[quote name='"MTgreenbud"'] I can respect your point of view. but the science is right on. weed will grow in most any conditions. but i see what you were getting at with that. yes people want dank over ditch. and promoting photosynthesis through light and co2 is what produces dank. that and a well developed strain. what i am talking about is a small scale 1 plant grow for a better yield. not a closet full of plants for an average yield. so many times you see people stick a bottle with sugar and yeast in a grow box thinking that it is helping, and the truth is, i barley raises the CO2 levels to 300 in most cases, the vent fans push it out as fast as it is made and a little bottle dosnt produce near enough to change that fact. dry ice is better on that scale but still not effective. target levels are 1300 to 1500 ppm in which to achieve on a large scale you need tanks, regulators and cycling fans which exchange air only every 2 hours. by reducing the atmosphere in the grow space you can control the co2 and humidity and light more effectively, i believe you were more focused on the principal not the concept of science. either way, everyone is entitled to their opinion.[/quote] Sounds like your on the Starship Enterprise and use advanced technology. Your busy doing things that are not done in organics. Do you have a tricorder and if so can I borrow it? What your saying goes right over my head, so did some of JC's Grow Bible. No opinions have been given or implied. I'm usually not focused enough on anything to have one. Unless its great food and I've got the munchies.
