What is your cost per gram to produce?

Its definitely more for 1st time growers especially indoors as you've got initial purchases that last a long time; tents, certain lights, feeding systems if you chose to use them, I'd be very interested to see how low you could get the number in a grow that wasnt industrial scale lol
 
I keep a log of most things. Here's what I keep track of or at least make guesses.

LEDs. I calculate this based on my actual wattage at the wall and my bills kva cost. X .7. Because they are off sometimes.

Fans, and ac, same but no .7 calc.

Nutes are fixed amounts with known cost.

Factor and amortize cost of equipment at 12% depreciation per year.

Cost of square footage of home as growspace. Mortgage/sq ft.

The only uncalculated variable is my labor. I can't charge what I actually make for a living, I can't use some arbitrary number either so I don't factor it, its donated. Thats probably a cop out but meh.

And water, sewer, trash. Same percent of the bill as sq footage.

We missing anything??

Cost of % of house for growspace would be for a business. Not real life hobby grow cost. You have a very comprehensive set of data points tho. Water cost would be actual cost of water not a % of the bill based on sqft.

I considered water, but last months water bill was 40 bucks and includes trash and sewer. Split that to just water then split again for house vs crop, gets down to a pretty negligible number really.
 
Hmm.. say average 500g per square meter.
Lightings about £10 per week per meter. average crop time about 15 weeks so £150.
Maybe £80 per meter per grow on nutes n stuff.
£35 per meter on coco/perilite.
So all in about £265 for 500g
50p a gram roughly-ish. Thought it would be higher than that.
(Edit) shit it is lol forgot about bulbs. £50 a grow for them so I'm about £315 per 500g.
And I've just realised my dealers upped his game cos I'm suddenly incapable of figuring out the maths in that haha fuck me running. Best bit of stardawg I've had yet :)
 
ive also considered calculating savings based on consumption, that is to figure i smoke a 1/2 a day on average, if i had to buy it id have to be a corporate ceo. Even tho I would smoke less if I was buying.
 
I’d urge any of your guys who are actually interested in a cost per gram, to consider depreciation and replacement of equipment into your cost equations.

Very small cost per gram in terms of raw materials, but true cost can vary real wildly based on labour input and what value you put to that, and method of grow.

It’s something fun to figure out.

In terms of raw material input I think I figured about $9.50 Canadian per ounce without factoring in equipment depreciation over time. That adds a few bucks a gram for sure (about $4 on a 5 year usable life and with LEDs).

But, I am a small time hobbyist and not paying any particular attention to maximizing that, or economies of scale.

I amortized all equipment over a 5 year depriciation.

That’s exactly what I do, just straight line depreciation over 5 years, because in my mind that’s about how long before it breaks or i upgrade. And it’s simple, and if I start going down the rabbit hole of complexity the equation starts to include a lot of shit!

Yea, thats what I think. Even if it doesn't NEED replaced I will see some Shiney new tech I just gotta have. Especially where lights are concerned.
