Sativas love the sun and thrive in warm climates. In particular, the extent and number of diurnal soil temperature fluctuations can be critical in lessening seed dormancy of several species. I ve also tried the glass, water method took around 5-8 days but once transplant to soil, Coco, whatever your using I notice the seedling takes long also to sprout out into the open air But with the paper towel method I ve seen mine sprout same day as planted so the seed must be thriving then once hits your compost mix it must still have that energy and burst through whereas the glass, water method I ve waited 4-5 days after pottin once germinated to sprout.
