You sure about that.

NASA says differently. Co2 levels are currently at the highest levels in the last 400000 years and are continuing to rise.

Yes I am sure about that.

400,000 years is a mere hiccup in evolutionary time. Plants evolved 700 million years ago. As much time has passed from the stegosaurus to the tyrannosaurus as has passed from the tyrannosaurus to modern humans.

If plants evolved over 700 million years that makes 400,000 to be equivalent to one day in 5 years.

(I had to remove the nasa link because I can't post links till tomorrow)

When the dinosaurs were wiped out from the meteor leading to the rise of mammals, the ancestors of human beings were still small rodents. Plants had already been around for over 600 million years by then.

the first three billion years of life on Earth was just single cell organisms. Geological and evolutionary time scales are difficult to comprehend. Numbers get so big as to cease to have meaning, we can only talk in analogies.

This is why any light you give your plants stronger than about 1200 PAR cannot be used without supplemental CO2, and there's prolly other limiting factors as well.


If you compress the time plants evolved into 5 years then 400,000 years is like one day.

400,000 years ago humans were almost identical to what they are now. 200,000 years ago Homo sapiens sapiens, was fully modern. Not much happens in 200,000 years.

It took billion of years for the oxygen to get into the atmosphere, it was a by product, a waste product of an inefficient biological pathway, when the air was filled with poisonous (to them) oxygen, they mainly died out and were replaced with a much more efficient pathway that uses oxygen and has CO2 as a byproduct. It took about 2 billion years. In the past oxygen reached 35% which mean that fires occur very readily. That's dangerous. Everything is nice and balanced now, but plants evolved to make use of massive quantities of CO2.

400000 years is enough time that plants would have evolved to use the levels of co2 present. Plants don’t require 10’s of thousands of years to evolve they can do it relatively quickly compared to animals.

You honestly sound like your talking out your ass. Put some science behind what your saying or gtfo.

What about all the co2 FROM CARS N SHIT THO

Take a photo and post that ? :roll:

I'm using the ViparSpectra PAR700W in a 60x90cm area. But I have a more elaborate post ready to put up tomorrow. For me to get a better light I'd have to go up to 200W of ChiLEDs but that would cost me 4 times the price which is out of my range.

I am a convert to defoliation to increase the yield and quality, check this out... There's only 10 hours between the defoliate and the shot the next morning and 4 of those hours are no light.
