I know....there were posts in a recent thread that suggested that
root might not like the perlite...well, that they preferred other materials
that had been mixed with the perlite.
Clearly just perlite works fine. We knew this though....the dude who saw
better growth in the coir mixed in actually did see what he reported, so this
will deserve further consideration.
I have grown mushrooms in outdoors SGFC and have seen for years that
seeds blown into the box germed, grew, and flowered with nothing but
perlite to root in.
Take care,
