UPDATE:
They have now made it outside and seem to be loving the sun. Imagine that, right? :d
It was an uphill battle trying to get these outside though, because of the rain. Every time I put them outside, the forecast would change it seemed. But it looks like a stretch of sunny days are on the way now, so I won't have to keep running them in and out of the house. The spot on the deck gets a good amount of full sun and shade throughout the day and as you can see, there is some new growth showing on the tops.
The rocks are large natural river pebbles, the giant one being an exception. I don't remember where I found the big one... I put them in the pots mainly for aesthetics but also to help prevent wobbling when moving the pots around.
