What do you think of 24/0 for the light?

[AutoWonders]

The problem with the C3 argument is that the observed gains

My old mass built led lights with 3 watt and 5 watt diodes did better with 24/7 lighting. I proved that to my self long ago. It really comes down to each their own. Had I not changed to Autocobs and Quantum lights I would still be growing with a 24/7 lighting schedule.

Just 2 comments from me before bed.
1) I've had and seen better results where VPD is low( ideal zone)...compared to blasting plants with 1000000 watts

2) The cost of the PAR meter will be saved in properly using DLI.
Actually save you electricity .

I have the 240w kingbrite led in the tent and was planning to do 24/0 but I have read a few people recommending not doing 24/0. What do you think? Would 22/2 or 20/4 or 18/6 be better or do you think if I can keep the temperature in the tent right that 24/0 would be the best to do on there?

Personally I have found it depends on your light. With my HPS it did not seem to like the full 24 hours. Leaves would start to droop around 20 hours. With my led of half the watts I have been able to get away with 24/0 but havent seen enough of a difference to leave it. Just my experience messing around.

22/2 or 20/4 are my favorites to use for led.

I've been super baked in quarantine and been reading more about the circadian rhythm of plants. I've added a few blurbs in parenthesis of my own.



Now give this some food for thought:



So if this is the case, the circadian rhythm (basic internal clock that it says "okay, this is what my normal routine should be, let's see how it goes") of plants (including ruderalis and ruderalis hybrids) may be (suggested by the article above) regulated by sugar levels (brix) in plants in the time keeping schedule of the rhythm.

So another factor may be (to complicate things further) the brix level of the plants themselves, not just in proper nutrition/feeding of the plant, but having high/proper sugar levels to properly regulate plant function.



Where is @JM ? That guy can talk high brix all day.

good timing!

Here you go:



Staying safe so far.. to all my AFN peeps!

And YES.. BRIX level... micronutrient levels... is sOOO critical.. nutrients need to be balanced.. remember the biochemical sequence of nutrition in plants:

Also... no indoors for a looong time now.. but.. When I did.. with HPS.. I found 18/6 was the best.. but when I used LED 20/4 did better.

I had a veteran grower tell me awhile back that he found best results with autos running them 24/0 for first 40 days, and then 20/4 for the rest of the grow. He said he found that once they get into flower, the extra 4 hours with 24/0 doesn't make any difference, so he back them off at day 40 to 20/4. I gave this a shot, and its worked well for me, especially in winter months when I need to keep temps up during seedling/early veg stages. The Mephisto team runs theirs at 24/0, and Daz runs his at 20/4.

That actually makes a lot of sense! Thanks for sharing!

For years, I've had successful perpetual grows using 12/12 in my bloom tent after 24/0 under T5HO for a month...way back when, I'd run a photo alongside my autos...found I was happy with results. Running a combo of qb, cobs, and blurple at approx. 50w/sq ft, I've found that some autos are finishing a bit earlier.
What I wish to say is.....there are no rules about light schedules which seems to be a complicated comment to most new growers....12/12 does well for those of us who just wanna grow weed, not impress anyone except ourselves.
