Looking back I think I planted the seeds either late may/early june and they germinated sometime in mid-july.
I tried planting some seeds in several different conditions suggested by the stickied threads on growing Neps from seed in this forum. I tried some in just pure long sphagnum moss, some in peat/sand mix, and some in peat/sand/LFS. Then I had duplicate sets of each of the soil types and one set I put in the dark for 10 days before placing at the same windowsill as the others and the other set were on a well-lit windowsill immediately after sowing. I also tried to sterilize the peat in the oven to sterilize it, but didn't do anything to the sand or sphagnum moss in the mixes. All pots were placed in clear plastic sandwich bags and tied shut after planting and watering, with only occasionally opened to check and see about germination and water...although they didn't need water hardly at all since they were in the bag and stayed nice and moist.
I got no seedlings from the pure LFS pots...I don't think I had moisture consistently right with them or maybe the moss wasn't really great since it was the dried bag stuff from home-depot and not nice Live-LFS...
The peat/sand was o.k but the peat/sand/LFS mix was by far the best and is the soil mix for the pot in the above picture.
Now about the different light conditions I can't really say one was by significantly better than the other. I believe the pot in light immediately was better and is the one pictured above but I am kinda irritated because the tag labeling the different light conditions fell off from the bag. Basically for me the best conditions were seeds planted on peat/sand/fine chopped sphagnum moss and *pretty sure but not 100% confident* in light immediately after sowing, although the second pot of the same soil mix of peat/sand/sphagnum moss also germinated pretty well, with the peat/sand mixtures close behind. Mostly it seems like the soil was more of a factor than light for me, with the best combination being planted in peat/sand/LFS with light right away (I think...stupid tags running away...grumble)
The pots all were just at windowsills inside until mid august, and since then they are now under artificial lights and are growing rather quickly...at least a lot faster than I expected based on what I had read on growing neps from seeds online.
They are still in their little bags too, although I may try picking out one or two seedlings to put in their own mini pots and to acclimate them to non-baggied conditions to see how they fare and to help determine when to de-bag the rest of them, but I'm in no huge rush.
