The best way to re-mineralize organic grows is using a combination of brix blend basalt or glacial rock dust with high CGS ratings, gypsum , and oyster flour. Azomite works good but glacial rock dust or brix basalt has much higher mineral count and a much higher cgs rating. A cgs rating of above 2000 is considered excellent, the glacial rock dust I use has a CGS rating of 3000. You can also use Langbeinite to increase sulfur quanities in the soil or use an Sulfur admendment in your soil such as this http://buildasoil.com/collections/minerals/products/sulfur-90-agricultural

Like I said earlier, I grow both hydroponics (RDWC) and Organics (ROLS) and the ROLS is always more tasty. Soilless never can compare I have tried to do COCO, hydroton, coco in my hydroponics bucket, pumace, perlite, etc...none ever compare to my peat based ROLS.
Does a up taking plant know the difference between organic nitrogen or synthetic nitrogen?

The spectrum of the light directly correlates to the heat it makes. That is how they discovered IR radiation, read this article.

http://www.brynmawr.edu/chemistry/Chem/mnerzsto/Marshall-Infrared.html

It explains how IR was discovered and how it has a higher temp than other spectrums of light, the more IR in the light source the more heat it produces so not all lights produce the same amount of heat.
Sorry, I overlooked this comment. Wasn't ignoring it.

While IR is more readily absorbed by more molecules, it doesn't have any more energy to "heat" anything moreso than say blue light or green light.
The spectrum of light doesn't correlate to the heat it makes, rather it denotes the frequency at which those photons will be absorbed. The photon gets absorbed by a molecule and excites an electron which increases kinetic energy causing "heat".

IR (particularly long-wave) happens to be very absorptive especially to water molecules i.e. People and plants. But if all the visible light was equally absorptive, it would have the same heating effects as IR.

"Infrared radiation is popularly known as "heat radiation", but light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun accounts for 49%[19] of the heating of Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths. Visible light or ultraviolet-emitting lasers can char paper and incandescently hot objects emit visible radiation. Objects at room temperature will emit radiation concentrated mostly in the 8 to 25 µm band, but this is not distinct from the emission of visible light by incandescent objects and ultraviolet by even hotter objects (see black body and Wien's displacement law).[20]

Heat is energy in transit that flows due to temperature difference. Unlike heat transmitted by thermal conduction or thermal convection, thermal radiation can propagate through a vacuum. Thermal radiation is characterized by a particular spectrum of many wavelengths that is associated with emission from an object, due to the vibration of its molecules at a given temperature. Thermal radiation can be emitted from objects at any wavelength, and at very high temperatures such radiations are associated with spectra far above the infrared, extending into visible, ultraviolet, and even X-ray regions (i.e., the solar corona). Thus, the popular association of infrared radiation with thermal radiation is only a coincidence based on typical (comparatively low) temperatures often found near the surface of planet Earth."

Not to derail the "organic vs synthetic" discussion.

I am enjoying all of the alternative lighting tech and dabbling into led myself but why are we just not seeing eye candy Zombie heads like this popping up under led's?

Are any of the COB guys running DWC? Looks like feeding and strain + DWC, probably crazy long veg? Lots of light helps too.

Maybe just the strain, but I don't like the bud structure. Hehe. Sorry, I had to.
Weight wise, I'm sure that was absolutely amazing. But that foxtailing is out of control

i thought the blurple thing was dead, then i found this pink house douche bag


1 why is this guy not running home made cobs half the rated power, or even one quarter of the rated power
2 how much did the Swedish blurple maifa pay this cunt to say these unforgivable things
