Hey all, I have my zamaldelica still popping whites at 18 weeks. Is this normal? Seems really long but it is getting pretty cold atm' maybe slowing the flowering? I also cut a little a couple weeks back, so it was bit early. Good but not the super strong I was hoping. Is there a 'sweet spot' for harvesting the within it's strongest expression? One yellow nanna also showed up but I picked and no further have returned. Regardless, it's been a real joy to grow just getting a little impatient! haha. Thanks comrades....

How do you figure? I though these went longer depending on the individual if they are really only 11 weeks I am gonna pop these soon with the OTpurple Haze for fall. They are gonna bloom starting August hopefully.....
What do you mean with "how do you figure"?
If you mean how I'd found out: the one and only Dubi told me. Tons of respect to that guy. If you ask me, it's impossible to overestimate him, 'cos he's a living pure sativa encyclopedia. Of course he also knows a whole about indica's as well.

12/12 is only a general rule for cannabis. Generally, everything is flowering by the equinox.
11 day / 13 night will always be faster to finish than 12 day / 12 night. Simulating longer night hours (similar to after the equinox) will encourage faster flowering. 10D/14N will flower faster than 11D/13N and so on.
Some purer sativas (ultra thin leaf) will require 11/13 to finish as they are from parts of the world where 12/12 is the norm for a good portion of the year and not the signal to seal off / end flowering. Switching these purer sativas to 10/14 will speed things along even further.
Some indicas (especially high latitude acclimatized indicas) can be flowered successfully under 13D/11N (and some even 14D/10N!) because they're used to exceptionally long daylight hours. These plants will take slightly longer to flower (as compared to 12/12) under 13D/11N as they will still think that its before the equinox and therefore theres no real hurry to finish off as its still late summer.
It should also be noted that the increase in speed will tend to lessen bud size to a minimal degree as the plant is hurrying itself to finish before what it expects to be winter.

Long flowering plants I grow always get chopped with new growth
there. My game is after a hundred days the plant ebbs a little
then pushes more calyx a few days after that.
I chop after the second ebb, around 110 days.

Flowering and lighting period
Flowering and lighting period
Fascinating stuff. In regards to day/night fractions affecting flowering speed and duration - Does anyone know if it is viable to initiate flowering with short day cycle like 10D/14N, and then back it off to a more energy providing cycle like 11D/13N... Or would any increase of light period length trigger the plant to back off flowering, or other unwanted effects such as an increased likelihood of hermaphroditism?
In-other-words is there a single light period threshold for each strain or plant where as long as you stayed under that length of time flowering would progress relatively unabated?

Ed Rosenthall (as well as many others) has played around with light cycles and there are several schools of thought on whats best. Every plant will have a different lighting threshold depending on where its from, how well acclimated to the growing area it is and so on.
Vegetative
Ed suggests running 24/0 in veg because the plant doesn't care and it speeds vegetative along because in veg the plant is focused on growth. I disagree here, I believe the plants need a bit of sleep as my 24/0 runs have always left the plants looking more stressed, so I run 20/4 in an effort to decrease the stress. I consider 24 hours of light a bit like running at 110% all the time.
Transition
Several people (mainly those concerned about light cycle stress causing herms) believe in a more natural switch from veg to flower. As an example, a week at 18/6, a week at 16/8, a week at 14/10, and finally a week at 12/12. This more accurately replicate the flowering process outdoors. There are a couple things to consider with this method:
- The plant will continue to veg until its hits its minimum photoperiod for flowering, which means you'll need a lot of space for veg as the plant is going to stretch when its getting closer to minimum photoperiod.
- The daylight length that you're trying to mimic (solstice to equinox) happens over the course of 12 weeks, not 4 weeks - so the plant is still being stressed, but to a lesser degree.
- You can't run perpetual setups with lighting changes as it will goof up your other plants. The work around here is multiple chambers for each day length, but you'll need additional space / lighting / etc.
Flowering
Generally, you'll want to decrease time during flowering to match the natural falloff of daylight hours going into winter. I've never done this, I go from 20/4 one day to 11/13 the next and don't ever have issues.
Starting short (10D/14N) and going back to (11D/13N or 12D/12N) is a great way to lengthen internodal space later in flowering. The plant will stretch a bit less initially, but the switch a couple weeks later means you're starting to make it seem like the plant is coming out of winter and into early spring which can lead to airy buds.
If you're trying to control stretch, don't rely on day length - run blue lights (5000k / 6500k). Red light tends to make for bigger buds but the plants tend to stretch more. Blue light adds frost and decreases stretch at a minor (probably 5-10%) decrease in bud size.
Terpene & Tangwena -
Wow - great stuff. I am presently run 6500Ks for the first 2-3 weeks of flower to control the stretch as you (Terpene) suggested, but I have not yet run a control to see the extent of the effect on any particular strain.
You guys are just an unending wealth of info and I want to relay my thanks to you all for the assistance of making this pursuit such a pleasure. There are a handful of you that I trust to always have interesting and insightful commentary, and as I scan through threads I always stop to absorb more thoroughly when your avatars scroll by.
This is such an expansive hobby - such a large pallete for experimentation!

I'd give her some time, the leaves might thin out a lot.
Unfortunately I did'nt take any pics of mine when they were that small so I don't have anything to compare yours to, but it might be a bit on the malawi side.
I also have the feeling that a lot is down to growing conditions, I often have the impression that my plants have wider leaves than most of the pics I see from the same strains on here.
ZD
N
not real geroi
Dont think about what pheno it is at this stage. Sometimes i have wider leaves at this stage and finally its narrow thin when its monster...its long flowering and buds are important for recognizing so dont be unpatient , its longer flowering
mine were wide a bit also and caused a little confusion but ended all good. have some new ones coming up now. one is pretty thin, the other is wider. had some last night and it was the best smoke i have ever had - this was after i thought i screwed up the harvest etc...leaving the rest for a long cure....woo hoo.
