I swear by green planet nutrients. They are the best!!! 
If you wanna grow the best you have to use the best.

I think in the video it said it puts out 1500 to 1600 ppm.

I wonder about how it would affect TYM count. I used to brew alcohol in big jugs, really similar recipe. I don’t know enough about how it affects TYM count in finished flower though.

Here is a link from a company that sells test kits. Probably expensive as you have to click on a buy now link to see the price.

“1 hectoliter of wine at 13.5% potential alcohol produces 11.5 kgs of CO2. 1 hectoliter of wine at 15% alcohol produces 13.2 kg of CO2.” A hectolitre is 26.417 us liquid gallons
There seems to be a formula for the total amount of CO2 produced over time if you know the alcohol percentage at the end and the volume.
For every 1 mol glucose consumed, 2 mol of ethanol and 2 mol of CO are produced. Thus we have 10.02*2=20.04 mol of total CO produced from fermenting this 1.060 wort to 75% apparent attenuation.
Adding oxygen while brewing might change the formula a bit since you’d be making vinegar I believe

Due to oversight on my part I will have to run floraflex propot drainage system. The 4x4 fast fit tray table does not fit inside the tent 
. Also went with front row ag for nutrients.
