I just cloned 100 percent successgul using this method. Take some cutting fresh from your plants. Slice off with a razor blade. Take and while holding under water recut at a 45degree angle to paranoically
prevent air embolisms ( air getting trapped in stem) and then
take regular coffee can with plastic lid
poke holes in lid
place ro water up to limit
place lid one
place airstone in attached to pump
and then place cuttings into the coffee can. You should see roots in a few days. This one strain I have (I have two strains) took like 2 weeks though, weird but others took a few days. I have done this with nothing but ro water and done this with a few organic "helpers". liquid karma, etc. I did not even use cloning gel. Very easy. I am happier to use RR as they give a more stable clone but I am sure you have been told this already.
Take cut.
place in RR
use dome for 2 days
dont mist plants, just lid
wait. keep moist.
dont use any chems, it still works. I use liquid karma dip. 10 ml to a gallon of ro water. Also I dropped some bat guano in their as I hear P helps. I have 100 percent luck with this but it takes a little while longer than can with less success rate. Better clones tho. I will rip out a dwc clone in favor of a stronger RR clone.
