    HRV anyone?

    yeah but your way does not get very much fresh air with co2 to work with does it? i wonder if co2 depleted air recirculates with your setup

    HRV anyone?

    ive never seen a hrv (heat recovery ventillation) used for a indoor in winter does anyone use it? if not why not? looks like a good idea to up air exchange and not spend way more in heating. imo

    Scientific proof that a ghetto (baking soda &vinegar) CO2 generator is pointless

    idk i dont extract air out of the room and i have 2 large dogs and myself that live in the grow room and a slightly cracked window. my plants are doing ok in a 2x4 so i think me and my dogs breathing is more than enough for veg.. once in flower i will up the air exchange certainly

    A design for winter focusing on and temperature control using hid for the winter cold temps and reducing heating bill by using a lung room.

    i will use the 250W in the 250W position of the dimmer to run it full blast its not good diming hid it looses lot of efficiency and par spectrum

    A design for winter focusing on and temperature control using hid for the winter cold temps and reducing heating bill by using a lung room.

    now if we are getting fancy i would elaborate a arduino system with temp and rh sensors that crack the window automaticly with a cheap 9g servo and give so much free humidity co2 and cold air almost for free.. but that would be another 150 bucks xd

    A design for winter focusing on and temperature control using hid for the winter cold temps and reducing heating bill by using a lung room.

    now that i think about all of it it would be better if i buy a dedicated tent 1.2x1.2x1.8 and run everything off 1 controller : minimum speed variable controller with temperature and rh so the controller itself is a 100 bucks but you get to run your system off 1 controller and no lung room...

    A design for winter focusing on and temperature control using hid for the winter cold temps and reducing heating bill by using a lung room.

    Thanks for answering, ive rethinked all of the above and now im more convinced that a actual minimum speed fan controller + a powerful exaust fan + dehumidifier or humidifier in the lung room + rh controlled intake in the lung room + heater directly in the grow space would make more sense...

    Hey tis is my first post i would appreciate any improvements of my idea or any commentary. Anyway.
