I’ll say my last bill was 700 something. For 2 leds. And the dx hvac. And me living my life too.
The ac last month killed me. Added about $300.
Now that it’s cooling down I’m expecting the next run to be less. Prob won’t need ac.
I promise you I could add LED’s a drop cieling, and some, cheap plastic walls and reduce your hvac costs substantially, including CO2 gen.
Why on earth would you drop the ceiling height?

Because negative space is negative space. A well managed LED garden shouldn’t need more than about 10 feet. Most warehouses with HID have much higher wasted heights. You waste light, HVAC, CO2 and more.
Also drop cielings allow for gang ways and heat management.
How does the ceiling height waste hvac and co2? We are running a closed loop system so ceiling heights makes zero difference for co2. And I can’t see how it would either way.

Heat rises, cool air and co2 drop to the floor. Co2 fills up a room like you would fill up a glass of water.

Cielings add more volume or cubic feet to control. CO2 would fill the room like a glass IF every single one of us didn’t have fans blasting (hopefully in a high send low return wind tunnel) while the lights were on, and the CO2 should be off at night anyway.
You can’t slap some LEDs and grow like HID and be like where’s my savings.
Ok, so co2 is mixing up and around. In a sealed room there is no loss of co2, sure you filled up a larger area that definitely took more co2 to fill initially. But after that, the only co2 being consumed is from the plants.
Or personnel making entrance into the room
Believe me man, the volumetrics on a 45-60 day flip over the 1,5,10 years aren’t small, and CO2 was my last mention.
Present facts and not your opinion and I’ll start doing that

I thought the same thing. I have been using Lucas method a long time.

It’s not my opinion. It is fact. It is not on me to prove anything to you. You can continue to be a skeptic, or you could give it a try, or gasps Google it. This is pretty fucking basic LOGIC.
Why don’t you guys make a fucking “Growing with HID” thread. That way I can come in there and point out the only positive about HID is their capex cost.

So why fill up a pitcher when you asked for a glass of water? I believe that’s the point vortal is making.
More heating and cooling in a area of space that doesn’t need it doesn’t make sense efficiency wise. Why have 14ft ceilings when 10ft would kill it with led. 10x10x10 is 1000sqft of space vs that 10x10x14 is 1400sqft.
So on the daily your heating, cooling and filling co2 for 400sqft of volume you don’t need. That will add up over the course of the year I can assure you and it doesn’t take much math or science to understand this.

Hey I’m trying to understand exactly what you’re saying here.
I understand dx hvac to mean direct expansion hvac. This is the same as vapor-compression refrigeration. In other words, just a normal hvac system.
Hot gas reheat, as I understand it, is used to turn a regular air conditioner into a dehumidifier. You basically add a heater to the outlet of the A/C system (after the evaporator) so you can remove moisture using the system’s cold evaporator but without actually reducing the sensible temperature of the air at the outlet. The air comes out at the same or higher temp than when it went in but it had moisture removed and thus the relative humidity decreased.
If your unit is in dehumidification mode, doesn’t that by definition mean the propane reheater coil is required? In other words dehumidification mode=reheat coil activated.
If the reheater is not engaged then the unit is operating as a standard A/C and cannot control humidity separate from sensible temperature and it isn’t in dehum mode.
Or are you saying that when your hvac system runs in dehum mode with the reheater engaged you still need to run a separate propane heater in the grow space to heat up the room?
I thought the major draw of LEDs was that they give off much less heat vs HPS and can also put out a similar amount of PPFD as a 1000w HPS but at a lower wattage.
Let’s talk about co2. Yes it takes more to fill the room initially, but the only co2 being consumed is by the plants. Not sure how a higher ceiling consumes more other than the initial fill when operating in a sealed room.

Lol similar ppfd to HPS. In real world environmentals I consistently see well designed LED gardens at 1500-2000umol/m2 and hps at like half that.
I grow with LED’s too. Not once have I been talking to you about hps lights. I’m talking to you about consumption of co2 in a sealed room.

Like I said earlier. It was my last mention, because it is one of the lower value saves. But let’s think about it this way, using your logic. Reducing the cieling height only reduces initial fills.
If you reduce the cieling height by 10% you have saved 10% on co2. I want that 10% in my pocket. If you don’t that’s ok.
Reducing your attack surface/vectors almost always leads to greater effeciency.
The only drawback to led I see is the quality of the flower I was able to produce.
I have grows already setup for HID as far as ceiling height and cooling and dehumidification goes. With leds with warranties for grow GRN are only 500 it’s not even a capex advantage as you have to factor in bulb replacement for HID annually.
All of that being said I won’t believe that a technology is better for growing until it actual makes a better product for me. Maybe it will after a few runs, I have an open mind and appreciate results more than bias.
