cloning question

How long should I leave my clone in the dark before introducing it to light again?

Why would you have a clone in the dark???

Out of direct light really, I read it helps the cloning process. I was just looking for thoughts on this.

OK, I've never had a problem introducing a rooted clone to more intense light... as long as it wasn't dark enough that your clones started to flower, and as long as you don't plan on putting them an inch under a 400W MH, then I'd say you should be fine.
