Hey Buddha, I'm kind of a strict up pot guy , especially with seedlings , since they are a bit more fragile
But in the case of a strong clone going outside , I've had good luck going straight to final large pot or even directly into ground , I feel like when they take off under the sun , there will be a deep root drive and you can just let them get their feet going as long as you can maintain a decent moisture consistancy , you know , without creating a muddy bottom that will inhibit good root movement , I like to stand over my containers with a mist setting on my hose till things take hold , being careful not to drench the new transplant .... Then I think you will be fine and in 2 weeks , healthy root should take hold
Just my experience , others may disagree
Hope that helps
