I’ve moved your request to make sure my topic Outdoor Grower TRYING Indoor Winter Grow 2019 stays on topic.
I’m not growing auto’s this year. But if I was, I’d choose Passive DWC using the Kratky method for the grow.
Two reasons. Very low maintenance and once the nutrients and PH are set no adjustments are required because the PH remains stable throughout the grow.
This is what “I” would do.
Invest in a good sized reservoir tank (15 quid from Homebase)
145 litre with 4 heavy duty wheels.
Cutout 5 holes in the lid for securing net pots.
Buy hydroponic veg and bloom, calmag and silicon additives.
Ph meter, Ph up+down mix
Get 5 x 2-litre plastic bottles and make Kratky pots.
How my hypothetical grow 
would work:
Germinate and grow seedlings in soil until 3 or 4 real leaves show.
Prepare the Kratky pots with the weakest solution of veg nutrients and transfer the seedling. Gradually increase the veg solution until week 4 or 5 or strong signs of flowering.
Move the plants to the main tank filled halfway to a third with a 3/4 strength bloom solution, calmag and silicon.
2 weeks before cropping. Syphon out the tank, fill and syphon and fill with clean water.
I would expect a most bountiful crop.
Jim, that’s what I would do.
Very best of luck with your soil grow.
