Ive found larger clones root easier but i can only fit a few under the humidity dome. if i run 6 cells, i have to take much smaller clones but i can fit a shit ton under the dome. they take forever to root though. i still like the little clones, theyre more reliable for me only because i dont have a whole lot of veg space so i can take more duplicates.
anyone else take clones sub 3" or so? i usually take them about 3" then trim the bottom and any side branches
