6" x 22 " 558 samsung 561c led panel

Day one of clones under two of these double grids

will veg for week or two then 9 of them will go under the 6 panel grid @600w for flowering

these are my fave indicas mostly

on thursday i transplant the sativas in in coco...veg em for week [or two] then flower 9 over 4 x 4 ft area

thfan over clones.jpg clones under grid day one.jpg ose and all the other seedlings i started are under the 15 strip 600w panel on flood and drain
 
would these be any use in a cab as side lighting for sog grows, having qb's as main light sources.
If so how close can these be to the plants?.

they have the same chips in them i am using them for veg and flower...i am using a fan attached to each..

they are 250 w and 6" x 22" 48 v dc

how close depends on what wattage you are using and what the particular plants want..it is subjective

i had to raise mine for two particular sativas while the other two were fine..less is more from what i am gathering
 
Nice builds!
The girls seems to love it!
Do you also know the voltage bins of your 561cS6 diodes? Is it AZ, A1 or AY (top bin). There is a 20mV gap at nom. current(65mA) between AY and A1, which could be one of the reasons for the slightly different results.
 
they were A1..thanksty mex inflower.jpgth mex in flower 1.jpg

here are a couple flower pics of my recenty mexican test

here is a group shot from last week


pre flower.jpg


the smaller ones not ahown are large enough to transplant from 27 per 4 x 4 to 9 per

they were the indicas and are very dense branchy and squat../ i look forward to seeing themstretch under 12/12 ...
 
here are the transplants i posted a week ago..

they had been over watered indica transplants 1.jpg and not enough cal/mag

getting all these mini systems ready along with cloning and building led grids slowed me down on getting my new nutrient regimen in order..which i have never really completely done
i should have it more together tomorrow..if the ratio's etc work i will post them..
calcium nitrate and magnesium nitrate along with some silicon

then i willsee what n-p-k ratio i do..i have mono potassium phosphate but we willsee if ihavev
the guts to try to fit that in

i would like to do organic as long as its hydroponic so it seems if i really want to do that

will have to go aquaponic since i donnot feel pbp is organic and do not do jug nutes anymore

it would take more than a few fish..hahaha

anyway..ihave kelp, dry soluable fulvic and amino acids... starting to use that as foliar

group flower from afar .jpg flowering starting under 6 x 22 panels..when i dial in my new nutrient ratio's..i expect better things but i am dang happy so far

not pushing the light..i really think less may be more..i see that this light can do 5 x 5 ft ie.25 sq ft mex cola in flower.jpg

Select Mexican sativa

Gotta change nutes to the proper ratio

Why do I spray them then take a photo
(Rhetorical)?

Might be a bit over kill as the theroy is about light spred etc however as the leds are so cheep you could put alot more on a pcb and still get a good heat distribution
there like $0.055 an led after all

The thing is you have to find a reputable company, having done business in China I can assure you that most companies, especially the ones I dealt with had a Knack of not giving you what you asked for. If its cheap its cheap for a reason and would have me questioning the authenticity of the part and whether it was a genuine Samsung Diode. Cheap parts tend to offer terrible performance/longevity so beware of the false economy that is Cheapness lol!
 
@OMS gotta say this type of design makes sense as far as LED... no scrub that as far as horticultural lighting is concerned, having tested similar lighting layout/configuration back in the day using 4ft x 8 Phillips TLD 36w/840 tubes I always found performance was much better vs 600w HID, due to the even distribution of light across the canopy and the Fact that you could place the tubes within touching distance of the plants... With the advent of LED strips, QB's and your panels here this type of layout is/was a no brainer... Good luck on your venture;)
