Hi i need advise on propagating a large number of seeds

I'm a novice grower but have years of experience growing tomatoes. I have 200 seeds coming and this is my idea.

I am going to germinate the 200 seeds in rockwool cubes inside my large propagation bin and once they germinate I will be transferring them to jiffy pots and keeping them in my 3m x 5m sleepout I have 3 x 400w mh grow lights and will use until they are ready to go out into the great outdoors. I'm after some advise on

What's the best medium for seedling will seed raising mix work
Minimum temperatures to go outside unprotected
Soil soil mix that's best to use
Ph for soil and water source and best way to test

Much thanks in advance
