Honestly the gas veg speeds up by 3-5 days as its a new thing to me. 18 hrs for 7 years now
lets talk yield, .5g to 2.5 grams per watt. how can we get there?

Gas lantern is great for sexing seeds though

36 hrs dark excellent ares things by 5-9 days. The igniter and blood excell about 5 days. The koolbloom about 7 days.
But then again the way I feed is different than most

I'm all ears, do tell. You do one 36 hour dark period at the onset of bloom?

Yep yep. Ladies love it. Cubes nice n dry roots really thirsty when lights come back on.

Using glr keeps the plants just on the verge of flowering so the switch whenever you do decide to switch seems instantaneous 1-2days from my experience.
So far I've found this to be the case with every strain I've tried except Swiss cheese they simply would not veg under glr.
Thanks for pulling me into this debate again lol

Lol I know you love it. I'm adding more light to my veg and I'd like to see if I can shorten my bloom schedule to just 7 weeks. Both of these seem to point to me giving gaslight timing serious consideration.

This is how I kept my outdoor in veg during spring Id interrupt the rest cycle ... Going to try the flower times .. Got an extra tent and led

As always, I come in late in a discussion....
2,5 gramms per watt is possible.
If you veg forever, grow huge plants and flower a couple of months, on a big space and also consider fluffy weed as 'good' weed.
For a good comparison you need the following things:
Space x time x watt x gramm
I hardly saw anyone who is doing 5 or 6 yields a year do more then 1 / 1.1 / 1.2 gramm per watt on a regular basis.
I know that with Led more gramms per watt are possible.
But even then I see yields that look so horrible, with all kinds of fluffy shit, and even the smallest nuggets which they count in.
If you grow from clones + 2 weeks veg + 8 weeks flowering in a space 4 x 4 under 1 x 600 W HPS, then you are an excellent grower if you yield 600 gramms of dense buds. 500 gramms = still very good. 700 gramms = superb, 800 gramms = wow, 900 gramms = buy a new scale.

For max g/w yield you need to spread the light out as much as possible, probably 25-30 w/sq ft with LED. In this article, they got 422 g/m2 using 270w HPS, 497 g with 400w and 544 with 600w. So with the lowest intensity of 270w they got 1.56 g/w, with 400w 1.24 g/w and with 600w 0.9 g/w. So you can see that a large area is more important than high light intensity. You do get more yield but the returns on energy input diminish.
Interestingly, they also gave the weight of THC produced in the flowers and the total weight of the flowers so you can calculate the potency by dividing, and turns out that the potency was the same in all light intensities, about 14.5%. So higher intensity does not mean higher potency. One of those 315w CMH should be just about right for 1 square meter.

IDK, but at least it's the same potency. Actually, I find that the buds under the brightest light are the harshest. But there may be some density issues, as you said.

Have you converted the output of your lighting to PAR Watts per sq ft? It's an eye opener, especially when comparing to COB LED.

It's actually CXB COBs that I'm using, just supplemented with a few red CFLs because the COBs are 4000k. The study I mentioned was with HPS, that's all. I assume you'd get better yields with COBs, maybe 2 g/w, at similar wattages.

You're running 60W/sq ft of COB LED? No wonder you're burning them!
BobCajun

No there's no burning with the COBs, that was when I used a small HPS in a veg cabinet. Just some bleaching if they get too close. Not hot in there though, if you stick your hand in. The heatsink is outside the top of the chamber.

Just browse through the LED forum and you'll get it within a week or two. I didn't use a DIY version myself, just bought CXB high bays. Didn't need the reflectors though. I also took the driver and rigging off the fixture for less heat and weight. I put a long wire on the driver instead. It's like just a disc now, a couple inches thick. Here's a link to one site selling them. I used one in each 3'x1.5'x5' chamber, about 18" above the plants. Plus I added four 13w red CFLs.
