This week was amazing guys. I literally watched the buds getting fat day by day. I am still feeding with a similar program and adding Aptus Regulator once per week to boost silica and some other minerals like molybdenum and boron. I'm flowering my plants in a hot environment with CO2 boost. PPFD is high to support these settings and thankfully my the pots aren't getting hot. No fungus gnats or any other pests, no root rot and bad smell. Everything is perfectly neat and buds are exploding. My expectations from this harvest is really high and I'll keep adding CO2 for another week.
Some fellow growers asked for CO2 and PPFD measurements. I am sharing these information on this week's pictures. I got my CO2 meter fixed and I tested the CO2 PPM in different places of the canopy. Typical value for this grow tent with this CO2 setup is around 1100-1350. Temperature is fluctuating between 28-31 and the average PPFD on the bud sites is 1100 micro moles.
I'm sharing CO2 measurements right under the fan, where you expect it to show the lowest value. Then I'll also share the CO2 PPM value coming out from the air pipe, which is normally attached to the grill of the fan. Direct output is now around 5500PPM and in the first two days, the meter shows 10000PPM which is the max value that it can reads. This bucket yeast CO2 reactor lasts for four days and I'm refreshing the mixture twice a week. This is huge CO2 with a fairly low cost compared to propane burners or CO2 tubes.
Edit: I refreshed the CO2 bucket today and got you guys a video of the direct output. The system is outputting more than 10000PPM of CO2 and the meter can't measure it for the first two days. This CO2 method is a killer one for tent grows. Very low cost for very high CO2 concentrations.
Hope these information helps. Happy growing 💪
