I have some blue city diesel seeds that I got that soaked for hours in a cup of water and transferred to rockwool cubes. They were fresh healthy looking seeds and they seem to be taking an unusually long time to germinate. I broke open a cube out of frustration today only to see one of the seeds still without a taproot almost five days later...what gives?????

What kind of temperature are you germinating at? I find around 25 degrees usually germinates within 24 hrs, anything less than 18 and your seeds could rot after a few days.

I've never tried it but apparently when some seeds have a tough outer shell its difficult for them to germinate, you can put them in a match box with some sand paper and shake it for about a minute to scuff them and thin the shell.

Idk °c
But 80-82°f will provide the best results.. ive also done expirements in 2° increments, 40 seeds in each group. And repeated my results many times at 80-82
The cup of water method will lower your rates

The method I find successful is placing seeds with sterilized tweezers into a clean glass half full of distilled ph to 5.8. After 12 hours place the seeds, which should have sunk by now in between 6 pieces of pre moistened (with same water) non perfumed tissue paper and place in the dark and at a temperature of between 26 and 28c (79 and 82f for those in north of the equator) By the next day, a taproot should emerge, then use tweezers to transfer the seeds gently into a pre moistened (with same water) rockwool cube or directly into the soil medium with the taproot facing in the direction of South.
