Gorilla grow light fencing question

I have three Urban Indigos planted and discovered the direct sunlight they're getting is only about 5.5 hours a day. I think it will increase towards summer. I can't move them. It is sunny everyday tho where i'm at. Two are three weeks old and 10" and bushy. The other is 9 days younger and much smaller. They look healthy and good. Any ideas how my yield will be effected with the sunlight situation?
Also, when is it safer to take off the chicken wire cages I have protecting them (from deer)? I've read at a certain point the deer don't like the canabanoid taste in the leaves and leave them alone. Thanks.

With 5.5 hrs of direct sunlight you'll be ok.....leave the chicken wire,bend it back if you have to but use it to help support the plant.Deer are after the leaves not the buds so you have a ways to go.Someone on Riu recommended one of those motion activated toys placed near your plant to scare away any critters,I always thought was a good idea.Put it in a gallon ziploc so rain wont ruin it..predator piss works good too(academy or other outdoors stores have it).GL.peace
