Germination time

[Ckbrew]

When germinating seeds with the paper towel method, after how many days from when they do not pop a tap root do you consider them non-starters and toss them?

If a tap root starts to grow then starts to develop brown around the edges, I take it that is not a good sign. What went wrong? To wet, dry, hot, cold? Ty.

Probably too wet.
I’ve found the secret to the paper towel method is to make sure the paper is only damp...not wet.

Yes that sounds right what YY says. But i had 2 fails without tails this month. After 3 days i toss them.

Funny I never had problem with paper towel been wet. But I make sure it's warm.

try soaking the paper towel with hydrogen peroxide and then wring it out a bit...I agree that the towel need only be damp not wet and the room temp around 21C. Older seeds can take 5 or 6 days.

I toss my seeds in a glass of warm water and leave in dark warm place. I get better results than using paper towels

[Ckbrew]

How long do you soak them? Place in media after soak and before tap root pops?

[MagicMike66]

Leave them in the water until they pop. Can be anywhere 1-3 days. Then I put them in a rapid rooter cube and put in a solo pot with whatever medium you use.

16 hours should be enough but be aware that even a taproot needs air so if they crack in the water and you leave them there it could stunt their growth....that's why most growers only moisten the seeds (never letting them completely dry out)
