Autoflower seeds and bulbs

After doing some searching and more reading on autoflower seeds I have one question. When do you swap bulbs as the plant will automatically go into flowering?

I was planning on 20/4 schedule with 4x 26 watt 6500k 1x 23 watt 2700k for veg and 5x 23 watt 2700k for flowering. I was also going to do 24 hours of darkness at week 3 then switch to flowering bulbs but that seems unneeded since it will automatically switch.

When does everyone change bulbs when it comes to autoflowers?

change them once preflowers show

im changing mine as soon as she starts shooting pistils from the top.

Do you have a picture of what a preflower looks like? Should I do any extended darkness period?

^^^AGREE^^^ You Change ur lights once you plants show its sex. That means it is entering the flowering stage. and how many plants are u planing on growing?

Thanks for the pic and info.

xgiovanni03x - I am debating how many I am going to do. I have 4 seeds and think I could do 4 in my box but not 100%. Look at my sig for my grow log and that shows my setup.
