Also, here is a picture of the two Sal EL/Gene airlayers I made ~4 weeks ago (7/28) with plain old soil. I'll cut them off this week, and I like to cut off with about this many roots, although I know some guys around here wait till the bag has so many roots you can't see the soil anymore.
The first two pics are at 20 days after (weekend before last). The last couple of pics are from Saturday, about 27 days after (this Saturday). If you notice, pics 1 & 3 are the same shot/same side, so are 2 & 4.
