Hey Azure,

Welcome to the boards! :jointsmile:

You can plant your clone directly into whichever medium you plan to use, but I wouldn't plant it too deeply. I don't use rockwool myself, but I've heard stories of people having problems with root rot when transplanting rockwool too deeply into the soil. And rockwool does hold more water than soil, but it's my understanding that they're pretty hard to overwater. You obviously don't want to let it dry out, so I'd keep it somewhat moist (not soaked) until you intend to transplant.

And there are still some pure landrace sativas out there, but you're right that dominant indicas are the craze for lots of indoor growers. Most growers don't have the space to let pure sativas grow naturally, and would much prefer the shorter flowering times of the indicas. But, again, there's some good sativas on the market - Kali Mist is my personal favorite, but I've also had some outstanding results with a few of the Haze varieties.

Best of luck. :thumbsup:
