I’ll be honest I know almost nothing about the metric system…but slowly learning.
My question is RQS list indoor yield by meter squared.
Now if I did the math right ;
Tent 5x5=25sqft.
Convert 25 sqft x.093=2.325 m2…?
Now if it says ( random numbers )10-12 oz/m2???
To me it sounds like it’s saying the yield would be 20-24+ oz from one plant???
That’s a lot for one auto…at least in my limited experience…but if someone can explain this maybe ? I would appreciate it.
Yield is a tough one - everything depends on the grow, if you do a good job then it depends on the length of the veg period (for photos anyway).
With photos, you can expect the yield to double with every 10-14 days extra veg time.
For autos, you can estimate the yield by using the wattage of the light - eg expect 1g per watt or whatever.
For my photo grows so far, under a 300W lamp in a 4x4 I get about 2oz per plant with a 5 week veg, 3-4oz with 6-7 weeks. I have no idea if that’s good or bad but it suits my purposes.
I was just comparing time frames this morning because my F1 is about a week behind and I saw the the indoor yield listed as oz/m2 and didn’t know how it worked. I’m happy with what I’m getting it’s just more curiosity for better understanding mainly.
I know 3.78L makes a gallon and measuring spoons with ml amount on them😁
When they are doing those numbers i don’t think they are basing it off of one plant. They would likely have a few packed into that 1m2 when you see things like 600g/m2 because a lot of companies encourage a sea of green approach to get you using more seeds…
That sounds about right 
.
But then I also thought maybe it meant 1oz to 1m2 which would be a little over 2oz for my tent size , which is about what I got last time.
It was an insomnia moment and just got me thinking is all…I mean I’d love to pull 1 1/2 pound off an auto but I don’t think it’s feasible. A photo I can see easily if done right.
Breeder numbers are a sea of green. Wall to wall. When i see those numbers from Breeders. I just compare them to others from strain to strain. So you can see which strain is higher yielding then another. So you can kinda know what to expect from one plant to another.
Speaking about autos, i was pulling about 3-4 oz on average per plant.(Fully trimmed) my last 2 autos i ran pulled 4oz each. I probably missed out on more yield as i had issues late into flowering.
4oz is good enough for me per plant. So i was happy enough with the results. Eventually I’d like to get into the 8oz range per plant. Which would give me a pound per grow. (I grow 2 plants at a time)
I got 2 going now a Do-si-do and Orion F1 both autos…my first double run so we’ll see how it goes.
dunno why breeders put the estimated yield per sqm.
a throwback from the 70’s? Outdoors? s
We have found it better to work out efficiencies using the grams per watt method.
type in ‘best weight gram per watt’ into google and they will tell you 1 gram per watt is excellent…
its definitely something to set your goals to.
My mentor gets an average of 2.15g per watt (weight in the bag per annum / light/LED watts)
he smashes the breeders "weight per sqm/foot whatever’ its a dumb measurement.
2.15g per watt, growers goals right there lol
I know… I wish…
His best run was 2.6
We have experimented with this for a while now to find the sweet spot for vege time vs yield vs cost.
For us and the style of grow its 8 weeks.
Yield may double every 10-14 days to a point but it’s a very small window for young plants.
It doesn’t scale once youre over a few weeks.
Yield won’t double if you run a 6 week plant another 2 weeks, at least not for us.
But yield will be more on a single 8 week plant vs a 6 week and a 2 week plant combined.
@Crackadoo
I wouldn’t know what to do with that much considering I got over 2000w , but a nice goal to reach for in the future after I get things dialed in better and more experience.
It would be a challenge but i would find a way to use it all up in one way or another. All the edibles and hash and extracts you could imagine would be getting tried
I want to learn a simple way to heat extract rosin to try , and then see if a heat press would be worth the expense or not.
@Crackadoo
I just sat down for a minute and did some math:woozy_face:
. I really hope that is for an entire crop of multiple plants and not just one. But either way I’d be in a state that already has everything in place then become a licensed grower/distributer for local dispensaries and watch the money roll in.
2.15x2000÷28=153.57 pounds…
Great info thanks. Yeah I realised after I posted it’s not infinite or you would see some crazy yields
lol the power of the quote
2.15g multiplied by 2000w = 4300g then you may have to google like I do how many pound that is
Fun fact - We found over the last couple years we got more yield splitting that light wattage up to add under the canopy… 2x 500w lights under and 2x 630w over will yield WAY more than the same wattage above.
Do you use your under lighting the whole run or just through flower?
When we flip to flower.
If you love to lollipop up high like I use to, it takes a bit of practice to start to leave more on. I still take too much away and lose yield.
But there definitely is a sweet spot where the light penetrates right through and meets in the centre
Thanks, its something I’ve never played around with yet but i have an old 400w blurple sitting around collecting dust so i might as well throw it in for the next run. I usually strip the bottom third of each branch so ill start from there and see how it goes
