Supplemental indoor lighting for my balcony grow -- Help please

Hey everyone. Moving in a nice direction with my autoflower balcony grow (germed 4 of 6), but I could really use some advice/input on a light issue I`ll likely face throughout the grow.

My ladies get a nice amount of direct sunlight on a sunny day (approx. 7 hrs, plus a couple more of ambient daylight), but the climate I live in tends to have a variable weather pattern (northern hemisphere mountains).

Could I please have some opinions on whether or not I should supplement my natural outdoor lighting with some CFL`s indoors on cloudy/rainy days. I know photosynthesis occurs even on cloudy days, but I`ve heard the UV rays are bit harsh on those days, not to mention the obvious lack of direct sunshine which can lead to lessened growth/development.

I`m planning on using a very remedial home setup...nothing professional...2x 23watt CFL`s, 6500k cool white daylight during veg (then 2700k during flower), a few inches from top of plant with foil reflector rigged up for added intensity. Any comments? Please keep in mind this is only a supplemental regimen for a very small personal grow of a few plants, whereas my outdoor adventure is going to be the main focus for growth.

Looking forward to absorbing some knowledge from the community. Thanks in advance.

not trying to be a dick chickenp, but honestly, is that a serious question or are you f-ing with me? ever here of places called northern cali, the colorado rockies, montana, alaska, british columbia...not much different environments than the alps. so yeah, you can.
