enough to soak it really good. One time I waited 2 weeks and gave up, put the cup at the side of the grow and after a month I saw a little sprout peaking out from the soil. She eventually grew into a healthy mature plant. That was a total of six weeks from planting to sprouting!
So now I routinely wait a week and then place the cup aside under a light and make sure she is moist, and sometimes I will get seedlings coming up that I previously would have thrown away. Seeds are expensive, so it pays to give them a little more time. I don't believe IMHO that a seedling sprouting earlier than another makes it more vigourous in the long run. Just my 2 cents.
