Sealed vs vented electric cost

[Star Dog]

I've no intention of installing Co2 not even for free I've no use for it, it's more expense, time dialing it in and learning it, I'm taking it easy from here on in with 4 big plants from the mothers I've collected.

Eta...After thinking about it obviously I must include fresh air if not Co2 which totally defeats the purpose of sealed rooms.

Ok...i need to re think this Co2 isn't an option for me.

I wasn't even aware of these "air to air heat exchangers", I like this technology.

Yeah they're pretty cool! In the HVAC world it is referred to as an ERV (energy recovery ventilator)
The brand I install is Aprilaire

It's generally cold and damp here I'm no stranger to hid

That said I refuse to ignore the benefits of led, i don't read technical stuff I've little interest in it so I'm not judging by anything other than the results.

That's the money! No remote ballasts and drivers needed here! Looking healthy and happy!. What do you typically flower in there or is that only for veg?
Everyone probably knows already but cmh bulbs have a mogul adapter so you can use your hps hoods if you want.

It's not as bad, expensive or complicated as some think. Very simple and inexpensive... Also, you now control your environment, it doesn't control you. Plus, you'll notice the yeilds. $30-48 is x3 small tanks (once you own them) a grow to get 30#'s. Could be less using a co2 burner and propane. That's just the regulator on a timer. With the little portable sensor in the room for your monitoring pleasure.

I use it for a couple of weeks veg then flip them, I've usually got them well enough on before they go into that tent.

I think there was 9 plants in that crop, it was early veg hence the hid light.

I'm thinking 8/10/12 plants is done with now, I'll only be growing 4 plants now I've mothers I'm happy with.

If i can maintain an acceptable humidity with 4 plants I'll be happy, if I can't I'll re consider a sealed room.

Thanks for your help and advice.
