Harvest numbers are in..
HPS = .6g Per Watt at 3k
Cobs = 1.1g per watt at 620w
QB = .9g per watt at 120w

I am happy with the harvest from this strain. She is a low to med yielder.. I dont much like her but my circle lovers her..

First off I would like to say beautiful grows , very impressive. Looks like those qb’s are kicking some ass!!

On a side note your g/w with hps is super low!! I believe you went way overboard using 1k de fixtures to light a 4x4 area. I feel like you could have used 600w de’s with no loss in quality or quantity which would have likely put you in the 1 g/w range right next to your cob fixture. I’m definitely no led hater nor am I a hps lover but I’m using 4 1k de’s to light a 12’x12’ room and it is stupid bright in there.

I have been looking into the qb’s and trying to figure if it would be worth the switch from current de’s I have but I’m feeling like I would need like 6 of your qb rigs to cover the same space my de’s cover which would only save me a few hundred watts and cost 3 x what my fixtures did.

Any thoughts or insight would be appreciated.

Quick question; you running your DE HPS lamps at 1000W or the 1150W setting the manufacturer recommends?

DE's give the best bang for your buck

No, running at 1k I have never run my ballasts on super or anything like that, never heard of any manufacturer recommending the 1150 setting. As far as I knew they are bulb rated at 2100 Umol on the 1k setting, seen them tested at 24” at 1900 umol.

Day 10 flower today.

I’m interested as hell in led and I feel like they where really edging the market for a while and the the de’s hit the market hard. I still see led companies comparing there lights to 1k se lamps but what about de’s? Hence the reason for rolling through this thread because op said he was making the switch but then saw he was covering a 4x4 with a 1k and realistically he could have used a 600 which would have edged him right up to his cob fixture in gram per watt.
