Please help me figure temp and humidity in flower! Co2

Grow Cycle Flowering
1

So, in my flower room i have (4) 700watt led lights that are over 8 large plants (gotta grow them big due to numbers restrictions). I have different stages of flowering plants in this sealed grow room that i have 1200ppm of co2 in. I have a mini split and a big dehumidifier so i can dial in the vpd im after. However i get all kinds of conflicting info on what my temps and humidity should be. So i need your help!
My leaf temp is ruffly 2 degrees cooler than the room air. So a vpd chart (pic) with that leaf offset says ill be fine at 82f and 55% humidity. But im getting people telling me thats wayyyy to hot in flower. I also read that co2 at 1200ppm you should be running in the 80s. What should i do?

  • Day temperature range 72 – 85°F (22 – 29°C) | Night temperature ange 55 – 70°F (12 – 21°C)
  • Relative humidity set to 50 percent (Safe range 45% – 60%)
  • Target CO2 within 400 – 1,500PPM

How late in flower?
If it is within the first 3 weeks of flower, I’d say you are good.

Later you definitely want to drop the temps.

I usually ramp my temps down… If possible during mid to late flower. As well as lowering the DLI. This will help prevent heat damage and evaporating terpines.

Flowering Stage: In the flowering stage (when cannabis plants start making buds), it’s best to keep temps slightly cooler, around 65-80°F (18-26°C). This isn’t for the plants themselves as much as to ensure the best bud quality. Slightly cooler temperatures in the second half of the flowering stage helps produce the best bud color, trichome production, density, and smell. To really bring out colors, aim for a 10°F (8°C) difference between day and night. More about temps in the flowering stage

This is one of those things as is a lot of things when growing cannabis that is debated and if you research different companies the suggestions change. Good luck with your grow my friend
