Will seeds still mature in very cold weather, or could i bring them inside?

[quokka]

Hello,

I have a question for some experienced seed makers.

I have a plant pollinated with seeds starting to form but still small and green, and the weather is getting very cold.

I am wondering if it would be best to leave them growing outside, or if it would be ok to bring them inside under a vegging light that is 20h on/ 4h off.

Will the seeds survive and keep forming in below zero temperature or would they be better inside? I wonder if the change in light hours would stress the seeds someway?

Thanks.

They won't develop below 5-10°C night temperature if it's above 10°C for northern strains and likely higher ones for most others. Take them inside. In my limited experience forming seeds will still develop properly when the plants are put back to veg although a flowering light schedule will be better, the seeds will get more energy and grow faster and bigger.
Too cold can lead to sterile seeds of seed abortion; I've experienced that early this year with Finola although this is the industrial hemp most suited for cold climate.

Thanks OO,

I have seen that seeds do form properly when taken from outside and put under a veg light, but i was wondering if the change from flowering to veg hours would affect the sex or cause herm problems?

Thanks again.

Every sort of stress could cause 'herm' problems if the plant has the predisposition for it but does that really matter? Have I understood correctly that all you want to do is let the plant finish its seed development? If so and the plant would hermie on you and pollinate itself, those seeds will ripen later than the ones already there = no problems . Okay, the fact that the plant could hermie may be unfortunate but if the plant has the predisposition anyway... it wouldn't go away only because you're not forcing the trait to show itself.

I was meaning could the stress cause herm problems within the seeds being created?

I know the plant might show some male flowers when it starts to reveg, but that's ok.

i would be worried the plant will stop focussing on seeds and more on re-vegging with the light on 20 hrs. jmo.

I guess what i'm asking is, can the genetics being created inside the seed be affected by the change of light hours?

 

[Only Ornamental]

Nope, very-very unlikely. I see no reason why the offspring should change.

Thanks OO,

That is good news.

The plant i have has 2 very different spectrums of smell, from a very sour-sweet raspberry liquorice to a type of spice, very unusual combination.

I pollinated it with a very similar looking male from the same seeds, but let him die.
My mistake.

 

[Only Ornamental]

Why did you take a similar looking male and not a similar smelling one? Just wondering...

 

[quokka]

Well i only had 8 or 9 seeds, and these 2 were similar looking, short with jagged edged leafs, and the rest of them were taller with smoother leafs......

I didn't know that the mother would be something i wanted to keep, so it was just chance that i even kept the similar looking male.

I might upload some pictures tomorrow.

I can't say that it is elite, but i can't get clones, so i am happy with it for just now.

Besides, why don't you take it inside just for the night or if you're not going to smoke it put it under some CFLs 12/12? They don't need as much light to produce mature seeds as they do for decent sinsemilla buds.

In general the plants need enough time to continue birthing the seed, and enough light to have the energy to keep growing.

I haven't tried shifting plants from a 12/12 cycle to a 20/4 cycle. I think they will keep trying to make the seeds, and you will get some seeds ... but that's a guess.

If you can spare a light, and keep the plants-with-seeds-forming on the same cycle as they were outdoors - except warmer & indoors - I think that would be better for your seeds.

The genetics of seeds already formed won't change. I don't see how they possibly could. If seeds are you primary goal, you have options. Cover the plant at night. Bring the plant in at night. Bring the plant in under lights, regardless of the day length.

Having been pollinated, the plant will create viable seed if conditions allow for it. I don't think that long day length is a condition preventing that at all.

OTOH, I have no experience with the situation you describe & might just be dead wrong.

Thanks for the replies, i appreciate it.

I didn't really doubt that the seeds would form if i brought them inside, i was more concerned that they could be genetically weird somehow, but it sounds like it should be ok.
