Well, I had those markings on a plant and, whatever it's called, it did negatively affect the plant. Half of the leave would develop normally and the other half was only say 50%. Pretty much like visible in this plant. More importantly, the same happened to the buds (partly fully and partly half developed). Which in the end cost about 25% of it's yield.

Although it looks less severe in this case. Only a few leaves seem to have actual problems apart from the discoloration.

I've also seen these markings on a small plant (from the same batch of seeds) and later they were gone in the new growth.

I had seen this before in a critical mass automatic I grew. The yield was fair, 2-3oz. I don't really weigh my products accurately because I just use a kitchen scale. Its all personal stash. But that's aside the point Lol. Im interested in seeing what he/she does regardless. The autopounder was honestly a garbage yield but very dank. This cross is showing leaves resembling the querkle father but seemingly mutated ... I do believe in cannabis mutations being pretty common but I dont have enough hands on experience with breeding/chucking to back up this.

Nah I'm not a commercial grower, I'd say I pull 3ounces dry from her in 6litres of coco so pretty average. I've put mine in the leaf variegation category.
I've messed around with the feed to see if I can correct it and it seems a lighter feed has helped a lil. I thought I read TMV spreads to other plants?

She's a lil slow in veg but the crazy tight nugs that stink of citrus diesel mean Im not chucking it until I find a replacement

Sometimes, weird is wonderful

drivers and UVa chips have arrived.
Post up the characteristic curve of these chips momentarily as i need to test them. they were labelled as generic and i was given no datasheet other than a max current of 1A and 3.8v max driving warning.
i did not feel the need to get a meanwell driver for these chips since the UVa will only be on for 15 minutes a day and the far/photo red for 15 min twice a day. Anyway, the driver's labelng suggests they are pretty efficient and they were purchased from a commercial seller.

basic drift of what i saw using the 365nm beads. again, i will be using them at a 600mA CC state

Damn... What current are you running the strips at? Do they provide the PhoTons?

Lmao they provide the tons! Im 95% certain they are using lm561c diodes. the drivers sit at or above 85% and you can select 4current options. .335a (45.5v), .39a(46v), .45a (46.5v), and .5 a (47v)option. The strips are rated for .9a 49v max and are staying at a very low temperature, you can touch the leds with your hand even after it has been on for hours

eyderbuddy · Jul 17, 2017

So they provide the Tons, and don't require 15-20 dollar heatsinks per cob? it makes me doubt COBs. And i'm talking about the introductory price ofc COBs have an application.

I spent 45$ on the 2" u channel and fixed them together with machine screws. So, if you have a saw capable of cutting aluminum accurately and a drill press you can DIY a very nice panel somewhat easily. I would likely have used a large slate heatsink from hlg had I not been feeling handy.

My strips order has already been shipped

I'm going to mount them into aluminum channels and use them to grow my greens. Going to use the cobs for high PPFD applications.

Having a tough time reflowing solder. Hanging my hat on this route of far red and photo red. It looks like I'm going to go for the cheap Chinese 3w emmiters already fixed to pcb. Efficiency really shouldn't be an issue for such a minuscule amount of use per day. I mean 15 minutes on and 15 minutes off ? Eh ill make due with cost effective parts for now. Smdh.

iHearAll · Jul 17, 2017

So I'm only working during lights out. I posted this in another thread about UV. Here is what I have come up with for a mixed spectrum point source-ish UVA emitter. They aren't fixed to the panel yet but I'm thinking this is a fair compromise of real estate.

Making the assumption on the diode used in he TCL strips as lm561c. I pulled the datasheet to check out the IR wing on the 3000k and 4000k.

They look like the don't need the photo red 660nm part of the initiator I had planned. So I will skip out on that and just purchase ten 730nm 1 watt diodes prefabbed to pcb and call it a day. I got so frustrated working with DIY reflow... Goodluck to anyone trying that nonsense with the 1w cree leds. Those are too small for me.

Fuck that! I'm impressed you gave it a go though - my fingers and eyes would never be up to that.

Are you still running these really softly or have you bumped up to .5A?

The cree diodes were recommended to be driven at .35ma so I purchased a .3a driver. Now I'm looking at more .35a diodes so I can make use ofthis driver. Otherwise yea I would probably have gotten .7a diodes and another driver.

Edit, in case I misread and you're referring to the UV, the picture is the intensity I will be using. Theyre at .6a

iHearAll · Jul 18, 2017

Wellp the mishaps come in waves. Turns out that although I was told the UV driver I purchased would be capable of powering 30 chips. Big nope. Lights sit there and blink. Had to buy another. But! Now I can power half the panel then the other half at separate times I guess

dopeonarope · Jul 18, 2017

Might be able to find some way to try and mimic sunrise/sunset like aquarium lighting if you can control half your UV at a time? I like that you're staying positive despite the odd mishap - good learning experience

Can you elaborate? Sounds cool

iHearAll · Jul 18, 2017

Panel minus three leds. I simply shorted three with a wire to reduce the voltage of the circuit. Posted in a UV thread earlier.

I'll look for some technical info after work as this is just anecdotal and I don't have one myself but: I've seen quite a few aquarium setups that gradually ramp up brightness from one side to the other to simulate sunrise and then at night there is gradual dimming from the opposite side to simulate sunset. I know this is a big help with coral - would be interesting to see what plants think of it too.

You could bring the TCI strips into play as well with the arduino controller mentioned earlier in this thread and get them dimming too I think? You'd need some kind of controller at any rate to attempt this with the UV alone so if you went this route, I'd go all in and get the strips happening too

Two timers could allow one to turn a side on, then both, then the other side. Might be cool. I have read threads where members suggest that their plants grow toward the UV light over their whites. Pretty cool imo
