Growers Choice ROI-e720 vs Momac LED NRG-SAVR 640

[GET MO]

Yall ready for another side by side? I was able to get a dope deal on the gc roie720 cuz my 500w cmh died on me, then Momac was gracious to let me test out they 640w led light.
This run is 8 plants on each side, mostly runtz(tall ones) with a sureshot, and 2 phenos of relentless genetics strawberry fire cough og. The runtz will be the heart of the comparison like vibranium was for my last side by side.
Growing in 1 gallon cloth pots, coco dtw with automated watering, using jacks 321 and trying out power si bloom.
Got a late start, these are 2 weeks in, will put up net and spread them out tonight.

Hey GM, how are you liking the GC 720? I know it's still early,but the feedback I've gotten on those are all very positive,with even heat distribution.Hell of a time for an icmag update.

U can see the spectrums are different from the shots. Some info on spectrums and stats

The roi is definitely more visible blue from the reflection. I think the leafs on the Mo light with more red are showing more veg growth. I was wondering if my 680s had enough blue, but if they have the same spectrum as your 720, they should.

Tagging along for the show mo

the momac (right) side has stretched a bit more. I was reading how far the lights supposed to be away, gc says at least 6 inches, momac says 12-24 inches. I noticed hairs dying on higher buds under momac, so raised it up a lil but the ones under gc arent effected being real close to the light. Bet this has to do with momac having diodes closer together on less panels vs the growers choice having leds more dispersed. Im wondering if/how this will effect penetration to lower sites...

GMT - welcome aboard!

some shots at 4 weeks... did some deleafing, plants been dealing with some cold, hopefully doesnt slow um fown too much.

Have you got a PAR meter to measure what they are getting at the tops?

Seems the right light has more red chips than the left one. The color is a little purple.

thats a professional looking room. curious to see the weight difference with the same inputs other than light.

 

[GET MO]

Both sides lookin nice, i think the 720 fillin in a lil better. It will be interesting to see yield as well as quality, im guessing the extra 80w in the growers choice should be an increase in weight.
Had some issues with the well water today,

drained and refillt n the second batch was clear..

want to invest in a ro machine, and maybe a simpler filter before hand to get water clean before ro.

heres slme shots lights out with the cell phone, ima try n get some better images in the morning...

Relentless,Karma,Top Dawg.....not neccesarily in any order.
they put in the work,and test their breeding stock.

People Under the Stairs is less known Nd smaller based ,but has put out some fire crosses.
