Clone in Aerogarden

I have three female plants that have been in 12-12 cycle under HPS for just about 5 days now. I am wondering if I can take a clone from one of those females and put it in my aerogarden. I am totally new to cloning and have no idea. I am not sure if it is bad to take clones from anything other than a mother. That rhymes lol

ya aerogarden is great for cloning

well that's great news. how do I go about it? just take the clone and put the stalk right into the sponge thing?

yep use some rooting hormone too, i usually rip the sponge thing down the middle more so its easier for the roots to break through

great sounds good. thanks alot man

but what light cycle should be used for the clone to start, I had heard clones did not need direct sun. Is this false?

They should of been taken under 18-6 light cycle but i've heard people have success under 12-12.
