It is very tricky to see soil moisture level by naked eye, Just slightly higher moisture level, mold will eat/kill young roots and rotten cuttings.
I use 3 - 1 meter, It seems work well, I think that you can buy it from nursery for less than 10 dollars, or If you don't mind to wait, I bought it from Chinese website for $5 shipping included.
I live in area with wet winter soils, I guess that it is very high mold spore counts, By using this 3 in 1 meter, I will stay away from those cheaper bag soils, they are too wet, I like Pro-max soil, It costs more but it is well worth for me, It is extremely hard to buy cuttings here.
I tried rooting with pure perlite, It must screen out those perlite's fine, they are mold heaven, It killed most of my cuttings.
I tried rooting with coconut coir, It works quite well for me due to its anti-mold ability, it is quite acid and mold hate it, Although it was badly molded on top layer of coir , inside of cup, no mold at all with many air pockets and roots love it.
good luck, my friend, hope to see all baby fig trees growing fast.
