Mini greenhouse supplemental led question

Mini greenhouse grow that gets the afternoon sun from 12-4, I timed my 300w led to turn on 8am-12, then 4pm-5pm. Is this a good idea to time with natural sunlight or leave on all day? I live in Florida, so pretty mild spring. Greenhouse is kept from view, so I can't do morning sun. Also any thing I could do to maximize my growth? I'm using smart pots with fox farm ocean forest with a fan blowing all day. Afghan auto seeds. Thus is my first grow.

With autos the more light the better. But running the light in the morning, with sun the rest of the day sounds good.

Most folks do outdoor autos in the height of summer.
