Hi Ren ,
Yes definitely , 2000w, will be enough for just 15sqm or so … I missed up some numbers 
,
I think I’ll setup the summer with open space,
The room is 42sqm so I’m going to use 6 x 480 QB LED … in order to stay cool .
Then in winter I’ll close everything in multiple tents (I’m thinking of 3 tents 2x1.5x2 and run with CMH 630 … the heat will balance the cold outside … cause this space is isolated but doesn’t have heating .
Let everybody knows how it goes !!
