Basement furnace and co2

[Guest]

only problem with water cooling like that is that if you are on well water, then you will be running you well pump the whole time to feed the chiller, if you are on city water, well, you'll have to pay the water bill.

It's on a thermostat so it runs when the temps are above only. I've never payed for water in my life in the Vancouver area. I guess it's different in some places.

Is running C02 anymore productive in terms of grams per watt? You get a higher yield but you use more energy because of the AC and dehumidifier. Although the lack of fan extraction counters some of this power usage. How much power in terms of AC and dehumidifing do you need per kw of lighting in northern climates? Assuming that you are using energy efficient AC and dehumid.

How much time in the day are they on when using a thermostat and humidistat? If they don't need to be on that much then power consumption might be quite low. I've read that plants can tolerate higher temps with CO2 enrichment, which would help save energy. What temp is best with C02? Thanks.

Yes CO2 is more productive, you get more yield. It doesn't matter about using more energy because of AC and dehumidifer when using CO2, because even if you didn't use CO2 you'd still need an AC and dehumidifer...

Typical AC=500-700 watts
Dehumidifier=500-700 watts

The amount of time they run depends on your environment.
Yes plants can tolerate higher temps with CO2, but i wouldnt go over 95. A good range for CO2 is 80-85.
