Northern Light question

Hey everyone. I have a few questions that I need an answer to. I hope someone out there has some help for me. I am going to be growing in my newly built TN "mini pot cave" (as violatorkush named it) and I need to know:
1. Best PPM for Northern Light (soil grow)
2. Nirvana or buyamsterdamseeds (heard mostly good things on both of them)
3. would 1000w hps be good enough for a 4x6 area? I'm thinking no.

My total area is about 22x18, but my sog areas will be 4x6 mini sections. Any help is appreciated.

3. would 1000w hps be good enough for a 4x6 area? I'm thinking no.

430hps - 600hps for that space

HMMMM interesting. I'm going by what I saw seemorebuds do with northern lights. He used 4x6 area sog (hydro) and was using 4 600hps and was getting over 5lbs.

1000 w is too much ur gonna burn your plant

Wonder how people get away with 2400 watts in only 24 total sq feet?

go with the nirvana NL#s.




peace.

Probably will. Still though nirvana WW is awesome and still thinking about Big Bud from buyamsterdamseeds.
