Northern Lights #5 vegitation period

How long should I keep Northern Light #5 in veg state (18/6) before going 12/12 to get the best bud?

Depends on how tall you want your plants. Expect them to double or triple in height once flowering is induced.

But what do you think is the best height for NL #5 before going to flowering or how many weeks before going 12/12 would you suggest to keep them in veg state?

After reading a bit about NL #5, it looks like they only get to be about 2-3 feet tall. Maybe veg until 10-12 inches before starting 12.

To get the best bud possilble...nothing beats letting the plant get to preflower, that's when she's telling you that she is mature enough to start the flowering cycle. I grow all my plants like that if i grow from seed. Once preflower stage is set...it's only a matter of days before you see bud starting, infact my one plant is on day 5 of flowering and i have white hairs EVERYWHERE, and it's already starting to get "sticky", which means the sugar production is already underway (tricomes in development). After 5 days most people don't have anything when they induce flowering...so weigh out the options...if height is a problem, there are several techniques which you can use to control the height restriction, some common ones being LST, topping and "FIM".

Good luck with your grow!:joint::mrgreen:

Northern Lights, triple in size? No way, NL is a short strain, it always has been, that's why it's genetics have been used in so many indoor strain, you'll be lucky if it doubles in size when you flower it, depending on where you got your seeds. (Some may be further hybridized NL and some may be the 'real' NL#5)

letting the plant get to preflower, that's when she's telling you that she is mature
Totally agree when growing from seed. (Clones will likely be sexually mature when taken)

Cheers.

P.S - From germination of seed, it takes an average of 6 weeks for a plant to pre-flower, and thus be sexually mature, some do it in as little as 4 weeks (some maybe even less), and some may take 8 weeks or longer to pre-flower, however it is unlikely any NL#5 would take that long to show sex, I'd guess 5-6 weeks to show pre-flowers.

Yes green is mostly right...on average a plant SHOULD be at preflower stage by the time it's 8 weeks old...and yes some shorter some longer...my babies all took 5 weeks to show perflowers, and for you rookies out there...that's 3 weeks seedling stage and 2 weeks veg.

I can let it grow for 8 weeks before going to 12/12. How can you tell if the plant is showing pre-flower?
One of my plants is shorter than the others (it is the oldest). Does it matter?
They all look happy and healthy.
Do I have to do anything to make the shorter one reach the height of the others?

Female preflowers are 2 little white hairs that will appear in the internode above the leaf stem, and males have balls.

The height is mostly determined by genetic, different phenotypes amongst one strain show different characteristics, the more hybridized the strain is, and the less stabilized it is, the more likely it is that more variation will show between phenotypes. Other than that, if some of the taller plants were at some stage in low light conditions, they may have stretched to gain more light, thus making them taller. Usually if a plant has stretched for light, it will have longer internodes than the others (internodes being the space between 2 nodes *See Glossary of Terms in my signature for more info on these things if need be), but once again, the length of the internodes is partially determined by the plants genetics, thus, different phenotypes may have different length internodes even if they're grown in the exact same conditions.

Pre-Flowers

As for the pre-flowers, they look like this:
Picture 1: Female pre-flower. (I know the two hairs coming from the calyx are hard to see in the picture, but look closely, the two white hairs are their).
Picture 2: Male pre-flower.




Hope this helps a bit, cheers.

Thanks for your help and the pictures.Now, i know what to look for.
But what if not all 5 plants show the pre-flowering sign at the same time?
If one or two show the male or female sign, can I go 12/12 or can I still wait for the rest to mature?

Yes, you can start 12/12 if they're not all showing sex yet.
Tru.

And if you want to wait for them to all pre-flower before going 12/12 you can do that too. When they show pre-flowers, it's the plant telling you it's sexually mature, it doesn't mean it has to flower right then and there, you can wait as long as you want after a plant pre-flowers before you switch to 12/12

Thanks for all the information you gave me. Now, I feel a lot more confident and I know what to look for.

Wonder why I cant see the pictures?
