Soaked the seeds in a glass of water for 18 hours then put in damp paper towels in a ziplock bag in the dark for another 2 days. Tap roots had grown over an inch and then planted in damp soil filled solo cups and sprayed with water. Put the lights and fans on. Gelato sprouted 2 days later after pushing up a big clod of soil.
Every couple of days watered around the edges of the cups.
On day 4 got info that autoflowers should be planted in their final pots so freaked out and transplanted them into 3 gallon fabric pots. Lost half the soil from the Gelato cup but luckily managed not to damage the roots. Some hardy girl :)
