The light cycle times are pretty interesting topic. I guess it all really depends on your application. I'm a indoor - 12/12 from seed kind of grower personally. I can squeeze one more round a year that way by skipping longer veg times.
I like to start seeds on 12 hours of light or 13 or 14 hours while increasing the amount of light by 2 minutes everyday, until I reach 16 and a half or so hours of daylight. I have read that the plants respond to increasing daylight hours with rapid vegetative growth.

I have tried the Gas Lantern technique, and the only thing I do not like turning my lights on/off multiple extra times per day seems like that may cause diodes to have shorter life span.

If you want to get them taller, faster, then sure go with above 16 hrs of light. I try to keep my electric bill down.

Are you growing in soil or ? I have tried this before and ended up with puny harvest. Haven't tried any sort of hydro this way though.

I understand why some do it. I grow for me and the girlfriend only. I'm not on a schedule for anyone. I don't have to squeeze an extra round in, just grow enough to last until next harvest.
Same here, just for me and the wife. Gotta admit that it is sometimes hard keeping up with our smoking habits and staying within plant counts. Plant counts suck but at least I have a plant count, unlike some of the others on here dealing with looking at jail time for growing a plant, bunk!

I run a tote based DWC system in a 4x4 with HPS. I get a really good yield with HPS. I recently setup a new tote based DWC in a 2x4 tent with a Mars TSL2000 LED. It wont have the same yield as under an HPS but it is a fantastic light.

I still use HPS 600w for flowering, and 432w T5 for veg.
Edit: I am looking into other lighting iptions for the future, and I'll be behind tech by then too haha

I'm HPS as well for flower, last year I switched to CFL's for veg because T5 bulbs are so expensive. Recently found some T5 led's on the cheap(name brand though) but haven't installed them in my T5 fixture yet. Hopefully they are compatible with the ballasts in the fixture, if not I will change out the ballasts and see if I made a mistake wasting money on the setup. Lol. The CFL's have been great so far, nice tight node spacing and plenty of light coverage the way I have them spaced out, all while using less watts than the 54 watt HO T5's. Looks like you have the same fixture as me, I will try to change out to the LED'S this weekend and report back to you. The CFL's I have are 6500K 23 watt and I have 12 running right now.

Like 4 pages of discussion on light cycle and not a single mention of DLI. Come on!!

DLI is your daily light integral. Put simply, it’s the total amount of light that your plants are exposed to in a single day. Plants will have a specific DLI that they can handle based on genetics, environment, CO2 levels, etc.

No specific light cycle will save energy compared to another if the plants DLI is capped at a specific amount. Which it is. In veg I shoot for a DLI of about 40. I can get that with 600umol at 18/6. If I wanted to hit a DLI of 40 at 24 hours of light I would want them dimmed to 460umol. Both will give me the same DLI of 40.

I’m not entirely convinced that root growth is hindered in 24 hours of light. There are so many other variables at play. Environment and irrigation cycles can stimulate root growth more than light cycle. You can easily steer plants towards vegetative development with high frequency fertigation, proper deybacks over night, and VPD.

On top of all of that, root development is extremely high during the first weeks of flower when bud set occurs. If the plants are grown properly during stretch, you should be able to fill out a final 3-5 gallon container by week 4 of flower even if you transplanted from a solo cup on day of flip.

There are many ways to achieve the same result.

I have seen that kind of root stimulation before, pretty regularly if your root zone has many alive and healthy microbes. When everything is right you could fill a 3-5 gallon with roots in a week!

I don’t think it harms them per se but 24 hour light seems to stress them out a little bit. They have a happier vibe after a nap imho. Totally a preferential point I think but it’s fun to philosophize!

To bring the light cycle discussion back home to the original Bodhi topic...we had a plant or two of Black Light Fantasy that exploded in balls under non-stop light. Black Light Fantasy seems to have given her personal opinion on the matter. Other strains may be fine with it, but if you're growing BLF, maybe 24-0 isn't wise. It's something to consider if someone is reporting that a strain "herms". Maybe they're not growing it under the conditions that it was tested in. Are breeders testing for stability at 24 hours of continuous light? I doubt it.

I like 18/6 because It allows natural drybacks. Feed from hour 3 until hour 15, then have a solid 12 hour dryback to stimulate root development and improve node spacing.

That, and the dark period keeps me from working in the rooms at absurd hours. Forces me to take breaks and keep a healthy sleep schedule which is kinda important.

18/6 will be used in here!

Looks clean, what are you using for veg lighting in this setup?

Ha... I made that confusing. I meant "we" as in the Bodhi thread, which kinda meant you as it turns out. I forgot exactly which member had the situation that kicked off the light cycle discussion. Hope you get some great results from the BLF despite the weird behavior of those plants... I've been kinda regretting not grabbing a pack when it came around.
