Currently I have plans for (2) 20 light flower rooms and (2) 10 and (1) veg room. Two flower rooms will be 1500sqft. Two others will be around 750sqft. Veg will be around 580sqft.
My question is on my calculations for BTUs when formulating for the rooms temperatures.
I have been using:
1kw= 3500BTUs
1kw=1000w
Room Area BTU = L x W x 40 (48 x 20 x 40 = 38,400)
Lighting BTU = Total Wattage of all lights x 4
So for 20 lights I would have:
38,400BTU from room size
20x1000w = 20,0000w
20,000w x 3.5 = 70,000 BTU from lights only
20,000w / 2 x 3.5 = 35,000 BTU from ballasts
Total BTU to cool room = 143,400 BTU
Can someone verify if I have done the right equation? if not please provide any advice or additional info on further steps. I know machines such as mini splits, dehu and co2 will emit additional BTU's. For things such as fan (700BTU?)
Climate Northern CA so it's 100+ Summer and low 30s winter nights.
So it would be the 5k BTU, so even more. Curious how to figure out the BTUs per hour required to maintain said space at 75-80 degrees
You can't crunch numbers like that, too many variables. What is question? What you need to keep ambient temp?Currently I have plans for (2) 20 light flower rooms and (2) 10 and (1) veg room. Two flower rooms will be 1500sqft. Two others will be around 750sqft. Veg will be around 580sqft.

I built a room with 82 gravitas in it. They had to use arctic insulation palling around walls and litterally strapped a central air condition unit to each room. Your talking multiple thousands of dollars a month in electric. And need really heavy wiring or it will all fry. Melt the wires. So start with rooftop ac units.Currently I have plans for (2) 20 light flower rooms and (2) 10 and (1) veg room. Two flower rooms will be 1500sqft. Two others will be around 750sqft.

I know grips of growers but can't name one that would ask that question. But I get what you're saying.If they are in shasta county like tge name implies i coukdnt inagine them being that ignorant to the basics of growing. Sometimes people jus wanna reinforce their thinking so they cone gere to the forums. I doubt they wanna hear u guys tell em tht tgey dont k wo what they are doing even when u dint know the guy. If u are around tge redding area hit me up i know alot of big indoor growers and can prob answer everything u need to know
Vaulted ceiling? Heat risesSorry for the confusion, was in a bit of a "mad scientist" mode last night after trying to figure my equations. I am starting with (1) 20 light flower room for the first harvest. The additional rooms are future planning which is why I am trying to equate the math to limit surprises. Each building has different dimensions, with 2 buildings have flat ceilings and the other having slanted which is why I am questioning myself as I have always had 8 ft flat ceilings. May be a case of paralysis by analysis. Thanks for the input
