I have had some clones in water now for 16 days now and still nothing. They continue to look green with no wilting or yellowing, but man.....
My cuts in water go for at least two weeks, but I
change water every other day. Lightly chlorinated,
pH to 5.8 - 6.0. Low light levels too.
Cooler temps, I use the passive vermiculite tubes.
If no wilt or yellowing your cuts will nub out.
Keep us posted
