does quality of night period matter

[wibe]

I've successfully initiated flower and am not using a tent in legal Canada indoors..

I have heard people claim anything but pitch black night periods will herm your crop but i'm sure that's up to genetics because in nature it's pretty rare to be sheltered from moonlight.

thought I'd ask though.

will darker nights help in any way or so long as you aren't stressing or herming your ladies it's all good?

[Mr.furley]

Pitch black! No light!
Moon light is a reflection of its former self and does not carry candle Watts, take a Lux meter outside in the full moon.

Nature is natural to a plant it's what it knows, you are creating a natural environment under artificial conditions and dim lights, light leaks, and especially cell phone lights in dark period Will cause big problems down the road.

I bumped my time and for two (2) nights my girls got a wakeup before I found it, I'm pushing two (2) extar weeks of flower and have nanners on one plant all because a little mistake at the wrong time.

What he said! I had a plant hermie on me cuz I opened the door of my grow box when the lights were off.

[alltatup]

Yes, I know that.

My outside green house grow had light from spot lights and I had no issues but inside one grow I had an led light put me back in veg ,four times same grow different reasons all had to do with light leaks I ended up using the whole grow for oil , total dark go in your tent and close it up fix whatever light leaks you have

I have heard people claim anything but pitch black night periods will herm your crop but i'm sure that's up to genetics because in nature it's pretty rare to be sheltered from moonlight.

Honestly most hermies are not genetic and are caused by stressing the plant. Yes you need to block all light. I have had pinhole and zipper leaks reveg my plants and caused some to hermie. It's not a problem until it's a problem but when it happens it can ruin an entire crop. Having experienced it first hand i dont take chances anymore.

Hi Wibe...I haven't experienced this, but I've read that absolute darkness is required at all times while the plants are in flower. They respond to different types of light along the light spectrum. Even just a few seconds of the wrong kind of light during the dark periods of flower will cause the plant to revert to veg, or maybe even over stress and go hermie. Hope everything goes well.

Yup my last grow did the samething I told my wife the tyiniest leak will hermie my plants she said you are exaggerating I’m sure it takes more than that and then the nanners came this time around she is making sure we don’t make the same mistake. I let her doit just so she can see for herself cus I couldn’t convince her.

Welcome to the darkside, lol
It's best not to disturb the darkeness!

That said: with photo's
I have had full light switch come on for 2 hours, in the middle of the night for 3 nights (before I noticed) with no ill effects.
I have left the grow lights on, all night without ill effects.
I routinely, left the bottom tent windows open with no ill effects.

These days, I just plant auto's.
One less thing to worry about!

I have heard a friend had a light leak from a door vent ....and the plants closest to that door did hermie.

[wibe]

hey thanks for all the great replies..

i'm growing in a room off a hallway that gets no light.

the plants are in a nook of the room also so even any bouncing light from the rest of the house would have a long way to illuminate the ladies.

with the recent full moon i covered over two small windows that may have leaked that natural illumination as well as possibly distant (1/8 mile away) street lights.

if i walk in to tuck them in it's pitch black until my eyes adjust and even then i'm stumbling if i left some stuff out of place on the floor (even sober :> )

Check out one of those GREEN LED head worn lights. Plants don't mind the green, it has 3 levels or brightness and a flashing mode... The first level is plenty to see and even read stuff in the dark

A Quality grow tent is worth its weight in hermaphrodites grows.

[wibe]

too much unzippinmg for me an i suspect i'll get bored of this hobby inside of 5-6 grows anyways.

i'll likely stick to a few outdoor strains anually though they look great along side some heirloom squash and brussel sprouts.

so as long as you dont herm tho no other proven benefit to zero light? i just noticed some small led's in the room like on chargers and a gigabit switch.

despite them being far from illuminating the "growing nook" i'll take precautions and cover up..no harm (or herm heh) yet so upward and onward.

[Rwise]

I had a single red led on just 1 power strip I missed, fox tails is what it caused here,,,,

I honestly feel like re veg or hermi happens is because of the 12/12 light cycle. Yes it works but plant is barely in flower mode and then one little leak sends it into veg or hermi. In nature the nights get longer. Cannabis is a short day long night flowering plant.

[Cali]

Cloud yup 13 on 11 off a bit better for me to make sure they got they’re 12. So start with 12 and add an hour that should doit and more towards the end.

[Farmall]

So in playing the devils advocate, how do we know that 12 is the magic number and that 13 on wins? It’s an interesting idea and I’ve never come across that thought. Seeing that the 18/6 and 12/12 was always just presented as gospel
