Extreme Flowering Under Pair of Timber 48SAMS

Looking forward to following the UV setup and how ya do it

Looking good bro!
I have a feeling those buds are going to be insane lol
I have been busy since I did my big defoliation. I will have time tonight to do some more and take some pics!
I started training my seedlings the other day too. I decide to top and leave it so it has 4 mains I left the node that’s right below the manifold node. If that makes sense lol.

Looking forward to your pics or a rasta music video.

If it’s how i think, they call that an uncleben.

Nice to see you over here, too.

Anyone have a good uva-b meter candidate?

Ya I did come across that uncle Ben.
Haven’t tried it before. I might manifold some still and do uncleben on some. Idk lol I just know, for me, not training sucks if you don’t have a scrog.

I look at it as 2 separate things: plumbing system and training, sometimes plumbing system is so good you don’t need to do much training.

I once planned on doing manifold vs uncleben, but fell in live with manifold first.

Do it, i still wanna see a sidebyside.

Solarmeter UVB 6.2 is currently the best device because the sensor is more weighted on the area below 300nm. Most other device can either not read this area or are weighted to the 300-320nm range.
So for C. (and also for reptiles) the area below 300nm is the most interesting (UVR8 protein, vitamin D3).
They have a lot of different UV meters; the Solarmeter 6.5 for instance can measure UVB and/or UVA and costs the same.

Thanks MC. Nice presentation.

I’ve seen the various versions of that meter, but surprisingly couldn’t find many independent reviews of it and competitors. One fault with these is that the sensor is in the meter rather than on a cable, which increaaes potential operator exposure risk.

Since i didn’t know quality of company, i was leaning toward apogee’s sensor (since i have their well-respected ppfd sensor), but with RB’s endorsement, i like the less expensive price. Ordered.

I'd strip the hell out of those, but I tend to do a little bit at a time and that doesn't look feasible with the access to the back you have. Can you remove the tent walls and get around the sides and back?

Day 33 of ?84?: Girls not rejecting UVa-b, at least yet; faint hints of a skunk in the growroom. After elevating the “diesels” more airflow off ~65F floor has forced me to crank heater temps to maintain 81-83F airtemp in tent - dynamic systems...

Ppfd ~1050 on highest tips under each fixture, all other controlled variables in range.

Plan on upping begin-/end-ofday uv duration 15 mins each tomorrow. Cautiously searching for burn point.

Gettin thick in there, have to think about defol aporoach now that they’re in mid-flower. Comments welcomed.

my only conundrum with leds & the higher temp/calcium issue is that i learned that the most volatile terps evaporate at 70-73*, and if you can smell it your losing it. i still somewhat believe in @RM3 mantra of "happy plants dont stink".

Thx for the moral support, i always say it takes big ones to be a good defol’er. Just momentary lapse of reason...

No prob gettin in there, the whole 5’ panel unzips, and i unzip front and 2 sides daily. After working in a cab, feels like grower heaven.

Good point, when i get lotsabigasscolas out of my system, i will be focused on terpene quality. Can’t help myself at the moment. Rite of passage thingy, i guess.

I don't think there is a trade off running led at higher temp. The reason you can run a higher room temp is that the IR isn't going crazy and warming the leaf surface. I wonder what the difference would be in actual leaf temp from an optimized led grow and an optimized conventional grow. My nonscientific gut is betting they'd be about the same. There has to be someone whos tested that......

Man, i cant wait for canadian (maybe even some bold calif/or/wa/co universities - sched I probs in us) researchers to get on all this basic research! ‘

Such a big market opportunity, i expect lotsa research grant competition.

In this grow, leaf temps are running ~ air temp. In my farm field W diff crop, exposed leaves can be 30+ F higher on a sunny summer day, depending on temp, rh, wind, & stomate condition.

Exactly what I mean. My theory is that we'll get the best flavors by growing the healthiest plants. Curing, on the other hand, once those smells leave they are gone! I keep it at 66f and am thinking to go colder.

keeping rh in balance at lower temps is the challenge
