Alright, I'm having somewhat of a mental dilemma and I can't find an answer online anywhere. So, I grow on a west-facing balcony which means my plants get hit with direct sun from 2:30 in the afternoon until about 7:30 at night (slightly shaded, of course, with burlap). Before that they receive no direct sun at all, not even filtered light, as a roof is over them. It's still sort of bright on the balcony (due it being daytime and all), but like I said, no actual sun hitting them before 2:30. Does the mere ambient light they receive all day until 2:30 even matter? 5 hours and some change of direct sun doesn't seem like a lot, so I'm worried they'll never get enough light. It's not as though I can do anything about it, but I was just curious to know some thoughts and answers about whether ambient daylight is of any use at all.
