Nope, the point in cloning waxes and horticultural oils is to seal the upper surface of the leaf against moisture loss. The plant does make its own thin waxy cuticle, but this may not be enough to protect it from dry air when it is going through the stress of cloning. So I guess you can say it is like a little portable humidity dome on each leaf. Be careful not to overapply- you don't need much.
Another bonus is that both neem and coriander oils inhibit fungal spores taking hold on your little plants.

stinkyattic Reviewed by stinkyattic on . help! problems with wilting Hello, Been plagued by issues lately with my grows, lately i've been experiencing troubles with going from clone(45w) to flower(i only use a 600w for starters), they wilt, each time the light is on they wilt more and more. But when its been dark for a period they are right back up there with the best. So the question is how is it best to harden the plant into the new enviroment? As everything else is more or less perfect, atleast compared to the veg room, only real difference is the light, Rating: 5
