1st grow questions

Okay so I'm planning to grow for myself and not to sell

I was going to get 3 auto mazar Dutch passion seeds for £23

Then for soil I was going to get biobizz light mix 20L for £7 to start them off then transplant to biobizz all mix 50L for £16

For fertiliser and nutrients biobizz grow, bloom and topmax for £35 and super thrive vitamins for £7

I was going to grow next to a lake to reduce the amount of time I need to water them but could this lead to them getting to much water?

Should I still plant them in pots or dig a hole in the ground and then put the soil in or cut holes in the pots

When do I transplant them? I was only planning on doing this once

And when should I start using nutrients and fertiliser how much and how often?

The only thing else I can think I would need to buy is a ph tester also I'm buying everything off the Internet and I have to grow it outside, cheers
