Do i need a inline fan for my 2x4 grow tent?

At the moment I got 4 led lights in my 4x4 and the temperature is at 90f I was thinking that's way to hot so I'm gonna take one led light from that grow tent and put it in a 2x4 grow tent? I don't want to spend extra funds for a inline fan. Could I just use clip on fan?

Also those 3 lights are 505 true watts total is that enough for 7 plants in a 4x4?
And my Mars Hydro eco is 205 true watts is that enough watts in a 2x4 for 2 plants. I prefer to use all 4 LED's lights in my 4x4 but I can't it's to darn hot.

Thinking about getting a other 4x4 in the future. I'm looking for 1 led light that covers the whole area and good for heat wise. You guys recommend anything less then 1000

Thank you

And is 90f to hot??

Yes, you need an inline fan and should also have fans in the tent for circulation. Exhaust fans are just as important to manage humidity as they are for heat. They also help keep the air from going stale in the tent.

505w in a 4x4 is fine. Averages out to a little over 31w/sq ft which is pretty close to the recommended amount.

When you say inline fan are you referring to intake or exhaust? Because you most certainly need an exhaust fan. I've never needed an intake myself, passive has always been fine, but in places with higher ambient temps some people do end up needing them.
