DIY led grow

[Positivity]

Smallest plant I've grown in a while, just a gallon of soil, didn't even feed her the whole time. Illuminati gluttony...quick strain, few weeks ahead of goji.



gsc getting a slow and steady veg at 330ma 72v 3590 5k

Bonjour
How many vegg for the gsc...and what size of plant and pot...5000ºK look very nice for vegg...but I don't know yet if it will be 5000º or 6500ºk?because of DD bin!

Really don't know, don't keep a calendar or anything.
At least a month from clone. Gsc is my toughest plant to clone, always slow and small roots out of the cloner. Surprised she grew out of her bad start

1g smart pot.

Never used 6k... Probably similar I'd guess. Maybe tighter nodes.... I'm happy with 5k for now. Let someone else test that..lol

Bonjour
I fact RS do it...6500ºk DD...very efficient...66%@1400mA or 700mA for 72v...he use it at 500mA and less and get 72%...a lot...he said he's going to try to vegg under...but not a lot of news from him since...! (He's about to do something...lol!)
I will ask him!

Check out this White Widow (freebie) that's growing under my DIY.


The bud growth is congested as hell. Since its my first experience with WW i didnt know what to expect. I looked around at a few grows and the other plants were stretched out with the expected, common type of branching This plant barely stretched at all whilst developing the tightest rocket ship shape. Today (day28 11/13) i decided to tie her down and open up the shape a little bit. .

This plant looked like a normal sat/ind while it was vegging under CFL and then it got all tight and congested when placed under the cxb/v29. Anyone have experience with WW or seen plants get tight under cobs?

kinda funny you say white widow. I got 2 paradise fem ww freebies vegging right now...never grown ww before either.

theres been a few grows with short stout growth from 3k and even 2700k..bbspills? sds plants were pretty bushy too..

Think its more dependent on ambient temps, genetics..

 

[testiclees]

my lay out has 4x 3500 and 4x 4k.
im looking forward to watching this plant mature. if those budsites fill in, (6weeks to go) and frost up it will be good start to the newyear.
@Positivity i have heard that the strain in general is bushy,not a big plant. This plant is kinda like a witches broom type of thing.

@testiclees ...cool, i'll put pic up when they are flowering. mine are still babies..



unrelated random vids

dedicated to my $800 el cheepos that never worked from day 1. and any other related junk..

kinda miss a girl i went out with once..she loved nsync. young n dumb

Bonjour
I grew a few WW and it is always dark green and bushy...but not as yours!
If you have only one cob under one plant it is possible to put the plant very close and to control a bit the stretching by "crushing" the plant with light...that is what happened with mine...I don't have a lot of height 4.5 fett so I tried to keep it as low as possible and it is easier with cob!
@testiclees is it 4000ºk db?...I want to try those with 3500ºk cd!...my next panel!

3500 cxb cd, 4000 vero 29 v1
i wonderede if i was crushing them with light but other plants have grown towards and inti the light. However this plant shows irradiance damage more so than any other ive grown under this rig. it is at about 18-20" heightt

Testament to just how much light is coming from these setups. Also I believe it's strain dependant of course on light requirements. Skinny leaved require more PPF vs fatter leaved requiring less. Just my opinion no science to back it up of course.

That's the first time I've heard the term "irradiance damage" used, but it's a useful term. I have one pair of cob lights with lenses and I find their light intense enough that it doesn't quite bleach the leaves, but it does seem to cause them to fade... like something painted left in the sun too long. The plant I currently have in that space is in flower, but instead of letting it get closer to the light I've been raising the light steadily, looking for a sweet spot and hoping to ease the intensity.

I get that sometimes, my observations tell me that I am not providing enough general plant health, and in my case seems to be limited by media volume. (ie need larger net pots)

 

[testiclees]

Ill post a pic of the damage that i am referring to. Its not an obvious bleaching type reaction more like rusty necrotic patches. I have tested the light at varying heights with different plants, close to 20"'seems about right for a general all purpose height.

Maybe it could be a deficiency or an issue with foliars but aside from the leaf damage plant health and development seems robust.

sounds kind of like a slight mag deficiency to me....

 

[testiclees]

Thanks man. I'll post that pic as soon as i get back to flower room. I was associating the witches broom type growth with the light so maybe i automatically assumed the leaf issue was light/heat related.

A couple of other details: the damage is on upper leaves with the high exposure to the lamp. I start out with a soil test and then broadcast amendments to balance minerals. This plant however was placed into a hole I cut out of a pot where a plant had recently been harvested. The pot was re amended and topped off with EWC and alfalfa straw. It's 7 gal pot

I get that sometimes, my observations tell me that I am not providing enough general plant health, and in my case seems to be limited by media volume. (ie need larger net pots)

I'm doing too many experiments at once, and I have four plants, all different strains, so there's nothing scientific about my observations... I need to find one strain I like and stick with it for a while.

One thing that made me think its the light is that my canopy is pretty even, and the leaves in the direct light are lighter a bit yellower (not as deep a green) in color than the ones lower in the canopy. Maybe that's always the case and I never noticed it before, but its very pronounced with this one. (and in case its not obvious, I am talking about when a leaf from each area is trimmed and viewed in the same light, not how lower leaves look when seen in shadow...)

 

[testiclees]

@Humanrob the hypothesis about the wider leaves and thinner leaves and their optimal light requirements/tolerances might make sense in my case. This is the first indica leaning strain Ive grown with this light.

Please check out the pics. Leaves that are low and inside on the plant look fine while the older more exposed leaves are beat up some.

 

[Humanrob]

@testiclees -- that is interesting, I wish I knew more and could suggest something.

I'm growing sativia dominant hybrids -- my patient's preference. The plant I was referring to is a Bruce Banner #3 which I have alone in a 2x2.5 space under two Optic 120's.

This grow has been another odd one. I had three in my tent (2x4) under my DIY/COB light, but after 4 weeks decided it was too crowded so I was going to toss the weakest one... but I couldn't bring myself to kill it, even though it wasn't doing well it was a GG#4. So I converted my veg rack into a flower space, and put the only extra light I could find in there -- an old 3w 96 Mars Reflector that I used once when I was first investigating LEDs. Under that light, the GG's leaves and stems corrected in a matter of days, and it's currently the healthiest looking plant of the bunch (the other two in the tent are a Sour Diesel and a J1).

COBs are demanding lights. I've only got a handful of grows under my belt so I'm trying to rise to the occasion. So far the best thing I've done, is when it doubt, raise them up. It seems to ease things up and give me more time to figure out what I need to do next. Eventually I'll dial in everything else, and I'll be able to leverage the lights better.
