maybe there is a way that i can lower my tent temperature. Fortunately my lights are the sf7000 from spiderfarmer. The have passive cooling system so most of the temperature comes from the ballast which can be placed outside the tent .if you're running exhaust fan at 100% i would not recommend adding co2.
it will be exhausted immediately so it would be quite costly to maintain proper co2 levels
need to be able to run exhaust at minimal settings to maintain co2 levels
first, figure out a way to maintain room temps 7-10c cooler than tent temps. then you should be able to maintain proper temps without exhaust at 100%
i can find some that can hold up to 50 litres of liquid but they cost like 350 euro and they are like 160 cm so they are far out of my budget and my space.Ahhh. Thats a food service style tank. 5 kg is ok. It's not a big space. It's probably big enough. Our soda fountain tanks are different. The other type is for welding tanks. They fit a lot more. But the fitting is different.

Look up a welding supply store in your area for CO2 needs.I do know know what is a beverage type but this is the biggest that i can get on my country. The regulator has a "european plug " as it says, This one can hold up to 5 kgs of liquid CO2
Thank you. I did and i found a 6kg for 90 euroLook up a welding supply store in your area for CO2 needs.
I bet you can find it waaaay cheaper .......all the bars in your area must use a 10kg tank to serve beers and sodas....ask them where they get it......its gona be much more cheaper than welding or aquarium supply....Thank you. I did and i found a 6kg for 90 euro
I am not growing yet with co2. I am at the seedling phase for the time being. But i plan to add co2 soon. I am cpntrolling the climate depending on what vpd i want . Currently i am aiming for 0,8 . My exhaust fan i sucking at 100% power and it cannot bring temperature under 26C. I am also providig humidity with an external custom humidifier i built so there is a little intake pressure from this too. I can make you a drawing of how my system works if you want and the max and min temperatures i can get compared to the current climate of the country i live in.Hey @goodbye95 please understand CO2 = sealed space. Zero air exchange. If it is too hot when sealed, you gotta fix that or you are not a CO 2 candidate.
Are you growing right now or could you seal it up and turn the lights up to 100% and track temps for a couple days and see how bad it gets?
He is saying that you cannot run exhaust if you are going to run co2. It doesn’t work that way. Have seen many many ppl try even after they have been informed and everytime its the same result. It does not work.I am not growing yet with co2. I am at the seedling phase for the time being. But i plan to add co2 soon. I am cpntrolling the climate depending on what vpd i want .

the light seems too bright cause of the overexposure of the camera. It is actually dimmed at 15% . based on the Pulse VPD chart i need 70% RH and 26 C to get the desired VPD . Meaning the conditions i currently have. I am measuring the leaf temperature with an 190euro Flir IR thermometer ,so i think i am pretty accurate on this. The current leaf temperature is at -1.5 C of the ambient temperature. Since you mentioned it though my light intensity at the current time is giving me about 300 - 400 ppdf which is like 20000 - 27000 PAR. i dont think i need more or less. Any comments are appreciated.Way to much light and your VPDis is inaccurate. You must take leaf temps into account. Under LED leafs usually about 4-5f cooler than air temps
VPD (vapor pressure deficit)
Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...www.thcfarmer.com
