Reposted one of my old posts on what I do for cloning:
Just cloned last night. Many people have their own cloning techniques, but here is what I do and get a 2-5% failure rate. (usually 1 or 2 out of 40 clones will die)
Materials:
Healthy mother plant
Clean Razorblade
Bowl of Water (RO)
Small bowl of Clonex Gel
Large bowl of 50ppm Nutes:
--Aqua Flakes A + B
--Roots Exelerator
--Algen Extract
--Drip Clean
Bag of Rapid Rooters
1. Put the rapid rooters into the 50 ppm nutrient bowl
2. Put the wet rapid rooters into your little clone holder tray
3. Make cuttings
4. Dip the cut immediately into water. (I swish it around a little bit.. more of an Obsessive Compulsive thing than anything else)
5. Dip in Clonex Gel
6. Firmly place the cutting into the rapid rooter (firm contact with the medium and the cut)
7. Cut the fan leaves basically in half (reduces water loss due to evap)
8. Spray RO water all over the cuttings in the tray
9. Spray the inside of the dome
10. Put the dome on the tray
11. Once a day at 7pm-ish I spray the plants, spray the inside of the dome, and put it back on
12. In 6-7 days I pull the dome off and put them in rockwool cubes that were soaked in 300-400ppm solution. You should have tons of roots at this point coming out of your rapid rooter.
13. Don't water your rockwool for 2-3 days
14. Use 350ppm nute solution for the first week of rockwool, then jump it up to 400-500ppm for another 2 weeks
15. Flip your plants (12/12)
For Rockwool cube size, technically you could flower in a six-inch rockwool cube, but I prefer to transplant them into 3x3's for 3 weeks before I put the plant into Hydroton in a 3-gallon bucket.
Edit: I used to use 150ppm nutes for first week of rockwool, but I've been using 300-400 with no problems
