That’s BS. Every strain will root. Even a tree; took cuttings from a Japanese maple that rooted right next to my sour diesels and blueberry headbands. You could root a fucking pencil in this thing…
You can have anywhere from 1” to 4” hanging down into the cloner. Will root as long as they get some water pressure. Droplets seem to make them root faster. Seems like very long stems take longer to push roots but they will…
What am I doing wrong then? Like i said 1 strain out of 5 rooted perfect in 9 days, perfect... The other 4 half lived and the living ones looked like shit most of them.
-I cut clones that are about 6 inches long from a healthy plant at 45 degree angle with very sharp scissors
-dip into a rooting gel
-put in dewey mister under a 40 watt veg bulb that is 4 feet away, also got a little indirect light from a T4
- Add clonex to the water so the ppm goes to about 325, out of tap the water is 160
- Dewey mister probably holds 1.5 gallons of water and besides the clonex I add about 3ml of uc roots. Sometimes ph down
