First Tree

Unless your germinating in a cool space and need the heat, no light is required until it sprouts. Cool temps will slow germination.

as soon as seeds germinate they need light to grow so asa they are above soil/rw.. they will be searching for it good luck

Be careful with the tissue method. Don't let it get too dry or you can damage the taproot. Everyone has their own method. Find what works for you. I personally soak the seed for 18 to 24hrs in rainwater (a lot of times you will see the taproot already comijg out), then just pour the seed right into the growing medium hole made 1/4 to 1/2 inch deep. Then just cover up and wait. Never had one not germinate that way and no chance of damaging taproot. Once I see them start to break ground, I flip the light on. Best of luck! Happy Growing!
