Yes, and with green light. Green photons are absorbed by interacting chl-b molecules which are only present in PSII. You may know the sub-canopy spec largely devoid of blue and red. Here, GL drives PSII and FRL PSI, since FRL is more prelavent the PSII enlarges to increase its light-harvesting...

A decent state cannot, under the pretext of "self-defense" commit an outrageous number of warcrimes and atrocities no matter how horrible the attacks on the 7th were. The Israeli politics is currently dominated by a racistic and fascistoid agenda intent to exacerbate the roots of the problems...

It's just that plants build these compounds in responds to an influx of stressing photon wavelengths, BUT that doesn't mean the stems, leaves etc are going to change their respective colors. That is mostly due to a shift in the interior biosynthetic pathways in case of P-def etc

This is something that I suspect of being responsible for when HPS growers report higher resin/quality when adding UVA/UVB fluoros fixtures. HPS just lacks alot of blue, and the blue plant photoreceptors are likewise stimulated by UV, and the UVB chromophor overlaps into that as well. So HPS may...

All the soil outdoors has most its nutrients only in latent organic form yet the rainwater leeches mineralized ions from the soil solution and into the groundwater -or sea- and this is where e.g. the sulfur or nitrate in tapwater comes from, and these 2 do also have a circle - from and back into...

"ABSTRACT The transformation difference spectrum for phytochrome (Pr spectrum minus Pfr spectrum) in pea tissue is determined below 560 nanometers and compared with similar data on phytochrome in vitro" "DISCUSSION A comparison of the transformation difference spectra for phytochrome in vivo...

He's talking about senescence, which is induced by a cooler termperature shift in annual plants, you know very little about plants it's reveiling.

There's still the option left to transform the planet into a "Borg"-homeworld where only synthetic life can exist. It may even be a natural evolutionary process given how technology can evolve, and take over, at some point :blsmoke:

You gotta read that in a geometrical way, and yes, geometry is also based on math in a way. The link I provided explaines all of that, why go at length and formulate such a nonsense argument. You gotta start reading to get things in your brain, or maybe you're just one of these politican types...

Computers are very stable. Humans - not so much. Esp. not when drunken. Or animals. Look up how many children are biten to death by dogs, yet we allow them to roam around. They are dangerous, can decide action completely on thier own, and sometimes even think they can attack humans due to their...

It's not even clear if an AI is actually even intelligent, as that very word lacks a general scientific definition. The human brain has about ~110 different cognitive abilities, which give us more power than any other lifeform, but a computer can only best us at a few of those, never all...

The "Big 3 C" are where are problems come from: Capitalism + Consumerism + Cowfarts :D

VPD tells you how to optimize your environment for optimal photosynthesis/stomatal conductance. Preventing mold is just a different pair of shoes. I've seen grows at 90% rH where there was 0 mold. And some at 30% rH where all tops developed greymold. Botrytis initially dwells on dead tissue, and...

Thing is, white chips are around 3umol now but still lacking anywhere from 300-420nm and 680-760nm. Some monochromatics can match that efficacy while the 660nm easily top that by +30%. So the combination of both may lead to (a) higher system efficacy (b) broader spectral output One may just...

Biologically it's the same species, but I doubt hemp (fiber- or seedhemp) need increased S towards end of flower. Heck, fiberhemp isn't even flowered out - its quality sharply decreases with the onset of flower so they select cultivars to flower very late and strive to cut it right early...

Yes, the Ca-ion serves also as an important, even crucial, messenger or exchange ion and it is because of this relation, or rather antagonisation, of the K-ion which opens up ways for cells to regulate its own internal turgidity etc. For this, Ca is separated swiftly from K once it enters the...

3 weeks in is just after stretch phase done. My response was to a claim of "pre-loading Ca before harvest" so this should be within the last 2 weeks, so week 8-10 for conventional drug-type strains... Absolutely not, at least not within plants where actually quite the opposite is true - Ca has...

It's broscience - "loading up Ca" (lol). How is the plant going to be loaded up?!? And exactly this macronute which the plant can only load into the phloem in minimal amounts, and neither can it retranslocate it. As there is no need - the soil outside is full of Ca. Preloading other macros (NPK...

It's an exception and not what you're looking for. May be too much light/heat/stress. But Sativas that have this habitus generally flower way longer and thus you gotta keep the feed up as well
