Hello everyone!

I'm new at this and trying to do less mistakes as possible so help is needed.
The strain i want to grow needs to have high THC and CBC (anti-inflammation), some CBD is also welcome.
All this in indica or indica dominant. I 'm between The Hog, The Doctor and Mazar. Anyone with the knowledge and/or experience for better strains please share.
I want to go for organic grow.

Hardware i hope i can find in Europe if possible.
Tent space 48x48x80 what brands have quality tents?
Light => Biggest problem as i see it, i 'm hoping to go for LED but how many watts and what brand? A timer switch is needed right?
What In/out fans and carbon filter for the size of tent. Two timer switches needed here?
Size of pots for better grow? Bigger pots better than more smaller pots?
4 small fans are enough to circulate the air the plants need?
Do i need a transformer for the light or anything else?
Getting green pad for CO2 at flowering stage is a good choice?
An equipment board is also needed?
temp/hydrometer, ph meter for water, ph moisture lumen meter for soil, 6 floor drynet, pipes, hangers for light.
Humidifier what size?
GuanoKalong Bat Grow/Bloom are a good choice to use or not?

Anything i missed?

P.S. Taking some time off to vape some critical lights, i'm filling dizzy with all this research...
