for that small tent as long as they are cool tubed, vented. I would just use the 3 1 k waters, plenty of light for that room. justput 2 lights in the back and one on the side. so you still can walk in . now if your talking trees, you vegging them 2 feet tall then flowering so 4 to 5 feet tall final size , you can put 6 plants per light so that's 18 and you can veg the other in a different room speed the process up , and im talking zero room to walk around ,really packed in, you will have to move plants and climb on your hands and knees to water them, nothing wrong with that, lol I have done it, also, you will need a ac unit, portable will work perfect, keep it proper temp. also to get you more excited. will yield average 72 ounces, more or less, and you will need to get a dehumidifier in that tent as well, so how,
