    Yes it works very well. Damper it works even better. Very good safety net. I do it and feel good about going to bed in the summer with my undersized Split system

    Can you tell me which portable water heater and which pump you bought on amazon?

    Also do you know, how long the heater is on to up the co2 level?

    i moved the propane tank back into the grow room.it only got me 1 more day out of the tank.guess running in mid 70's is using alot more co2 then i did running mid 80s in the summer and spring

    Seems like I can source that modell of heater where I am :-) What pump are you using for it? I saw they sell it with a flojet pump which is 12V, which means I would need to run it from battery. I think that is not the best way....

    Also I saw, that it gets ignited with 2 D batteries. How long do they last?

    Did you hear anything relating to incomplete propane gas combustion with these water heaters? I heard if you have incomplete combustion it harms you and your plants....

    Ehm, sorry, I am still not sure how is the relation between CO2 consumption and temperature. Because you say that you have to shift the tank sometimes to lower the consumption? :/

    i am using a utilty pump from a hardware store or walmart. 1/3 HP Submersible Utility Pump something like that.31 bucks at walmart.
    mine has been running on same two batteries for 9 months i think.
    i moved propane tank in room thinking the cold in the garage was causing too low of pressure in the tank to let water heater run.i did get one more day of use from the almost empty tank by putting it in the 72 degree room.i do not know why i am using so much more propane now then in the summer especially since i am running the temps lower and most everyone recommends running hotter with co2
    plants are doing great with temps in 70's .they look better and yields are up since i lowered temps.

    That is strange... What do you guess, how much percent propane you use more now?

    Not true. Have you ever used one? Dual hose a/c does in fact pull air from the room, just not as bad as a single hose unit. You can still use them if you take them apart and modify them. Here's my thread where I did jut this https://www.rollitup.org/t/modifyin...sealed-grow-room-w-co2-tutorial-w-pix.887831/

    what do you guess, how long/often your humidifier is running?

    I got one which claims to do 105 pints a day (they claim it can do this at 80 % humidity and 30 degree celcius) and 775 watts. But I am wondering if it is really strong enough.

    Buy once cry once
    I have a Quest Dual 105
    I love this unit, it replaced a 140pint Dehumitifer, this runs less power, doesn’t kick on as much, draws less power too.
    Only complaint, it’s big . But built well

    no idea how often it runs.my guess is fairly often since my temps stay pretty stable.if i notice temps are getting lower i will lower rh setting so it cycles more often .usually have it set between 50 and 60 % but have gone down to 40

    I looked at Quest, but it costs 8 times more than my unit.

    Maybe get a 4 to 500W wall panel heater. I would at the minimum put it on a timer to come on periodically in the dark cycle. They are normally set internally to keep the room at about 25C

    If it is cold at night. The larger the gradient the more stretch you get.
    Basically everyone should have a way of controlling dark cycle temperatures just as they do for the light cycle... so maybe you too yeah.
