I've been running at 1100, but thinking of kicking it up a few hundred. Curious what rates anyone else runs at. I have a co2 generator with a controller so it keeps it right where I set it in a closed circuit room with 2 heatpump ac's. Last run I had my best yield running 1100ppm from start to finish. Pro-mix, 8 weeks indica strains, veg 10 week including cloner time. Getting this shit dialed in.... w00!
I dont run co2 but most people ive seen run around 1200-1500 at peak flowering, Ive heard anything above that is a waste but Im sure a fellow gasser will come along to clarify.
