Why would defoliation increase stretch rate

Well seriously boys I take clippings from house plants to thin and let new growth come along all the time. With Tomato plant suckers are removed. As well as any branches that do not have fruit. That is so that the nutrients go straight to the fruit not areas where it is lot needed. Now I don't know much about defoliation and whether it produces bigger or better yields or not. But it does make sense to me.

I still dont know why they are stretching more. Lol. So I should just strip the branches completely then?

What is your ventilation and heat like? in a poorly vented box/room the plant will stretch. Heat will stretch them as well. Too much heat will stunt it before killing it.

I have read that he was talking about outdoor grows. Along with soil, whereas indoor and hydro systems are ideal for strips. Outdoor, just let stretch to whatever
I've watched Jorges vids and I don't doubt he knows some stuff but he is far from thee authority on growing.

Each grow is unique to what environmental factors you have in place. I have a SCROG in a box and I pretty much need to prune and defoliate some or it will be an unproductive mess. If I grew outside, Maybe I wouldn't cut anything.

i can't believe you even wasted the peoples time posting some shit like that.

stretch is in the genetics. unless you use something like Phosphoload (funny how this supplement was made to that prevent or slow down stretch and yet your studies says it promotes it), Gravity, BushMaster etc, or training techniques that i stated in an earlier post, your plants will stretch. how much? it all depends on the genetic makeup of the variety that is in question.
Yeah why would i waste time with a UNIVERSITY study. Keep loading up on bloom foods.

Because PGR's are completely different. Why would YOU waste any ones time spouting off shit you think you know about, when in reality you have no clue wtf you are talking about.

PGR=high phosphorus plant nutrients now? What a crock of shit.

Phosphoload, when applied correctly, will effectively halt the vertical growth of a plant and create more lateral growth, as well as larger bulkier flowers with a larger overall yield (up to 30%) and less overall time to maturity. The active ingredient in Phosphoload is Paclobutrazol, which is a plant growth regulator (PGR). Paclobutrazol will interfere with the flow of Gibberellins throughout the plant (a hormone responsible for much of the plants apical growth.. One

Paclobutrazol (PBZ) is a plant growth retardant and triazole fungicide. It is a known antagonist of the plant hormone gibberellin. It acts by inhibiting gibberellin biosynthesis, reducing internodial growth to give stouter stems, increasing root growth, causing early fruitset and increasing seedset in plants such as tomato[SUP][1][/SUP] and pepper.[SUP][2][/SUP] PBZ has also been shown to reduce frost sensitivity in plants.

Of course stretch is PART of the genetic makeup of the plant, but adding HIGH bloom nutrients with out of WACK NPK ratios can cause your plants to stretch even more. Learn how to read, and comprehend, know it all.

MJ boards are full of people like you, acting like you know more about botany then guys that have dedicated their whole lives to studying it. I think I will take the botanists word over yours ANY DAY of the week. Because they actually back up their FACTS with controlled group studies and published work.

Please do not confuse defoliation with pruning which is often necessary especially with indoor crops to provide for proper ventilation to prevent mold.
Exactly what I was going to say. :)

I think a lot of people are confusing defoliation and pruning on these threads. There obviously are people defoliating their plants, which I personally think is a tad insane, but I see quite a few people defending "defoliation" while they describe "pruning" in their examples.

Pruning is basic & moderate trimming of a plant. Defoliating is massive leaf removal.

I don't get it. If defoliation is the shit when it comes to growing weed, then why, after the grasshoppers ate all the leaves off of my plants outdoors did I end up with no harvest? According to most people here I should of had a record harvest.

For every study you can find about defoliating certain plants such as cotton to increase yield, you can find the another one on a different plant that reduces yield, seed and oil production (cucumbers...sun flowers etc...) The real issue here is there haven't been CONTROLLED studies under the exact same environmental conditions. There are a ton of factors in play here, like how much leaf area was removed, at what time during the plants growth cycle it was removed, etc.

Just from personal experience having tried pulling off fan leaves, the best yeilds I have ever seen in my garden are from keeping the plants healthy and leaves on the whole way through.

Until I see an actual scientific case study done on the plant under controlled conditions, that actually proves defoliating a cannabis plant increases yield, I will keep my fan leaves on.

I am the complete opposite of Jorge, I use indoor hydro. But a lot of his info has helped me. I don't JUST follow Jorge, you guys have helped me a lot so far also. All growers help other growers by sharing knowledge and experiences (good and bad ones).

Even my lower fan leaves get light, so I am wondering why would I cut them off and make the plant focus on healing while it is in bud?

And I am no expert but it seems like cutting fan leaves off the main stem would tell the plant it needs to grow more, and thus stretch to make room for more nodes.

I agree with this, ive been researching defoliation since it keeps coming up over and over again and I believe that there is some merit to it in the right circumstances, however until I know for sure that it would produce a bigger yield im very reluctant to try it myself as it goes against all common sense

no, stop confusing what you don't know what with you actually know, while trying to make it seem like i don't know what i've seen and experimented with my own eyes.
fact, an indica or very indica dominant plant will not stretch that much, no matter what you feed it and vise versa for a sativa or sativa dominate plant. so once again, what was your point?

nice little spiel you put together, but still doesn't negate my point that it's a bloom fert that was made to prevent stretch and not the other way around. you sound good to some, but not all.

another fact that i see that you forgot to mention, is that Paclobutrazol has also been show to induce flowering at a faster rate(which essentially makes it a bloom fert, npk ratio .3-0.7-0.1, flower dragon 0- 0.15- 0.30 etc) which explains why you chose to leave it out. you remind me of one those types that take what he needs (to prove his point) and leave out the rest.

it sounds as if you were speaking to yourself when you wrote this.

fact, science or botany isn't always correct or exact as you tend to think or tend to make us believe. i've seen too many instances where science or botany didn't advise many years ago or yesteryear for that matter, but highly recommend it in this very day of age. see where i am going Jr.

for instance, let you and botany tell it, once bloom was induced, one was to switch from veg ferts to bloom ferts. now of days, it's highly recommended that one continue to use veg ferts for the first 2-3 wks of bloom (it was proven that plants benefitted and were healthier from steady doses of N in med to high dosages for first 3rd of bloom) then switching over bloom ferts. however, let you tell it, the botanist from yesteryear, the science of today falls short to the science of yesteryear, lol.

like i said, stretch is all in the genes. if you're worried about stretch, i would suggest pinching the mains, lst'ing, topping or putting them in at a certain height to combat such an issue.

imo, you guys are both right, stretch has to do with genetics and nutrient feedings. whats the fucking problem here?

thanks fresh2death, posted a very easy to understand breakdown on why and when to prune (source vs sink). thanks for that.
