When you run alot of automation, your risk of something fucking up, without you realizing it, starts to skyrocket.

Yesterday afternoon when working on uv testing, i just happened to notice my far red bar was on! Should only be on at beginning of lightsout.

Apparently, the brownout on wednesday shut my analog timers off, and they restarted with a big time gap (not sure how, gotta work on this now). Luckily/?unluckily? only far red was running on them at the moment.

I thought i sensed a slowdown in pistil formation, maybe there was one.

Anyway, lesson hopefully learned (you never know with reefer involved ;) ). Far red back on planned timing.

Cool you are testing the qb's separate from your current lighting behemoth. With those drivers will they be maxed out?

They will be tested as a single, double, triple...up to an octo, all in separate tent w/ grid.....then, early next year, side-by-side smackdown with clones, in two 4x4s: one with the timbers (eight 288s), the other with 96s (same amount to equal 288s in ppfd).

I’ll probably be testing at 120w, 160w, 200w, 230w (max rated 4.2 amps @55v), and prob one level higher (absolute max 6.0 amps).

Lookin forward to this, zeroing in on strains: jack herer, green crack, gg4, and nirvana’s beautiful gsc....sorry bodhi guys, but bodhi no longer selling goji og and sunshine daydream, can’t find much enuff info on other strains i usually look for to make selection decisions, and i hate extra time for sexing regular seeds...

If you are getting the gg4 cut you're really going to like it. Definitely a keeper. I've grown mine out a few times now and have some on deck in case the Dark Helmets turn out overly manly.

Lookin forward to gg4, all of these are firsts for me (i have a strain to do list longer than the bible, probably never regrow a strain).

For the smackdown, I’ll start from seed, make clones, and live with whatever phenos result.

“Overly manly”, as in donkey ds? Lol

Breaking out the uvb meter to test my glasses, 2’ arcadia t5 reptile lights, and 4’ agromax t5 uva-b lights.

So @Randomblame here’s what i got at 18” above tallest mains, which is where my main lights are:

2x 24” arcadia 12%: ~45 uW/cm sq

2x 24” agromax uva-b: ~180

1x 48” agromax uva-b: ~ 440

Think i’ll start with the 2x 24” agromax 15mins beginning and end of lightson, what do you think? Should i switch to 48” at some point?

I was surprised about agromax 2x24” vs 48”. The 2x 24 agromax were used on one other grow during last 2 weeks, but that seems a big uW loss for 1 short use, maybe has to do with fixture?
i love using just the 2ft agro placed up high. thank you for the testing & posting the results.

Hey @Randomblame , haven’t seen you around, hoping everything’s fine for you and yours....

Gonna light up the west coast of US tomorrow...
Yeah, all good. Just a bit busi..

UVB output depends also on reflector.
As far as I know these bulbs need a short burn in time to reach a stable output. At the beginning the poutput can be much higher and the reptile breeders rise their fixtures at least 4" for the first 100h.
The difference between two 24w and one 54w bulb is pretty small I would not expect such a difference. Are the 2 footers mounted in a row and did you meassure between the two bulbs? Or has the 54w bulb another reflector? Hammered reflectors have less intense center readings but better distribution.
Normally I would expect to get 440μW at 1ft and 170μW at 2ft measured in the center or the bulb no matter if its the 1 or 2ft bulb. The 4ft bulb is only two times as long and the 6w more close only the gap one would get between two 2ft bulbs so its not really more intense.
Also the Arcadia readings are low compared to the numbers in the pdf I've posted earlier. You should get 45μW/cm² without and 80-120μW/cm² with reflector depending on surface structure of the reflector.
Really strange!!

Plants look a bit tired but thats normal when you start using it that late. Also 180μW is pretty strong and I would expect a few burned tipps and wilting leaves with a few hours. A plant in veg would completely recover without burnings on the new leaves but for this ladies its too late. But I don't think that this cause any issues. Lots of the leaves anyway die earlier or later. As long as they cause no bud rot its all good.
How much UVB they get currently and for how long?
I do not necessarily feel like there are a lot more trichomes maybe 20% or so but their "heads" will definitely get bigger than usual. I have a little cam adapter with 60x magnification I've found on ebay. Perfect to watch the trichomes color changing..

Here are a few SLH macros around 10days before harvest..
SLH macro's7.png SLH macro's4.png

SLH is definately worth a try. Its really a high yielding strain compared to the Bubba'sGift the difference is amazing. I got 135g of BubbasGift nugs out of 7 cuttings but 405g from 9 SLH cuttings. All without veg and all in the same tent.
BubbasGift, 2x 50g + 15g = 115g.jpg SLH, 5x 50g + 4x 34g = 385g.jpg

Have already prepared something in a liquid for my atomizer. Rosin with liquidizer, 1g : 0,8ml ...

4ft has reflector; 2footers in a single row don’t have reflectors.

I do notice new trichs curling, but not necessarily drying out. Doing 15 mins each, start and end of lights on, planning to switch to 4 footer this weekend, then add 15 min to 2nd hour, then after a few days 15 mins to 2nd hour from end of lightson, then 15 mins to 3rd hour, and so on, until 15 min/hr all lightson or until damage visible.

I use a carson zorb (usb):

Okay, than the intensity difference is normal. A reflector almost doubles the UVB output and I wish the Agromax would have such a build-in reflector like the flowerpower bulbs. One half of the bulb is alli coated from inside and such a coating is even more efficient like an external reflector. Without additional reflector the mounting area is rather small( only bulb diameter) and it would be much easier to integrate them next to LED strips or boards without disturbing their light radiation. My reflector is 80mm wide but I need another 20mm on each side to avoid light loss from LED's.
The only thing is, its a 120° reflector and you can not change the radiation angle and loose some UVB on the walls.

I think in a few days the girls are used enough to UVB and you can increase a little faster. I've used 6h from the 2nd week and when the 45μW/cm² of the new Arcadia is measured without reflector it fits exact in the range of the arcadia datasheet(112h old bare bulb, 38μW at 45cm/18" and 47μW at 40cm/16") so my assumption of 150-200μW/cm² at 30cm/12" with reflector should be correct and I've used it the whole day.
12h with 200 would be the same like 6h with 400. But this not means you should switch immediately to the 54w bulb with reflector. 180μW/cm² is for sure compatible when the first week is done because I've used 200 already with no damage but I'm not sure with twice as much. On the other hand, I've not tried it yet and a try with 400 would be interesting for me cause I already have a few Agromax here which I want to test with the next sativa run.

I’ve been playing with the idea of getting some flowerpower bulbs. They say that 2 of their 4ft fixture covers 8x8?
