All COB Users - Lettuce Grow Challenge!!

[SSGrower]

i have no idea what you mean

my brother is growimg letuce and has used burples too..the organic restaurants rave about the texture and taste....

maybe its not the light my friend..

Sorry if any of what I said was misinterpreted, it was meant to be a compliment. Trying to say that based on the limited info it looks like you (OMS) have a better handle on how to optimize led use.

Speaking of environment, an issue I had with some of the 60w cob butterhead did stunt but it was more of a trapping of new growth because the outer leaves were stuck to each other. You can see it a little on the one I call hydro (vermeculite and coco) in an earlier post. IMO if this was light related it was an issue of too intense, but I lean towards it being environmental. I would certainly appreciate any insight you, or the other gardeners who are posting here (who are obviously more skiled than I), have.

hi thanks for the reply

i wish ihad ahandle on things..we are just testing different led bars/panes in burples and whites

e hvesome cobsbuilt but have not used for sald yet..

ee have found that white 3500 k self powered led tubes work pretty good though you have to be close..

even cheap crap ch9ijna panrls work pretty good..i like tgeled tubes bes6 so far..but we do have a difinitive winner anywhere

the tubes win on nice colour, good price, and are effective

they are cheap and handy ..we hope to hook up some nichia cobs or veri b18's but have not done it..

Another test going down
First pic (red leaves) Vero 18 3500K
Secod pic Horti Blue
Same high quality pelletized REX lettuce seeds. These are not supposed to be anything other than straight green!



Ran into some tip burn issues on my last MH lettuce but trying a different nutrient and grow method so need to determine which is the factor

Greens/micro are creeping up and cannabis has dropped to $112 a ft..................lol.............red veined sorrel, 8yr cut/recut perennial that brings in the $$$$$..........haha, not quitting my day job yet

Monsanto/Bayer merger is looking like a go, pitchforks ready

 

[OLD MOTHER SATIVA]

the self powered led tubes are doing a great job..less wattage per4 x 4 ft area ..cheap..no burple

only thing you have to do is keep em close to the canopy..i think we are using 120 -160 w per 4 x 4

You must take issue with #3? lol

"3. Farming indoors is far more productive than outdoor fields."

more months of production..........at a cost

122 lm/w 3500 k cct 20 w..4ft selfpowered

122 lm/w 3500 k cct 20 w..4ft selfpowered

Can you share with us some photo's of the growth under these?

eventually..but the setup is not here..they are growing as good as anything we have used..it will happen

 

[OLD MOTHER SATIVA]

led tube 122 lm/w 3500 k cct 20 w..4ft self powered

8 per 4 x 4 = 160 w

Gave up on lettuce growing under led
Here is some Lavender Mint i had under 4000K 90 CRI Citi 1818

Ok, what do you cob junkies have to say for yourselves?
To call a cob led a "complete" light diet for plants is clearly a false statement.
Just look at this pathetic result happening with the Vero 18 on the left. Hortilux Blue MH on the right (first pic)

I'd say it was the grower. @OLD MOTHER SATIVA 's grow doesn't look like that, either do studies done with white LEDs or red and blue LEDs (talk about an incomplete light source).

Purple where purple shouldn't be means the plant is producing anthocynanin, a pigment thought to protect against too much light. It would explain such a sad fucked up little plant, anyway. I mean, that is extremely unhappy looking, and blaming COBs doesn't make sense.

Please prove me wrong with photo documentation of some lettuce grown by yourself under cobs.
Are you saying my photo's and eyes with what I see in person are lying to me? lol

If vero18 at 16" from canopy is "too much light" there is no way cobs will work in a vertical rack system

..food for plants cames from the fish..our whites/blues /reds led bars are growing the greens pretty good too..but are higher wattage and cost a lot more than the the tubes..we do wanna try cobs raised higher for lettuce/micro greens etc
