Should be good for 4...6 might be pushing it, depending on reflection and space.... check my lighting charts in my sig link....... Luck.

My space is in an attic i am painting 2 walls now matte white and the seedlings box is matte white aswell.. The area i have it about 4x4 ft and about 8 foot in height.. will this get 6 plants? i not even sure howmany i will get i have 5 germinating and 2 planted under a desk lamp till tomorrow when i put them under the 400w

It's fairly likely that you'll need more than a small fan to keep the room cool when you crank up the 400w. Have you done a dry run with no plants? And left it for a few hours to settle at a temperature? You might be surprised how hot it gets.
You will get 6 average sized plants in a 4x4 area but I'm not sure you'll have enough light for that area. Your average 400w bulb will poot out 3-3500 lumens per sq ft in that area. The bare minimum for growing plants is 3000 lumens per sq ft, and the optimum is 7-10,000.
My 600w is enough for 6 plants, occasionally 8 but they have to be quite crowded or the outsides don't get enough light.
Of course if you do a SOG and lollipop the plants, you could fit more in there, but the square footage that light will cover remains the same.

Ill look at the fan properly and tell you how many watts and volts it has.. Its not really that small its an eletric heater but has a fan mode

Ok the fan is 2000watts and 230volts.. And i think i will just do 4 becuse i have 2 seeds planted and 4 germinating and i dont think they will all germinate so ill stick with what ever outcome i get and hope for the best as a first time grow

Goodluck bro. my 2c.. get your grow room sorted 100% before you put your plants in do a test run and make sure the temps are ok.... nothing worse than having to construct or "fix things" when you have plants in there..

Thats whati alreay had to do i had tinfoil up and i head that was bad to itook it all down and had to move my plants for a while.. Thanks thats all over with now.. The attic will stay between 18-26 degrees celcuis.. This will be ok becuse like they grow in the wild and it does not stay hot and at the same temp all day every day

Right so you just have a fan blowing air around in there? No exhaust fan to get rid of all the stale air? No passive intake to allow fresh air in? And you tell us you don't want any more ventilation?
Fair enough, although the air will soon get depleted of co2 and there's a good chance you'll suffocate the plants, unless you're adding co2 to the air.
If you get around that there's still the question of where the heat from your light is going to go, unless you wanna turn that box into an oven...
Oh btw, the 2000w refers to the heating element/s, not to the fan itself. Wattage isn't really important when talking about fans, what you need to look for is the cfm (cubic feet per minute) rating, but as it's a heater you have I doubt it gives one.
