T5 sunleaves pioneer v111 grow attemp!!!!!!

Ok so i've decided to use these auto flower seeds i got from a friend.
The way i wanna grow these seeds is via t5 fluorescent.
I have plenty of question because this will be my first attempt
at auto flower seeds.

heat and coolortable ac 12k btu
medium: Rockwool
system:dwc
fans: (1) window fan,(1) inline fan (1) exhaust fan

strains:himalayan blue diesel,
eazy rider x russian rocket fuel.

Questions:
Light schedule? I hear leave it at 18/6 the whole way?
When to feed nutrient?
Is the t5 enough for 10-20 plants?they only grow about a foot i believe.
What light bulbs should be purchased for bloom?
I have 65k right now.
What's the harvest time?
I hear 45 days from day it sprouts?
Will this pioneer system put out enough for my ladies?
What's 432 watts of fluorescent equivalent to hps?


That's all i can remember for now all help will be grateful +rep
thanks

No way on 10 plants with a single t5 rack, you need more lights or less plants The t5 is more suited for vegging stage, which the autoflower doesnt have much of, just not enough penetration to get the dense single colas autoflower is designed for, maybe you could trade the 12k btu cooler for a light system, and a smaller cooler
