This is my result in 30 days. I use garden soil & a little bit of perlite (about 10%).

Jimmy, curious about how many times you had to add water to your set
up in 30 data? I only added water the day they were started.

whenever I water the plant, I also water the pot. Water still gets in the pot from the side and lid.

Mike, Maybe I missed it, but do break up or cut the RR cube? I have some root riot cubes and some of the rooting cups from bass but the cubes I have wouldn't fill the cup. I seen that you used two cubes but are they broken up or cut?

Ryan, I sliced the two cubes half into and put them end to
end around the limb. I then filled the remainder of the pot with
UPM

Thanks, it seems to work pretty good, I just separated my first air layer a couple days ago using the cup and potting soil, I should have left it on longer but after 13 days the roots started growing through the holes to the water reservoir and I didn't want it to grow to many roots into the holes because I was worried about breaking them when it came time for seperation, I guess I was a little impatient also, but it seems to be doing good so far.
