If I were you I would go with that Canna coco you posted and get a simple set of fertilizers to get you through your first grow as trouble free as possible.
For the nutrients, I use General Hydroponics Flora Series. Just get some General Hydroponics (GH) Calimagic, GH Flora Micro, GH Flora Grow, GH Flora Bloom and, if its available in your location, Great White Mycorrhizae. If you cant find Great White, then I would go with GH Florakleen. I have my own recipe I use that is a good starting point, I can share that if you want at some point.
So in total your looking at 4 bottles of nutrients and a bottle of root powder, pretty simple imo.
Your also gonna need a PH pen, like 25 bucks, and a EC pen, also like 25 bucks. You use those to check your fertilizer solution.
It might sound complicated at first, but its WAY easier to fix problems like PH in coco vs soil as the plant will respond right away to fixing any issues. Soil takes a while to show improvement after trying to fix something, so you can end up chasing your tail a bit. Coco is like: you follow the recipe, you will get results.
Also, 16 litre pot is a bit too large for coco coir imo. You should rock something like a 7-11 litre pot instead, so you can get the full benefits of coco like fast drainage.
You dont need perlite (the lil white pellets) in the coco coir, pure coco has all the drainage you need. Adding perlite just adds another unnecessary step.
I like use hard sided plastic pots, or plastic grow bags. The fabric pots tend to dry out quicker than the plastic ones, making it a bit more crucial to moniter the moisture levels in the pot.
Whew that was a lot of info lol. If you end up going the coco route I will gladly help you along the way, its not as hard as it might appear
