Project from seeds to weed 1 cabinet

1. Panel nr 1 for my colege: 56% efficient : --> 0.5 m2

- 1 HLG185-c1400

2. Panel nr 2 for me: 64%efficient: --> 2,25 m2

-24 CBX3590 3500 K @700 ma
- 3 HLG185-c700

or diffrent Kalvin temperature (single or mixed) for example: 18*3500K + 6*5000K.

Guys, what do you thing? I am reading a lot of this stuff. If I am deaper, I am more confused. Please, help me

If it's just for flowering, I'd mix in some 3000 and 4000 but 3500 alone is fine.

not only for flowering...... for both phase..... whats your propose? change some 3500 for 5000 ? or
4*3000K
4*3500K
4*4000K
4*5000K ??

To tell you the truth, I'd probably still go with the 3500s but add a dimmer so you don't roast your babies. 5000 is supposed to be better for veg but 3500 will work for the whole grow.
