if they are wilting you need to increase the humidity in the chamber. Ive mastered the cloning process and have a 90% survival rate. most pop visible roots in 14 days. Very simple:
you need to have your cloning chamber in a seperate room from your other plants, because the humidity is too low in such an environment. i use a small closet and make sure the temp is about 70 in the closet.
-Get a large styrafoam cooler, as they keep the clones insulated.
-put a raised rack of some kind in the cooler, with some water under the rack...this keeps the humidity high but not too high. make sure your cups dont touch the water.
-painters plastic goes over the cooler and make sure its a closed system with no air leaks.
-put a floro on top but droop the plastic so it doesnt touch the light. the temp will raise too much otherwise.
-spray the inside to raise the humidity and spay daily for the first 4-7 days keeping the plastic closed.
-i use rockwool (about an inch cubed). Soak them, then squeeze out the water so they get plenty of air.
-clonex works great and you dont have to worry about fungus, as it has an antifungal agent.
- after about a week, you can take a corner of the plastic off so they dont rot or have mold issues. they should not droop at this point, but if they are drooping a couple hours later, replace the plastic and spray them again.
-its no work after these firsrt couple days. just make sure your cubes dont dry out, or are completely soaked. White hairs will bust out, at which point you can put them in dirt or a larger block for hydro. I dont expose them to normal humidity levels for a couple days though. i put them in their larger container and let the roots take hold for a couple days. then they can come out into the veg room.
