Harvesting and Flushing - Questions
    #346209 - 01/12/10 06:42 AM (6 years, 10 months ago)

Hi everyone,

Well I'm approaching 8 weeks and my skunk plant looks pretty awesome. :smile:

In regards to flushing, when should I start? I'm currently 51 days and flowering time for this strain is said to be around 56. Should begin flushing after I hit 8 weeks or now?

Also, in regards to harvesting - should I be harvesting the top part of the plant to let more light through to the lower buds which are in the process of maturing? Or should I harvest the whole thing in one go, sometime next week?

I'd start the flushing now.

indeed, start flushing now.

also, the bottom of the plant matures faster than the top, so while your logic is sound your methodology is backwards. I usually just chop the whole plant in one go however :shrug:

plain water for a final flush, solution to fix problems if you want to (plain water works for that too).

Really?  In all of my years I have never noticed the bottom half to be as mature as the top half when harvesting...

My lower buds are usually just as trichome laden, yet the density lacks and the hairs have yet to turn.  I know it's not a light penetration problem because all of these past results I have gotten were OD in sunny locations.

I don't think any amount of wattage HPS will penetrate as well as the big Halide in the sky.

haha you are right about that, the sun is the end all be all of lighting :lol:

I wonder what the difference is though, the hairs on the bottom always turn for me first.... sure the density lacks, but I don't attribute that to not being ready, just them not being dominant growth points on the plant

well the bottom of the plant is older than the top.  seeing as it was spit out first.  Plus the main fan leaves with 3 blades are more potent than the middle of the plant with a 9 bladed fan leaf.

Seeing as the plant is symetrical,  the top is pretty much a mirror image of the bottom.

no, not really. they all have growth tips.

please tell me you don't smoke fan leaves....

this confuses me most out of your entire post. isn't this a direct contradiction with what you said in the first part?

im talking mostly about how the plant prioritizes its nutrients.  The top is most potent because its the main growth tip.  And the bottom because CO2 is heavier then the air around it thus sinking to the bottom and being more readily absorbed at the lower level.  Although it is not considered a nutrient its vital to the growth of any plant.  Im sure you already knew that though.......  And who in their right mind would smoke a fan leaf?!

My amount of posts dont directly determine my knowledge on the subject.  Thank Yu

If your grow room is setup properly air is getting circulating around, and co2 concentrations are the same throughout.  Even beyond that, show me a study that indicates lower buds being more potent and I will believe your statement.

The reasoning your giving us doesn't really sound very likely to me.  The plant moves resources around, and does not focus on the lower portions.  Even if your having a higher concentration of co2 on the lower parts or your plant, it is still getting less light therefore inhibiting how much co2 that part of the plant can be using at any given time.

http://www.greenmanspage.com/guides/thcpotency.html

#3 states that the smaller the leaf, the more potential potency it contains.  So the growth point coming from that smaller leaf would obtain the same properties because the leaf is directly connected with that growing tip.  Hence the smaller the leaf, usually the top and the bottom ones the greater the potency of the connected growing tip.

I trust every word the writer of this site says.

Lol, sure you can write that.  But it gives no explanation whatsoever as to why.


He also states this

"Stems. Same order as leaves. The smaller the stem (twig), the higher the possible concentration of cannabinoids. Stems over 1/16" in diameter contain only traces of cannabinoids and are not worth smoking. The small stems that bear the flowers can be quite potent."


Personally I wont load up a bowl of stems.

This is also hilarious.  What he is stating is that the leaves connected to the bud are the most potent.  Not the lower ones on the plant.  Pay attention.


Leaves (a) that accompany flowers (small); (b) along branches (medium);(c) along main stem (large).
Generally, the smaller the leaf is, the more potent it can be.


And again no backing for this.

Strain is also a determining factor to this.  Actually a large part.

                        plant 1        plant 2        plant 3
Position on plant        (SP5)          (SP5)        (UNC 335)
~~~~~~~~~~~~~~~~~        ~~~~~~~        ~~~~~~~        ~~~~~~~~
TOP        % THC          6.1            6.9            4.8
          dry wt (mg)      35            21              28
MIDDLE    % THC          3.0            5.5            3.1
          dry wt (mg)    119            74              70
BOTTOM    % THC          0.8            4.0            1.5
          dry wt (mg)    314            133            133

[top:mid:bot ratios      8:4:1        1.7:1.4:1        3:2:1

Now these are only 3 different strains conducted in this study.  Neither one of them were of any strains containing kush, widow, skunk, god bud etc. which would have an even greater, more uniform thc content.

1 and 2 were actually the same strain containing completely different ratios of thc content.

So lets just say that theres many determining factors to a plants potency...

..and i can site the writings conducted in these tests as well.  Which contains many scientific studies.

So by your graph the top and middle are the most potent, not the bottom or smallest leaves.


This is derailing your thread Spency.  Sorry.  To answer your question I would just chop the whole thing down at once.

that's all we're asking for. peer reviewed literature backed by established knowledge within the field of botany.

I apologize for any offense, I was simply looking for clarification of your point.
Quote:

:lol: this should not be a concern for cannabis. who in their right mind has air so stagnant in their growing area that CO2 can actually accumulate?

I assumed you smoke fan leafs because you're talking about the potency of fan leaves. I guess my question here is why on earth do you give two shits about the potency of fan leaves?

i was simply referring to the growth tips from said fan leafs.  But since the 60's weed has gotten far more potent with cross breeding and isolating that most studies are obsolete anyway.  My strain is god bud and it has a uniform thc content throughout. 

Now random ditch weed would have a staggering decline the further down the plant.

Sorry we got off subject and hopefully this taught a few people something tho.

good night

It seems to vary from strain to strain. I've read several guides telling me to just chop bud sites when they're ripe, not a all in one go thing. I think it's called power harvesting or something like that - idea is I guess you pic each individual site when it has reached it's maximum potential. That does seem like a lot of work for me. I only really was wondering about this stuff because I'm finding it hard not to "sample" it every day. :tongue: So I figured perhaps I should do the power harvest thing if I'm already smoking from it daily.

Also, Harry that's interesting that your lower buds mature before your top ones. The hairs on the lower buds, as well as the trichromes which I've looked at under my little "handy-dandy-hand-held-microscope" are definitely not as mature as the top ones.  :shrug:

I must say though, your last grow was unusually awesome - so it's not so hard to believe that perhaps you just had unusual plants. :tongue:

Flushing has now begun!
