and to answer some of your questions leadsled. without cooling the room whatsoever it peaks around 87. does adding co2 from a bottle create heat? i was told you can run a little bit higher temperatures when running co2.
Bottle c02 does not add heat nor humidity.
TO clarify higher temps for c02.
higher temps for c02 means running in the higher range of more like 78-84f rather than 72-78f (or maybe higher) without c02.
Above 85f plants stomata can close and c02 is better not probably not being used until temps drop back down. So ideally you want to try and stay below 85f.
and i have NO EXHAUST. only an intake fan which has ducting thats pulling cool air from a concrete corner of the basement. the temps in this area range from 65-75* when i pump this air into the room it stays around 82* and the only way air is exiting the room is around the door. everything else in the room is got caulking/expanding foam. and once i got the co2 i planned on trying to seal the door even better.
Alright now we are getting somewhere. Bingo! There is a way you can improve your enviroment.
Ideally you should have intake exhaust for air exchange. That is how fresh c02 is given to the plants.
Would be better to use air exchange for now and try and keep temps cooler at 82. I bet you would improve your results with that for starters.
Good way to start now then can add the c02 later.
as for getting a ac and humidifier the AC i planned on getting after this run. about 350 for the unit i had in mind. and then for the humidifier i think those are pretty cheap but i really wouldnt know how to control it, like wouldnt i have to get an environment controller to do that? i dont want to leave it on all the time do i? i go to my grow room once or twice a day.
good plan, better to go overkill with the ac. I find it is safe to get at least 4000btu of ac for each 1000 watts of light.
Regarding the control for dehuey.
No, Many de-humidifers have build in controllers.
You set the % rh you want and it starts and stops once RH passes the level you set. With your dry room it may only be needed during lights off when you seal your room. The ac does remove moisture as well, but not as much when lights are off.
If it is only needed during lights off, then you can use a timer. When buying a ac and dehumidifier I recommend checking into auto-restart units. They. automatically restart after a power outtage. They also will work with a timer.
best to check and see where you are with your temps humidity at after getting the ac. Then decide next equipment to get. I got the ac first then added the dehuey when i got into flower. My room is fine with just an ac in veg.
Some rooms are very dry and need to add humidity. You do not see it often but it is important and can make a dramatic improvement in growth.
Not sure on commercial models. A Humidifer would need a enviromental controller to control it. I use a residential model with a dial and use it with a timer. Ideally you would use a controller to ideally control all aspects of your room. temps rh c02, etc.
and my next run i am DEFINITELY running a single strain. most likely blue dream, since i have some experience with it now. i wanted to switch to like g13 or blackberry next run, but i think ill stick to what has been working well for me already.
Grow what you like and enjoy. My yields increased once i started mono cropping. All the little things together add up.
Nice to have variety as well. My and a few friends that grow decided what strains we like. That way we trade so we can have some variety between us. Also helps to keep the genetics going.
