Question for experienced outdoor grower

Hey guys. So my ladies are doing lovely, but my concern is. Since they were planted in January and they still got about a month of flowering. Well the days are getting longer and it's gonna throw my plants off of the 12/12 schedule. Will this interfere with my plants even if they're almost ready to harvest?

Interfere ? It could, if there's a month to go.

Some strains could react worse than others, but adding light hours when flowering could confuse them and larf up your yield or other undesirable mutations. Nobody likes a confused pot plant.

Might want to look into covering them and keep their hours regulated. You'll be happier if you keep them making sticky trichomy juice, not veg leaves or boy parts.

So basically move them out from direct sunlight after 12hrs? Can I just put them in the shade?

You could try that, but they might still "see" daylight, even if it's not as intense as direct sunlight.

If there's any way you could cover them, so that they experience darkness I'd feel safer.

Generally a flowering plant in nature experiences DECREASING hours of light, not INCREASING.


You might try checking out some light deprivation threads etc. Good luck.

ya u need to cover them,darkness if no like roy said they get weird on ya 12-dark 12-lite if u in north hem,day are increaceing 2-3 min aday

Let's be clear 12/12 really has nothing to do with it. It's picky I know, but it's true. It's an indoor light schedule in wide use which ensures enough dark period to induce flowering in most photosensitive strains.

What I'm saying is, as long as there is still enough dark period to stay within the flowering threshold of your particular strain or pheno of strain, regardless of increasing daylight, the plant should continue to flower. I'm just speculating here, but it could possibly stress some particularly sensitive and hermi prone strains to maybe throw a nanner or 10, but again just supposition.

So can I just cover them with a tarp at 7:30pm everyday till its dark out? Just to be safe

Yup. What you brought up makes sense, but not knowing his strains genetic proclivities, and how long he has to go to finish , I'd say covering them is the safest plan.

If he's venturesome, he could try covering some and leaving the others out, and see what they do.

I like that idea. Always learning man.

You don't even have to cover them the entire night. Put the tarp on a for couple hours in the evening and take it off before bed once it gets dark, that way the plants aren't sitting in a humid environment all night.

How long are your days? {How far north are you, in other words?} And how long do they need to go? You need at least 10 1/2- 11 hours of night to keep them from flipping to veg.

Covering late in the afternoon is about the best way to lengthen the night. Are they in pots in your yard? That would make it easier than in a natural setting.

Knowing the genetic makeup and flowering tendencies of what's growing would be helpful.

It's also worth mentioning that a covered plant may get some condensation settling in (mold alert !!! ) so paying attention to how they're covered etc. is important.

If they're covered in the afternoon it's sometimes easier for a persons schedule, but it can create more condensation as the temperature shifts downward at night and if the cover is put directly on the plant, rather than allowing some air space it could be a mold invitation. Stay safe.

I'm way down in the south actually. Texas. So 7:30 am sunrise 7:50 pm sunset with the days getting longer. I already have something set up for light deprivation, I just put it on at 7:30 pm till the sun sets. So it seems to be doing fine so far. I will keep updating @Larry {the} Gardener

@Rob Roy shit bro out of the twenty some plants I got I only know what one of them is and that's a purple og kush. It's still a seedling

Happy sampling to you. Peace.

I light depo every year,but I move mine inside each night,10 gal pot do pretty good harvest in july

Not at all I had plants finish flowering under 15hrs of sun, ur over thinking it. You've got nothing to worry about

I'm covering my plants that are about to be done. Just to be sure, but I do have some plants that just started flowering so I'm gonna leave those uncovered. Just because of their position it's gonna be too difficult to cover, but hey. At the end at least I'll learn something new for next grow. Which is coming soon. I'm trying to keep a steady cycle going year round.
