As many have mentioned, the more sun the better. Not knowing your situation, it's hard to say what will work best but...
If you have marginal backyard sunlight, consider a moveable container. A bit of a pain in the ass, but you can move it to chase the sunlight as day or season shifts the light / shade patterns. If you want to get fancy, you can even use supplemental electric lights as long as you don't mess up the flowering light schedule once you've begun.
If you're going stealth mode, a little trimming or bending of branches can be helpful to let in more light. Back in the helicopter days, we liked to be careful about making fresh cuts on trees and limbs which were easy to see. A bow saw can get shrubs cut low to the ground (quiet too) and forest debris can camo the stump etc. Or you could use a dull spray paint to obscure any fresh cuts that will draw attention etc. Be creative and don't leave unnecessary signs etc.
7 hours is totally fine. just take in account the sun moves in the sky and at the end of the season will it still give you 7 hours of direct sun? lesser hours also means longer time to finish flowering. more chance of moisture staying on buds and not evaporating early enough in the day causing issues like pm and bud rot.
is the sun direct in the am? or pm?
long of the long. youll still grow worth while buds no doubt but dont expect as full buds.
this plant was grown with 8-9 hours of direct light that diminished to 5-6hrs at the end of flower. here she is a few weeks before cut. (early a bit due to bud rot and a forecast of a week of rain) still nothing to shake a stick at.
