Grams per watt is still a meaningless measure without some reference to time or energy consumed. Like gpw/kwh's or gpw over X weeks.

Well obviously, most use 2 week or 4 week veg and 8 week flower. No one measures grams per kwh, given electricity rates vastly differ. Thats why grams per watt is used.1kw is 1kw regardless of where you are in the world, whereas your cost to run that 1kw is not a constant from grower to grower and region to region. Obviously if you have a 2 month veg youll yield more. But thats on the fringes of how people grow, not the majority, but an exception.

Its not about the cost of energy, simply the amount. Its a far more accurate way to determine how efficient your garden is.

And when are they starting there veg time count? From pop or after the seedling stage or is it from rooted clone?
I don't think veg time makes a big difference in the equation as lots have a separate flowering tent so veg time fits into the flowering cycles anyway.

I agree that just a GPW is not the be all and end all, total electricity used makes a difference. After all GPW should include all watts used.

I did 3-4 weeks veg on that last grow. Don't remember exactly. All I know is I got the same yield as double the watts of HID, so I won't be putting my HID back up unless I need to heat the room and they turn out to be more efficient than a space heater.

Can you post a link to the QB's that your using? I'm pretty old school and like to stick with what I know works and for me it's the SE 600w. However, the savings on your hydro bill does intrigue me. I've tried to follow the conversion of a 2x600w HPS setup in a 5x7 to an equivalent LED setup but i can't really find it or understand it. Thanks!

I have 3* 600wSE HPS + 1 * 400w HPS in the same tent before, now I have 2* 260xl QB and 600H QB.

This is the v2 (I have version 1)

To replace 1200 Watts two of these would work since each is a replacement for a 600w SE HPS

The best I have achieved so far was 12 oz of solid bud and 3 oz of popcorn and trim from a single 315 CMH and the veg was under an actual 500 watt blurple. Next round indoor will be under 330 watts of cob and quantum and then flower with cob and 315.
2 sour kush and 1 white widow with a 5 week veg.

The blurple was good for veg because of the K. I think that light was 4k and the 315 is 3k so my 3500 and 4000 cob and quantum should fit the bill.

I've got 4 Gavitas, 2 rows of 2 and a 400w MH supplemental in between them. Split harvests. Last pull of 1 side was 3, this following one should be 4+, and the following after that is looking like 5-6.

20 plants at a QP a piece gives me ~1g/w. Of course, things don't always go according to plan...

Highly recommend the Gavita DE's.

Where do you see this at? Im seeing most 6-10 week veg in the LED section with great gpw results.

As a general rule of thumb.(breeders, books, DVDs) when breeders give a yield estimate its based on a 4 week veg and 8 - 8.5 week flower. I don't see why you'd need a 6-10 week veg with LEDs unless you're growing massive trees. LEDs are great for veg. If I let mine veg 6-10 weeks theyd outgrow the damn tent lol.

I'm guessing you mean from a rooted clone or for SOG?

Personally I grow from seed for mothers and then clone for the flowering run. So veg time would not include any 'mother' veg time. Flower veg time starts when the clone is rooted.

I would assume (perhaps incorrectly) that breeders would use the same methodology, as you need to pick the best phenotype from any seeds you sprout, so it would not be practical to include veg time in your mothers, it is irrelevant.

I do the opposite...clones are taken from seed plants, then the seed plants are flowered out to show full potential. Once I’ve harvested/smoked/evaluated the seed plants, then I can start discarding undesirable pheno’s from the clones. Then the tedious work of breeding begins when you start working the keepers.

Similar methodology. I didn't say I don't flower what I grow from seed. Of course you do that first, to pick your desirable phenos. Then you can revert your flowered plants if you have not taken clones before hand. But to the discussion of yield, I think most people are talking about a rooted clone, not a seed when they refer to the veg time they gave their flowering room.

I just think its important when people mention a short veg time like 4 weeks its clarified, otherwise other growers, perticuly new growers, have in unrealistic veg time in their heads.

I mainly grow and flower from seed as I have only just gotten a cloning space (I'm in an illegal country and clones are still classed as plants in the plant count) and every time I see someone say its a 4 or 5 week veg I'm like "no way, my plants 1/4 that size!"

To answer your question, from rooted clone, and not in SOG. How is a month a short veg exactly? If you cant veg out your plants in a months time, youre doing something wrong IMO.

Thats because new growers think that veg starts from the time the seedlings are above ground. Which is incorrect.

Growing from seed, 4 week veg is on the short side. Some strains wont show sex in that short of time even using 24 hour lighting.

Yes we have a germination stage and a seedling stage but its just easy to count days of veg from seed pop. And days of veg from rooted clone.
Is it a biggie? No of cause not but that's why we get people asking all the time is "my plant to small for such and such veg time" and usually no one asks the right Q.'s before saying "it looks small for".
From seed pop 8 weeks veg I recon would be more common than not for those not running SOG, especially for those running soil. Which fits into the flowering cycle of the flowering tent for those that use them

I usually veg from 5 to 8 weeks, just depends on the strain and how vigorous it is. And i start counting when the first set of real leaves is fully out.
of course i have room for 5 foot plants, 6.5 with pots, i guess a lot of people have less overhead room.
