I've always cut mine back down to normal levels at the end of week 5, 350 ppm. unfortunately I can't comment otherwise. If u run it @ 1500 till harvest I have heard it can decrease potency.
if you run it to the end you may find that your strain doesnt want to finish - it will just keep foxtailing and putting on weight - wont do much for flavor or potency
really you only need to boost co2 to about 1200 from day 21 flower until 14 days (or more even) before the chop
So are you saying cut it off completely or just back off a lot mind you im in a sealed room...
CO2 in higher concentration encourages the plant to create leaves as a means of storing the extra carbon, which at very least increases your leaf to calyx ratio and promotes chlorophyll production as well.
Veg 82F.....1500 ppm CO2
Early Flower 78F......1000 ppm CO2
Mid Flower 75F.......600 ppm CO2
Last 2 Weeks 72F......300 ppm (ambient) CO2.....solution temp 60F
If you were running perpetual sealed with a veg room and 2-stage flower room exchanging air between each other, where would you keep your temps/humidity/CO2 in this setup?
Are you dumping air from the veg to bloom, vice versa or perpetually back and forth?
You may have to compromise and shoot for something in the middle if it needs to suit both.
That makes sense uchq... Where you getting your numbers from? Do you have any personal grow pics I could see using those numbers? I would like to see a personal grow pic and know what you guys are personally using and doing over there...CO2 in higher concentration encourages the plant to create leaves as a means of storing the extra carbon, which at very least increases your leaf to calyx ratio and promotes chlorophyll production as well.

well ok pics I can understand but I wanna know what your running in your personal gardens... You can at least tell us that...
Here's a chart better exemplifying the trends I'm referring to. In our observations, though total weight was typically 10-15% higher with CO2 run @ high ppm to harvest. The down side seems to always be too much of this was leaf and not bud tissue as well as being greener at harvest as opposed to bronzed and vine ripe.
We're here to offer support which should be taken with a grain of salt, as should all opinions.

Currently, a small R&D garden 6X 1000 with a UC 20XL Double Barrel.....but the opinions I share are based off of 20+ years involved with agriculture and hydroponics at both a hobby and professional level.
Fluffy....for from it, like rocks with a lot more leaves to trim.
