"High Lights" - high powered, CRI95 flowering boards made in Australia

[Frank Cannon]

Yip I hear ya, seriously tho as my cryptic shit gets me in trouble a bit, considering temps, this is looking to be as good as the QB96s in optimum conds..so I am more than happy with em!!

Hi everyone. I'm in the High Lights club for some weeks now.
I promised some pictures, so its time to post some. I would rather not yet, this is not in ideal grow at all, also around you guys i feel pretty noob and the setup is just missing some finishing touches.
The panels dont hang straight since the power wires are too sturdy. It just does not look that nice. I'll have to take away some of the isolation, but that will get done after this grow, since it has magnesium inside. Don't want that on my plants
But I have to show some buds. While this Grow was really hard on them, starting in a 2x2 tent with too long veg phase (meaning they got too big), and got moved twice during the building of my new grow space (Ikea Pax closet), they also had too less light for weeks and the big plants won the light fight over the weaker ones. Oh and they also had thripse, which I could fight rather fast, still the damage they done grew especially when on limit with the new lights.
BUT
I have some really big buds for that

One part of the grow space:

The last days it was too hot here, the leaves hang more than usual. I'm glad it's getting better tomorrow.

The buds:

They probalby need around a week more.

The other side with the weak ones. Don't judge me by them, but they may are interessting anyway regarding the lights. I also want to note, I got them as cuttlings, where as the strong ones were from seeds. I did not get them super healthy.

It looks sad. Like this:

(thumbnails are enough ). It got harvested yesterday, while the hairs were already all orange, the trichromes just started turning brown (about 15%). They are very very compact buds, so I got still something to smoke

The interessting part is the burn it got. This plant didn't receive enough light from week 1-6 in flowering (panel was too weak for the bigger space and it got covered up from the bigger plants). The difference was already big so there was not much I could do.
After I got the High Lights, I wanted to burn them. Go full, no regrets (well I could not lose much here anyway).
That means going up from a space with 120w light (F Series) and alot covered from other plants, to 240w and nothing in the way anymore. And pretty close (top bud was like 10cm away)

Does it look different from heat or usual light burn? For me it kinda does, it could be rather a "sunburn" from the UV lights, but I didn't experience heat or light burn yet myself. But it did not start at the tips of the leaves, rather in the middle, getting crunchy pretty fast.
A side note: the very tip of the leaves showed some burn signs on all plants - specially the bigger ones. That for me was light burn, but in a amount that was fine. They all had pretty dark green leaves, as they had too much nutrients because they had too little light, but it started to decrease with the new lights. The burned tips stayed the same, so I was not worried.
I also noticed that the strong plants also got burn signs, mostly only on the part of the leaves that got damaged by the thripse earlier. These parts just weren't strong enough.


Overall it looks amazing. The amount of trichromes are really good. There are some concentrated areas where I was really scared that I got powdery mildew, but with help of a microscope I could verify that its all trichromes.
The smell is already super strong, even from the weak ones.

I'm rally looking forward for the next grow with more ideal setup from beginning.

No, that's nutrient burn. Are you growing in coco or soil?

Light burn looks like an even yellowing or "bleaching" of the upper leaves and buds, which will be white right at the tips and work down. You have what I suspect to be a build-up of salts in your medium - in other words, too much nutrient.

But apart from that, I love what you have done with the lights - the way you mounted them - and your buds are looking pretty big and dense too!

On the subject of UV, I have noticed that the High Lights will bleach buds more readily than other LEDs that don't have UV. Even though there is only a small amount of UVA and near-UV in the High Light spectrum, it has higher energy than the other wavelengths, so has the potential to damage your plants if you keep the lights too close or the power too high.

In fact, it is this same stress response by the UV light that causes your plants to produce more oils/terpenes as a defence - which gives them a stronger smell and visibly more trichomes (at least anecdotally in my experience). But it also has the potential to cause cell damage if you overdo it.

We took note of the fact that other LED grow lights that use UV have them on a separate channel, which is usually only turned on for a limited amount of time during the 12/12 lights on/off period. So we decided only a small amount of UVA was needed if the High Lights were to run one channel (one driver) continuously for 12 hours.

Im growing with organic soil (Biobizz), so nutrient burn is not that easy, but maybe because they had a phase with too less light.

