Here is the laydown for how I take clones and materials I use.
Materials:
Humidity Dome Preferably 7" Height
Plug tray & flat to collect water that the tray sits in
Rooting Hormone (Personally only use clonex)
Razor blade
Cup of water ph'ed
some sort of rooting plug ph'ed.
low light(floro tubes work great)
Seedling germination pad(kept at constant 90degrees.
Mister.
Take the mother plant you are going to clone and set up all your materials in a sterilized clean environment. Sterilize razor blades. Open rooting hormone (gel works the best IMO since it seals the end of the cutting instantly which stop air bubbles from pulling into stem after cut(if air bubble pulls up, water/nutes are blocked). Within 20 seconds make the cut, dip in gel, and place in hole of plug about 3/4-1" down,try and bury a node if ya can. Rinse and repeat. The cup of water is just for an emergency if ya need to take a min, put in water before clonex.I dont use any nutes or rooting stimulator's other than the clonex and get over 90% survival rate. After the clones are taken, mist them gently,they will wilt for a bit no matter what,this is normal and they should spring back up the next day if cutting taken correctly. continue to mist once to twice a day and keep plugs moist.Place tray on heating pad and turn he lights on 24/0. My clones always root between 7 and 14 days, usually more toward 7.
Next time I take clones I will make a video and post it. I take clones from any part of the plant with no issues. I just make sure to pick the healthiest ones thats all.
