Outdoors here. In the past I've tried going directly into the final pot (10-15 gallons) once the clone is well rooted and the plant somewhat developed. Just an observation but it does seem to work better to transplant up, when you move from one container up a size, typically the roots have filled up the small container and are eager to expand once more room is available, which makes growth really take off.
The main issue I've had with small plants in large containers is overwatering. You're making a shitton of soil wet, and it mostly sits there aside from what's by the roots that can be taken up, which can lead to root rot. It can be a real balancing act, which I don't want to deal with.
