What time of the day do you run your lights?

image.jpg image.jpg My lights just turned on for the evening. I like running cold 50s air in from outside at night. It is running in flower on 11 on and 13 off. They turn on at 8pm and turn off at 7am. It's a new light schedule that will decrease every two weeks until 9 weeks harvest. I had a friend who does a lot commercially for an edible company tell me to do it. Buds are already getting bigger from 36 hours of darkness I just put them through from changing over from a 12/12 schedule between 10pm and 10am

Your guy is hurting your yield. DLI, or Daily Light Interval, can be thought of as the total tally of photons your plants get in a given 24 hour period, which takes into account both duration and intensity.

Simply put, the more light, the better, up to the point of saturation- which isn't happening in too many indoor grows because it's extremely expensive. Therefore, a grower wants to get every minute of lights on time s/he can.

Running a schedule of less than 12 hours of light through early and mid bloom is unnecessary and counterproductive in terms of encouraging plant growth. Only in the last weeks does it make much sense to shorten overall day length.

Many people run 13 hours on, knowing their plants will flower with 11 hours of darkness. Still others are experimenting with far red LED lighting at lights out to encourage the night response, all to add another hour of daylight.

And this goes for abnormally long periods of darkness at the beginning or the end of bloom, as well.
 
7p - 7a perpetually here. If my plants arent big I run 600w at first then switch to 1000w for that pod later.

My friend, I mean this in the nicest way possible; the commercial scale mmj growing business is not a settled science, and size of op is no guarantee of best practices.

In addition, it's important to understand that the very difference of scale means that what works for each of you is likely to be very different.

Best of luck.

OP. This guy knows his shit hard! Ttystikk grows monsters!!

For me my veg tent light kicks in at 6pm - 12pm and flower 6pm to 6am.
 
I run a flip schedule (NOT the silly box, though); things flip around 1am and 1pm. I highly recommend this sort of schedule for larger growers, as it means you can reduce your design cooling capacity by half and run it 24/7. The best way to do this is with water cooling, which is also efficient enough to pay for itself on its own merits.
 
Regardless of time, 18/6, 20/4, 24/0, 12/12, 13/11, etc... check your pricing of electricity through the power company to see the non-demand hours which is usually the cheapest times to run lights and see if you can fit it into your schedule to save a few bucks, if it works great, if not so be it... just my two cents... and two cents adds up over time...:mrgreen:

I use to run them at night but now that I'm retired I run from 5 AM to 5 PM and I don't grow in the summer any more. The reason for these hours is that I'm awake and paying attention to the plant's environment. When they go to sleep I so do I. Also if I want to put a plant outside for any reason I can since I live in a warm climate especially the spring time. I only do the 11 hour thing in the last week of flower.
 
For flowering On 7pm, Off 7:30 am, besides being cooler it's the lowest rate period from my hydro service provider and gives me some evening garden time. For veg I run 20/4, On 4:00 pm, Off 12:00 pm...
