How much LED light do I need

[HolyGhost23]

I want this to be a sticky since the other thread went into a drama fest. (admins edit as they wish)

I have a 2x4 grow tent and id like to know if my 2 cxa 3070's with 210W draw is enough or should I supplement it with cfl and if so how much?

What's the area of coverage for your model? Like 2x2? If you have two of them it's exactly perfect for a 2x4 room. But there's almost ALWAYS room for more light hahah

No, more LED side lighting.

You should supplement. Its dependent on growing style/training method though. I have that amount + a little more in a 2x2 space just for reference
