The light requirement is rarely mentioned in assisting recalcitrant seeds to germinate, but I had observed as much in other conifer seeds which reproduce in sphagnum moss bog situations. To enhance seed production for this type seed (including the Austrocedrus Chilensis, Sequoia, Metasequia and others), take ordinary packaging bubble wrap. Cut it into 6" wide strips. Spread out your soil medium on it about 1/2" thick, and drop a seed on top of the soil every 4", about 1.5" from the top edge. Then roll the bubble wrap with the soil and seeds, nice and tightly, and tape the finished product, which will be a cylindrical shape. Place it into a growing pot with the "top" edges of the mixture "up", then water it. Set it aside in a partially shaded area, and you will get uniformly lighted seeds which will germinate uniformly. They will yield much higher than the ordinary germination rate, as Michail has observed with his bucket example.
If anyone in the United States has some spare seeds of the Fitzroya Cupressoides, please contact me.
