Sounds like you have a good plan.
My advice is be careful not to put them out to early unless lighting schedules are adjusted to the outdoor light schedule.
This is the number 1 mistake most make, and their plants go into early flower, then re-veg, and that causes lower yields and sometimes affects the size.
Good luck
Problem with growing big plants in Colorado is in reality the short season and relying on mother nature you have a very short veg season you one must have all the P's and Q's in order and with max light hrs pick a strain that does not flip to bloom @ them hrs.
I have grown strains that from clones will flup @ 14 hrs of light
To the above poster that is incorrect the warmer or hotter then will in fact create less density and more larfy buds just look at Sativa leaning strains compared to india leaning buds
the reason is to help keep the plant or buds cooler
Fact is colder temps increase bud density
But again for instance morning temps are 6 degrees light hrs per day 11 1/2 ??? but being old temps plants are not growing untill tey hit there minimal range Arounfd noonish now you lost most of the days light your doing 7 hrs literally and hoping for clear skys at least or its even less light hrs
