Thanks for the great replies everyone, that was very helpful. Also thanks for all the pictures of your own setups
I will definitely go the greenhouse way, I had been thinking of setting one up anyway to grow some veggies of my own, so I might as well expand on that idea a bit to make room for some cacti.

I'll look a bit further into LED (ideally) or fluorescent light to raise seedlings (I've read fluorescent lights are also great for salvia, so I could maybe use it for both), then move them to the greenhouse once they have grown past the seedling stage.

I'm excited for the future

Thank you again for all the advice, this was most helpful, and highly appreciated.
