2000 watt setup?

i just got a really good deal on 2 used 1000 watt lights and ballasts. These are going to be used for flowering so what size tent should i be looking for and also how many plants can i comfortably do with 2k watts?

2000k is alot for a tent unless ya get a huuuuuuuge one 4x8 min look at the 10x10s

and if they are not aircoolled i would not put them in a tent it would get way to hot
