I'm planning to grow in a cabinet that is about H5.2 x W3.3 x D1.8, and wondering about the lumen requirements. Due to my lack of English skillz, i'm posting this piece of MSPaint art.



I'm wondering about the lumen requirements. As far as i know, te required amount is about 5k during flowering, and that's hard to keep up considering the distance. Am i right, or is the amount counted at the canopy? Regarding watts, 250W should do, but considering lumen and my understanding of them, not even 400W will do...

Also, is Northern Lights good in this size, or would they be to big?
