1kW for 1,2m x 1,2m
600W for 90cm x 90cm
400W for 60cm x 60cm

Could you make the room 120cm x 60cm, then 2x400W
If you go with 1,4m x 1,4m you should get 4x400W

2 400 will give you32w per sq foot the optimum is 50.the 600 will give better penitration under a smaller foot print 2 600 would probably be my choice or 3,4-400,either way heat is gonna be your biggest concern

Thanks heat is what i am worried about that is why i thiught 2 400 watt instead of 2 600 watt

Start with acouple sealed air cooled hoods add an inline or booster fan ,Also check out grow room designs and equipment .I think theres a couple threads dedicated to portable grow rooms I believe 1 is the Secrect Jardins club.I'm sure you'll get alot of info on keeping one of those tents cool
Peace
