Cloning Outdoor Plants for Indoor Hydro

I have a few outdoor plants growing and am getting a new Hydro system set up now.

I don't want to deal with buying seeds over the internet, so am wondering if I can clone the outdoor plants for indoor hydro growing?

Any advice much appreciated!

yea you can clone em are dey outdoor strains?

I honestly don't know. I got them from a friend and I think they were started a bit late since they are now only about 6 inches tall. I am going to give it a shot regardless, but I was wondering if there is anything different I should do? Perhaps spray the clippings with a watered down fungicide?

You can clone them OK but if they're sativas they will grow big. It's alright if you have lots of room. Fungicide won't hurt but there's plenty of fungus indoors already.

Thanks. I was going to try the "Sea of Green" technique so will force them to flower pretty early. Hopefully that will keep them from getting huge if they are sativa's?

This is my first grow, so am flying blind.
