i use it with my clones. IMO it is more beneficial as a root stimulant than anything else. But like i said thats just my opinion. When i use it for cloning i use about 10 drops per gallon even more sometimes. I have to admit sometimes i dont even measure i just dump some in. So im gonna have to say that it might help during germination, but i wouldnt start using it till i could see a seedling poking out of the medium.
