5000 Watt Co2 Enriched Sealed Grow Room (pics of week 3 flowering)

Hey everyone, this is my second grow. I am running 5000 watts HPS in my flower room. These are pictures of day 26. I installed a CO2 generator by day 14 of flower. I was so impressed with the results I wanted to show everyone my setup.

I am running this batch 100% organically. I mix my own soil! The plants love it and I don't have to flush. This is my first organic soil run, so I'll keep you all updated with the results.

Sorry for the lighting, I'll catch my plants next time right before lights go on.

I am growing some Northern Lights and Blue Cheese from Barney's Farm and sativa Skywalker OG (clone only from California).

I have 20 plants. This is a legal medical grow. :)

That's really amazing work your doing +Rep!

Is this 4 weeks from when you flipped to 12/12 of 4 weeks from first sight of bud?

I'm a 3 weeks at 12/12 and my buds are half that size, if, under 3000w no co2.

Nope, 4 weeks from the moment I flipped to 12/12.

Like I said in the beginning, I have installed CO2 and have been impressed with the results. :) I run my room a little warmer than before (85 F) so that my plants metabolize faster and uptake the extra CO2.
 
there looking real nice
heres mine 32 days from 12 / 12 flip 1350 ppm of co2 1350 ppm of nutrients organic soil 8000 watts
Beautiful! Are you using a CO2 PPM sensor/controller? Have you grown without CO2 before? If so, are you noticing a significant difference in yield? This is my first time running CO2 and my plants look like they're on roids compared to my last grow. I do have every element perfect though.. Temperature. air. water.. nutrients.. etc.. :)

i have run co2 3 times and yes seen approx 40 percent more gains yes the real co2 set up will have 2 litre sized colas in 3 weeks time :))
 
yours looking real nice as well you i stop co2 end of 6th week and only feed til harvest
Why discontinue CO2? I know high times growers report lowered potency when using CO2 near the end of flower, but from the growers I've talked to, they say that their plants bulk on the most the last 2 weeks of flower, and they don't see the point in stopping CO2 and none of them have noticed lowered potency?

I also hear that cutting off CO2 2 weeks before flower helps the buds ripen and shocks the plant into producing more THC by depriving it of its previously high CO2 levels.

Personally I think I will keep running CO2 till harvest. :) My plants don't all finish at the same time, and I want them to pack on as much weight as possible.
