Don't want to steal your thread but it happens that I'm also doing a small experiment , 3 days ago i potted up a few plants and today another 2. I'm also interested in the difference between peat and lfs. My plants are grown in a greenhouse (maybe this will also get different results). I think if the spagnum would get better results, it will only be a very small difference.
Anyway:
Oh yeah, I'm using peat with an amount of perlite and chilean spagnum moss :)
