New Grower Sour crack won't germinate

[Aunty Edna]

Good evening friends, Aunty Edna here again. I hope you are all enjoying the new school year and making lots of friends.

It's that time of year again, the garden this time is from Mephistos seeds. They came highly recommend by a very nice chap on here so I decided to try them.

2x sour crack, 2x fantasmo, 2x beary white went into normal seedling soil that has proven to work very well.
By day 3 the beary whites were up, by day 4 the fantasmos were up.
But the sour cracks did not pop up so I went in with a knitting needle to see what had happened but they both failed to open.

It's funny that the other 4 opened so easily but the sour cracks show no sign of opening.

What should I do to try and help them along?

Keep your at 80% not 45%

Will plastic wrap on top of the cup work?

 

[blowyourmind]

It Will work better .. In the beginning seedlings do best on 80%

They have been in 70% humidity for days now. Still nothing.

I always germinate in a wet paper towel and am about 45/45 with mephisto beans. I fold a paper towel in half 3 times then wet it(damp but not dripping). Get 2 small plates from the kitchen and put papertowel inside them (flip one upside down like clamshell) then the plates with seeds in them go somewhere with constant warmth. I found ontop of the cable box is perfect. Dont think ive ever had a mephisto bean take more than 48 hrs using this method, almost set a clock by them usually exactly 36 hrs later they will have a tail poking out.

Gl i wish ya the best, one of my favorite lil strains there!

Just put them in glass of water for 8-12 hours and then straight into soil. Pour 100-200ml water and wait.
