Appreciate the answer here but those aren't my plants haha. So basically you're saying this is the result of keeping the plant too close to the light - I could buy that. I fox tailed the shit out of some buds a while back due to light intensity and they looked weird as hell.

A plant's spectral response range is from 400 to 700 nm which is represented as PAR. PPF is photosynthetic photon flux and PPF measures the total amount of PAR that is produced by a lighting system (/second). PAR = photosynthetically active radiation; it's the photons (the light energy)...

@2Hearts Talk is cheap indeed - so what is it that's going on here? All I can muster up are research papers trying to exploit this mutation in cannabis and then dozens of other photos and threads that look just like the OP's photo all anecdotally claiming to exhibit the very mutation.

It literally all matters though, some things just matter less and some things just matter more. Will a mixed spectrum LED grow dope plants (Black Dog, Kind, etc)? Yes absolutely. So if you as a consumer want to shell out more money to buy a light that has lower PAR output (and if you don't...

Right but if you listen to all of what Bruce is saying, the first thing he says there is that an ideal spectrum matches the sun - the sun's spectrum has oodles of green. The second thing he says is that adding green led's is inefficient but we're not adding monochromatic leds - white led's are...

The Black Dog Phytomax-2 600 pulls 630w from the wall and has a total output 961 μMol/s ppf, the HLG 550 pulls 480w from the wall and has a total output of 1178.05 μMol/s ppf and you're worried about the the HLG "wasting energy" from green light emitted? Breh. At the end of the day, PAR...

Makes sense with the bud being so dense.

Your tent doesn't have the larger ports up high? That's strange to me - in every tent I have had, the largest ports have always been up top. Oh i see, it's an air con exhaust you're venting out of the unit itself. Well if you need an air con, I guess you have no choice.

Interesting, looks like you got a polyploidy mutation. Look it up - wild stuff. Apparently labs are trying to figure this out bc you get increases in potency (potentially) and obviously size. Don't toss it!

Looks like loads of wasted grow space from that (6"?) duct and dehumidifier - is it possible to exhaust from the top (assuming that's an exhaust) and weave over the dehumidifier?

This is from the Samsung H-Influx datasheet. The F series datasheet doesn't have this added excerpt but consider that the LT-F564B Nominal Tc is 65*C and that the intended application for each of these linear strips is identical and I think you get what I'm saying.

No worries man, I have a mangled up strip that was a casualty of sleep walking. :)

The data sheets say 18awg for the one pin poke in, same as for the h-influx I have now but I just stripped a 14awg wire to test fit this for you and it fit just fine, barely but very secure. YMMV

Idk man I ran 4 LT-F564B's under nominal (1050mAh) using 2" HSUSA heatsinks and they got plenty hot enough for me to think some type of thermal material is required, especially considering they are epoxy pcb's. I have H-Influx now which have an aluminum PCB and ran them at 750mAh for some...

Direction and guidance was requested and is being given, don't be salty.

Or what I did and use the 3500k in conjunction with HLG qb11 (or qb18 for 4ft) strips in 660nm

Thanks and thanks. Strain is T.H. Seeds French Cookies. Here's the thread https://rollitup.org/t/1st-waterfarm-french-cookies-diy-led-2x2ish.1011008/#post-15484141

l06's (h-influx, lm301b) in 3500k are avail at arrow for $10 ea, in 3000k they also avail at $15 ea, and 4k for $21 ea. It's the l09 that seems out of stock, but I prefer the l06's anyway since they fit perfectly on the 1" Heatsink USA extrusions.

I'm doing my first run with a Waterfarm rn and that is my biggest gripe - res isn't large enough so the feedings are basically continual at this stage (I think I'm abt a week and a half behind you). Mine isn't even as thirsty as yours (she's a bit smaller too, smaller tent). I've been keeping...

@THC-CK your meter may also just be using the higher conversion factor for ppm, just putting that out there.
