Thanks a lot everyone for all the input!
As said before, this place is amazing 
An interesting point is that I am not planning to use the full 80x80 and I’ll probably try to have 60x60 canopy, spread in a screen or small perpetual (I just want to play it safe). The remaining space will be used for utilities, ventilation and working area.
Yes it feels a bit of a waste of potential growing area (and yield) but I can always get a smaller tent and a new light later on now that this kind of lights are more and more affordable 
@Baudelaire SolStrips and Sheers look awesome! Thanks for clarifying shipping options
