Have you noticed any differences between the lights in how the plants reacted to the topping and training? Did plants under 1 light seem to “recover” faster then the other? Initial thoughts regarding each light?

Been looking into either of these set ups to Samsung strips

Day 4 of flower: Leaves enlarging and greening up, tops starting to stack nodes, should see some vertical growth soon. All controlled variables inrange.

All 8 plants were vegged and trained under the 96 elites. They have only been separated under the two diff lights for a week. No signif diffs.

I don’t know anything about the strips, so can’t compare.

Interested to see how it turns out. The strips are just another option but the two your running here seem to be the most popular

We’ll get a first useful comparative reading after stretch, maybe even before...

Yeah, i know what f strips are, just not the technical or grow camparisons...don’t they have same diodes as 288’s?...if so, same soectra, and at same intensity coverage, should be similar to 288s...

I believe they use the same LM561C diode. It I’m not 100% certain. I supposed the difference would be even greater light spread with strips? But I’m no expert at all

288 v1 would be that diode, v2 would be 301b...intensity spread could be matched, so for same intensity, 288s and f-strips should give similar results.

After stretch in this grow, 288s will not be similar to f strips, as supplemental reds will be turned on, changing their spectrum...but next few weeks my 288s should be representative of f strips w similar intensity spread.

Who says defol doesn’t work?

Obviously high photosynthesis rate, judging from recovery after having 90-95% leaves removed 3 days ago...Every bit of this growth is going to the plant tips...at a time when the bud primordia are starting to develop there...can’t wait to see what comes of it...

I have a good news for you.
You don't need exactly 285nm it works with 290-300nm too. It only takes longer to cause the same reaction. For this reason it works with the reptile bulbs otherwise they would have no effect.

1h with 150μW/cm² is the same like 10h with only 15μW/cm². More energy comsuming, yes, but you can still add it and with reptile bulbs you don't have to worry about burnings or stress. My plants always loved the blueish Arcadia bulb spectrum and have prayed harder than I've ever seen it before without showing signs of stress.
Even with 8-10" from the tops and 10h the day not a single issue worth to mention besides a little heatstress. But it was really only a tiny little bit curling on the leaf margins of the highest leaf pair, nothin to worry about. And with your usually used intensity you use anyway more distance so IMO there is absolute no reason why you shouldn't use them.
Believe me, the effect is the same. It only takes more electricity.
@Randomblame,

Tested my 4’ Arcadia 14% uvb, in my growbright nano reflector fixture. Like you said, at 12” getting 75-100μW/cm² for a 2’x4’ footprint.

No prob in the 6x96 tent, plenty of room above, but major prob to hang from above in 8x288 ....

After some noodling tho, i tested at 45 degree angle on side of tent at 12”, almost spot on 75μW/cm² across 2’x4’ area from side of tent.

So, my plan would be to mount them this way on both left and right sides of each tent, w/o blocking main or supplemental lights, and ramp to 8hrs/day, for 600μW/cm²/day.

I’d start beginning next week (wk2 of flower).

Whaddaya think? What start duration and ramp to 8hrs/day would you suggest?

Day 5 of flower: Seems they are liking high intensity, heat, rh, co2... gonna boost nutes tomorrow, and add uva/b monday.

By tuesday, a week after major defol, should be back to same foliage level as day before defol, with all the growth at the main/lateral tips, maximizing budsite potential.

Starting to see hints of stretchation...

Care to share a picture of your journals? I assume your a meticulous note taker so interested to see what and how you log things
You’re lookin at the extent of my journalizing.

All my effort, as far, as growing reefer, goes to researching controllable variables and their appropriate levels, and actually putting that theory into practice...

pictures are my journal...

Fuck no, i already spend at least 3 hours/day working on the 4 tents....

I actually have two businesses and a life, too...Lol
Ah yeah. That whole work and life thing.

I do also forget you effectively have 16(?) or so reservoirs. I just have to jot down the stats from one or two guardian monitors once a day.

I do find being able to watch for trends over time valuable, but I get where you're coming from.

Taking notes is a good thing, for some people.... for me, my notes are pics...i review them and make decisions based on them...they contain more data than i could ever notate...course, i have to think about what i want the pics to contain, so i can go back and review...

Believe me, i keep track of what’s going on, what works and doesn’t....just have learned that data packed pics and my memory are more efficient than some cumbersome journalizing process...

My approach is proactive: i set targets (which is really the accumulation of what i have learned), watch for response, and make adjustments (ie update targets); taking meticulous, often useless notes, imo, is more of a reactive, bureaucratic process...

But everyone should do what works best for themselves...

I keep reading comments from people saying these white leds are speeding up their grows vs published flowering times.

I just don’t see it. If anything, i think grows are longer, w resulting bigger colas. Maybe it’s just me and the supplemental lights i use.

But my experience is that the plants go thru two distinct pistil flushes, then continue with a 3rd smaller but extended pistil flush.

These mom’s are 8-weekers, now finishing up week 9 with ongoing 3rd flush of pistils and clear to slightly milky trichs...and yes, i have a good usb microscope, and do extensive sampling...

Exactly how I do it too, also adding a few things to my phone calendar like > clones into cloner, flipped to 12/12 ect. Then I can cross reference with the pictures I took on that day.
