More questions! Do you ditch the floaters in the very first soaking ?
If the floaters soft or mushy yes, if I think the seed is solid and has any chance, I keep in... just in case.
3 months of warm. I don't look for anything to happen just maintain temp and damp medium.
Caroline, baggies work well because you can view things easily. It also helps keep moisture consistent.
Something as deep as a standard mum pot for depth. You will know when you see root length.
