Sorry I never ended up posting the results ahaha I did a rosemary cutting dipped in the gel then straight into soil, and another one dipped and put into a beer bottle with water.
Only the one in the water grew tiny roots in about 10 days but never grew any longer so I planted it to soil and it died....
I tired again with a passionflower cutting in the water but it hasn't rooted, although it still looks very healthy and it's been well over a month.
