Test room: DE HPS vs. Citizen COBs

[BMWEATER]

What y'all aren't figuring into the equation is that people have been growing with HID lighting for 30 years, while LED lights are still relatively new. The learning curve hadn't had time to catch up.

When it does, there won't be any doubt.

You talk as though it will take years to adapt. Remember we are in an accelerated time of technology for MJ.

We have libraries of data available online to our finger tips. Something that didn't come around till 2005/2006

We have more growers growing now then we ever have, that will also accelerate the learning curve

And finally we have our past experiences. We build on what we learn, we don't just scrap all the information we gained over the 30 years using HIDs and start from fresh. we build upon what we have learned and move forward.

Same or even warmer, believe it or not.

Ive used the day/night temp differential to control stretch at times. Keep it the two roughly the same and it reall works to keep tigh nodes. But.. i know when ive done that for too long i started seeing some necrosis start on the leaves.. couldnt figure out what it was ... thought it was salt etc etc and then it stopped when i widen the gap on the temp diff.

You havent seen that? Maybe i shouldnt be so worried about it?

No I never saw that.

I have finally got a chance to check out the northern grow, but was too late for pictures. The room pulled over 9 units and the LED's only lost by an ounce or 2.

He is very happy with the results and we are doing 2 4'x8' trays, 3 lights (500w,650w,500w) over one VS. 2 lights (950w,950w).

Any noticeable differences in bud density or frostiness?

Density and die-hard No

Frost and smell- LED better, but not by much. Noticable.
