Good day RIU,
After few runs using CO2 burner.
Still having plant problems I can not figure it out.
Plants stunned and leaves turned yellow after two or three weeks after flip.
They look fine when I switched 12/12
I did have tried few runs with different nutes schedule. It just didnt work.
I also have another tent with pretty much the same setup. vent out the air instead of CO2 burner.
That one good pretty well.
so I assumed CO2 this the factor that cause something I missed to stunned the plants
Here are some numbers of my tent in CO2 enriched room.
TEMP: max 81F min 75F
RH: max 78% min 65%
CO2: max 1200ppm min 350ppm
I use grow tent, and I put burner out side of the tent in the room.
when burner shutdown, CO2 ppm still raise few hundred ppm.
as I mentioned above the max its 1200ppm, but I only set like 1000ppm and 50ppm dead band on the controller.
right now they are 23 days after flip.
I change out the res with fresh nutes
It looks like they are still getting worst, so I cut off burner today.
the other thing this i dont have any exhaust for the room.
I just closed door and window run mini-spilt and burner.
If not running burner, CO2 range stay around 300ppm would be enough?
have some pics of stunned plants
Any one have experienced grow in CO2 enriched environment please help!
Cheers and happy grow
