For outdoors starting them indoors under a grow tent or greenhouse is excellent.
Green mass and overall look of your girls is great.
Don't worry about stretch now, if you keep the good care, or if you transplant them to even bigger pots (or soil), they will grow higher than your house.
The biggest concern for outdoor crops, are pests and not being able to control weather.
You can mitigate this by keeping very good track of the status of your girls, if you can watch them daily or twice a day, stems, bottom of the leaves, main branch, overall color, and be prepared to act quickly.
Some bugs have pretty defined seasons, and those some times are just 2-4 weeks, so keep taking notes about your backyard, and keep learning, you need at least one or two full yearly seasons to get to know and control as much as you can, and you never stop learning.
Best wishes to you and your girls, and you know anything else you can always raise your question here or ask privately without any hassle :)
Happy smokes!