Damn I'm getting quite unlucky so short before harvest I just found one suspicious leaf, when inspecting it, I found a bunch of spider mites and traces of powdery mildew. I counted about 10 spider mites on that leaf, but I can't find anywhere else. The powdery mildew are just traces, if I didn't knew how it looks like, I would not see that. Found only 1 other leaf with a few traces so far. And while inspecting a lot of leaves, I found a thripse. Only a single one. Damn. Everything is in such a early stage, I could possibly go a few more days without much damange, and the trichromes could really need that. But 3 threats? I guess I'm gonna have a long night and harvest them a little too early.

Sooooo UV-a didn't completely prevent pests & fungal issues in your indoor grow.....................shocker!

insects that exist under sun light thrive under uv too? omg!

I cant say for sure but it kinda looks like the fade under our most over built light (about 2000 diodes per 1m2). The top leaves went from fading colors to very to super cripsy and dead in very little time and just burned off. It seems to happen to us when light is hitting the leaf from all angles, boards being very near. Not discounting that there

We had some similar burn/crispyness on some top leafs under intense and enveloping light. I think it was associated with the fade, they first went red-purplish then just burnt. Buds stayed fine and got very chunky.

On the subject of insects/bugs....
The Insect Repellent Device.
Has anyone seen these 'anti insect lights?'
Sez the insects just leave the area?
I don't know what the spectrum is or whether they work or what they cost so don't shoot the messenger lol

https://www.metaphase-tech.com/horticultural-lights/insect-repellent-device-24-45/


Lights are placed underneath the plant’s canopy to drive the insects to the top of the leaves.
The light prevents them from laying the eggs beneath… so they leave. Others just leave.
For spidermites and thrip too.

If we can find out the spectrum it could be diy-able

 

[Prawn Connery]

LOL! You'll never here me making that claim. But I will say this: a friend of mine is using a couple of High Lights in conjunction with HPS and recently had an outbreak of whitefly and they all flocked to the HPS and left the LED virtually alone. But that had less to do with the UV and more to do with the heat.

Again, we're only talking small amounts of UVA here - I'm not sure how insects would like continuous UVB.

I don't really get "fade". But then I don't flush.

Exactly that. The top leaves and stronger on the leaves that got hit from both lights. While the buds stayed finde. Do you have some pictures?

 

[Rocket Soul]

Sorry, no pics but ours were the same: top, and exposed to "eneveloping" light from several boarss. I think i saw @Airwalker16 having similar issues.

 

[Prawn Connery]

If you're interested, search for "potassium deficiency" and you'll see leaves similar to yours. Not uncommon in the latter stages of flowering when the plant needs it most. It can either be a deficiency (not enough K), or can be locked out by salt build-up of other nutrients.

[min444]

Thank you for the interessting video. I'll look some more vids from this guy

What does not match the potassium deficiency is that it does not start along the edges of the leaves.

 

[Prawn Connery]

You're right, and the more I look at your photos, the more they look like spider mite damage - all those tiny pin-pricks on the leaves. I'm not sure how bad you had them, but you did mention you'd found some. Were there any mites or webs under the affected leaves?

 

[min444]

It does have similarities with advanced spider mite bites, but the pattern is not as random as with spier mites. Also there are no signs of spider mites, and when it looks like this, the spider mites are that much advanced that a lot should be covered in webs already.
In total I found 2 leaves with spider mites, one was the "suspicious" which had around 10 of them (mostly young and very very small), while harvesting the plant (I still let 1/3 alive) I inspected a lot of leaves with the microscope, and could only find a single additional spider mite. Since then I'm oberving the remaining parts of the plant very closely, but did not found any other so far.

There are some other deficiencies that look similar but they all dont fit. I think the main difference is, its like the dots are adding up (thats why it looks similar to spider mites) and dont grow. I did some research now, and I can't find something that matches.

But it's not that important as it only showed up in the last weeks and didn't seem to have a big impact. Also it's pretty offtopic for your thread

 

[Prawn Connery]

No, that's OK. A couple of pix look like mite damage, a few look like nute burn (which is actually lock-out) and it's all hard to tell unless you're there to see it I guess. Ultimately, the growers who have the problem usually have the best idea what it is themselves, but a few suggestions can't hurt.

Don't worry about going off topic in my thread - anything goes here!

I didn't realise these were a thing, but apparently yellow light insect repellers have been around since the 70s!

I found lots of them when I googled. Even found this video - unfortunately it doesn't explain much:

Well here is a pic from the Highonlife panels, week 7, 2 to go.

Conditions still far from optimal but Or_Gro made me install a dehumidifier so day temps are up 7 to 72F, lights off 53, humidity has dropped 10-15% to around 70%. EC 2.1, pH 6.1, ppfd 950 at 110w per panel at 15" above canopy
