Outdoor Autoflower question

Well I am so happy with the weather lately, 28 - 29 C which is 82 - 84F. In the last 5 days my White Widow has grown 2 inches. Day 50 and she is 12 inches tall. I wonder at what stage they stop growing? hmm...

White Widow Auto Fem from Vision Seeds - Day 50 and Super Skunk Auto Fem from Vision Seeds - Day 3

This is my White Widow on day 58

Vision seeds website says that this finishes in 56 days, this is already at 58 days? can anyone advise?

Ok so I'm stoned off my nut and have thought of a question in regards to outdoor growing in general which, to me seems like a really good questions but it could possibly be a really silly one.

Does the moon, when bright, help ur plant to grow?
