Effects of defoliation during flowering

Harvest76,

I have mainlined for a few years, and have since switched back to LST.
It's faster and doesn't require constant plant recovery.
The canopy uniformity and yield I suppose made it say 15% more advantageous in the flower phase once harvested.
However, given the extra work, electricity etc, I can save 3 weeks easy just by manipulating via LST.

I suggest trying it though, because it really does improve your understanding of the plants development.

Happy Growing!
Thanks! I appreciate that input. I like LST, it's simple and non-invasive.

Day before I flip and day 21. Yeh to do a proper side by side with only defol in week 1 vs wk1 and 3. Havnt had any success with removing sugar leaves though , and finishing time won't change, but bud development will. They will finish with smaller buds. I'm starting to think it's really strain dependent. Greengenes strips his back hard but they always come back well developed
 
I defoliate somewhere between day 14-21. If I'm trying to control stretch or the canopy is just too full I like to go around day 14. But if I'm not too crowded I wait til day 21 because it seems like they don't grow back in as quick and leaves those bud sites exposed longer.

I've never had plants finish slower from it and it def helps with lower bud production and in turn overall yield.
What you see for effects when you defoliate at day 14 of flower?
I am right now in day 14 and the canopy is over full!! Like a jungel
Plants are super healthy (praying)
I am worry that it be to much stress to defoliate now....

If you can upload a picture, but yes I have defoliated that early before. Depends on how overgrown it is but I'd try to only take part of them.

Well at this stage your getting a fair bit of light down to those leaves so I personally would leave them until they get more shaded then you know they won't be contributing anything to the plant but rather just sinking nutrients into it. I've played around with defol at different stages and lately my best results have been no defol, just taking big hand size fan leafs off. Pulling leaves off stunted the growth and whilst it finished within the correct time frame the bud development was sub par compared to the non defol group. It also depends how crazy you let it grow if you scrog. If you have colas going up right next to each other and hundreds of them the leaves will literally cover the whole plant and you will only see the tops and buds when they start to develop will be banging against each other causing humidity spikes, mold and sticking to each other. If you cut away the thinner straggling ones to free up some of the internal space in the canopy the air within helps the leaves transpire and the system works better overall giving you some very nice and consistent bud development true to the genetics. My 2c

I had a mate come round toward the end of my first grow and he said straight away I plucked too many fan leaves (thought I was doing the righty for light penetration) and he suggested taking only the really intrusive leaves that are blocking heaps of light in veg then 1x defoliation in the first week of flower and no more than 20% so will have a crack like that this time and see how we go

I am amused when people think they know more about plants than evolution.
Read up on the inverse square law. It is counterintuitive to remove the engines of your plant (fan leaves) to expose smaller leaves further away from the light. Here, l'll help

Inverse Square Law basically states that the farther away an indoor grow light source is, the less effect it has on an object, and this formula is geometrical in its diminishing effect. As an example, a quality indoor grow light that is positioned five feet above the plant canopy is 50% less powerful at that height.

Growing outdoors under natural light is a different animal. Defoliation is not as necessary. As well, defoliation also allows better airflow through the canopy. In general, there is plenty of scientific and anecdotal evidence that defoliation of varying amounts can be beneficial to an indoor grow. Massive indoor commercial operations wouldnt do it if it was harmful to their bottom line.

That's a beautiful picture. Been wanting to try this for a while now

I hate the debate. And I'm outcast for my methods. I lollipop indoors and remain removing mature leaves until the last week or two. It adds a week or 2 to finish, But buds are dense and hand grenade size.

Outdoor I practice heavy defol until week 5 or 6 of flower. No science to back it up. Just buds and nature combating depredation for eons.

Choose your method by seeing what works best for you. Most issues are improper plant health. Not defol or stress related. Wish more people understood this. Peace and bigger buds.

Omg, this is next level funny...

When you remove a fan leaf, which on an evolutionary theme happens often and the plant has entire biological systems designed to react to which do zero harm when understood, (big breath) your plant goes through an entire process in which its grows more , gasp, leaves...

This process is, within optimal conditions, an automatic response by your plant because its also an idoit. Within this process your plant creates growth hormones that benefit and can work synergistically with certian growth periods in flower.

Timing your defoilation to illicit a specific resposne by your plant is why defoilation works to increase yeild and terpene profile.

Lazy fucks its LST

Long story shorter , you never have to defoilated as long as your happy with getting less

A bit yuppie but correct. There is a method to the insanity. Why I pinch and not cut. LOL.

Stupid responses will get meet with hostilty...i made it as easy to understand as possible...i am not a botanist
I totally agree. No offense.
Although a stupid response may be a question in earnest. Our basics are advanced bio chemistry and plant biology to many. KISS.

Trying to maintain comprehension levels for all interested.

The more successful growers.....The soon it is truly legal.
