Turn them on! They’re ready for you! They need light to grow towards to and the heat...
Ya I’d get the light on as well. 3/4†Is a bit deeper then I plant them. Also make sure the tap root is facing down. GWE has a great tutorial on this http://www.growweedeasy.com/germinate#plant-your-germinated-cannabis-seeds hope it helps and good luck!
If u can put a humidity dome on top and spray twice a day with phed water till thay pop. A dome can b as simple as a cut down water bottle or a sandwich bag.
Leave the light on 24/7 and remove dome after thay pop, keep them warm and moist but don’t overwater. My 2 cents
