ive done some reading and i am struggling to find much links besides a few words,
basically outside the ppm of the air is 400 and used to be 300ppm of co2, and thousands of years ago used to be 4500ppm, it went down and down till it was almost 0 till we struck the industrial age and it climbed back up to 400, great,,,
California has 400pppm co2 and the sun, giant cobble tree bushes that look insane and require ladders,
in the grow were told in order to handle high intense sunlight light we need to have 600-1200ppm co2, and without it cant handle much light, is this another myth that has been spread from sealed grow rooms? as its sealed you would have to replicate the outdoors more via adding co2,,
in a vented tent were constantly moving the air refreshing the levels of co2 with same as outside air constantly,
unlike a sealed room as they eat it it will decrease and oxygen will saturate, so you spray bursts of co2 high enough to cope with their eating between drops and being that the max before the decline is still higher than the minimum results will show better as the lowest spike after a feed doesn't sink below natures level of co2,400ppm
they say co2 is a waste in a vented room yet many are trying to do it still , im wondering as i use intense lighting and do not supplement co2, but stil grow big plants .. is it a miss communication again like many mixed things i find online like someone does a banging grow co2 sealed the lot and trying to chase him people are like its the co2 get co2 then there all buying co2 and recommending it and blogging before long a trend has started , forgetting that the vents from outside are replacing the same co2 level that nature provided to them who got 4 kilo 20foot trees in the soil ?
or do we need to spend the effort to add co2 ?
big growers years ago never used co2 that i was with some with crazy yields like heath robinson
