Keep my see 1k hps or switch to cmh???

So I'm looking to revamp my current flower room. dimensions are 9ft long, 6 ft wide and 7 ft tall. I'm running 2 trays with 2k hps phantoms now but am looking to go to 3 3x3 trays and either add 1 more 1k or swap all 3 for cmh. I'm not looking to decrease my yield or quality, only my temps. Any cmh that produce an output similar to a 1k hps??

Keep those 1k if you don't want to lose yield and quality imho. I did a side by side with a 1k and a de 630 and the yield was half. 4x8 flood table with 1k on one side the de on the other side.

Is there any way I can make my 1k more efficient?? I'm trying to maximize my growth without losing quality. Is there a way I could use my overlapping light to cover a 3rd tray without the plants on the ends becomeing too stretchy?? My rooms wiring can't take another 1k on it...

I won't go back to hps. CMH kills it in every way. That being said... the bulb matters. You want a genuine Philips brand 315 bulb. Far as I know, Philips doesn't make a DE 630 so I wouldn't trust any of those to be good quality. In my room, a single 315 yields like a 600 hps with better quality terps/resin.

There's hoods with double sockets that would be equivalent to a 1k hps. Issack had a great side by side recently with the Nanolux dual 315 hood and Philips bulbs vs hps 1k's.

I'd go with those.

Would a 630 be closer to a 1k than a 315???

What sort of coverage does the 630 produce? I just do 3x3 trays...

Just get a MH Blue and you'll have a better bulb no need to switch ballast/hood and all that. Eye Hortilux is the MH Blue I'd recommend, damn bulb is expensive. Flower with HPS then last 20 days finish with MH Blue.
