When to Flower Outside

Recommended Posts

I was looking at the charts, in the middle of September it gets down to 12 hour days.

I don't think I can make it that long.

I started late so as to grow a Natural Summer Grow, that's my theory.

Flowering in the wrong season has caused lots of problems around here.

I should be good if I can make it to middle of August or so and drop the lights.

I just have regular led bulbs supplementing  18/6 to keep them out of flower.

 

When do you do outdoor flower?

When do you do outdoor flower?

 

I have been thinking about this lately, because I grow in sub-tropics, where middle of summer is about not quite 14/10.

A lot of places we see "Plants need 12 hrs darkness to flower."

But, if you think about it, this is obviously and clearly not true at all!

E.g. take a strain given as 8 wk flower indoors or late September finish outdoors.

Well, if it only started to flower on the equinox, Sep 21, then it finishes in 1-2 weeks?

No, it obviously doesn't start flowering then.

And if you count back 8 weeks from end of September, let's say start of August, how much light?

So I did some checks with various time zones and strain information.

Seems to be that counting back the total flowering time from harvest,

for most temperate climates, then it is about when light cycles are 13:40 / 11:20 light / dark.

In a lot of places, that is maybe late July or early August.

 

For me, middle of summer is almost exactly this daylight length.

And I know that photo plants will pretty much flower straight away, if they are mature / old enough.

 

Back to your question, "When to flower?"

For now, just leave them naturally outside.

They'll keep vegging until early August or so (I don't know your longitude...).

And start flowering when on a bit less than 14/10.

Different strains will certainly vary...

this is why equatorial sativas go for months, because light isn't their critical factor...

I may be wrong, but I don't think plants *need 12/12 to flower. It's the increase in the amount of darkness that triggers it.

I have some start to flower outdoor in July

Mid July with 9hrs of darkness.

That said, I have a Swazi that won't start flowering until September 1st at the earliest. So that's about 13/11.

Where I live we can plant in February most years.

That's all fine but when the plants are big but the light is not for flower, they go in and out of flower and you get stretchy buds.

I wait until June to start my grow so as to do a natural Summer grow and fit in with the natural lighting.

I still use lights in the evening and morning to ensure no early flowering.

I think I already answer this for you.

The gradual decrease in the amount of light will trigger your plants to flower. Get rid of your supplemented lighting June 1st and your plants will be ready. 

If you are *really worried, you can start covering them up to put them in darkness 12 hours a day starting August 1st.

In your location, if you're having trouble with bud structure, change your genetics.

Ya, when I grew with lights I ran 18-6, don't like 24hours of light, I think they need a period of darkness.

Then we cut down to 12-12 for flower.

There's no problem with flowering. Problem is they go into flower as soon as you put them outside.

So we fight to keep them veg. False flower causes lots of problems.

When you start too early your plants get big and time to flower. If you have to wait for a month for proper light what happens to the plants? They go ape shit.

I go all natural light but I put some led bulbs around to lengthen the day, hour of two morning and night to keep them in flower.

I have friends who enforce darkness but that's too much work for me, I can't cover and uncover the grow twice a day.

We seem to have it working pretty well but always room for improvement.

Adding a lot more to the beds this year to get them ready for Summer.

I used to sometimes put a cut in my yard for the outdoor growing season when I lived in the Carolinas. They usually started flowering by late July, which is much less darkness than 12/12.

I have heard that this is related to the far red light that outdoor plants are hit with each evening, which makes up for the shorter dark hours.
