  Hi, welcome back to Hydroponics Daily with me Dr.
• 0:03
  Russell Sharp and today we're going to cover another technique that could potentially
• 0:07
  be used to massively improve your yield and your crop quality,
• 0:14
  especially on people growing flowers, flower buds and where resin is important.
• 0:19
  And the topic today is girdling. So just like before when we talked about nicking
• 0:26
  and notching where you removed a section of the bark or the stem from plants
• 0:31
  to stimulate stem elongation.
• 0:32
  Today we're going to talk about girdling where you remove a whole strip from around the stem.
• 0:39
  Now what does this do? Well this limits the transport of sugars and hormones
• 0:46
  and other dissolved substances in the phloem sap down to the roots.
• 0:53
  It limits the plants, the roots then
• 0:56
  get starved of these sugars and
• 0:59
  assimilates and hormones now why would
• 1:02
  you want to do that you know we say we want a healthy root system
• 1:05
  well to a point once your
• 1:08
  plant has got into flowering and producing the the the
• 1:12
  harvestable crop in the flower buds really you
• 1:16
  want to make everything go into those flower buds or you want maximize resin
• 1:21
  and terpene and trichone production and things like this so you don't really
• 1:25
  need to keep on maintaining a healthy root system you've developed that through
• 1:30
  the vegetative phase and into the early stages of flowering that's what you then need the.
• 1:37
  Help you out you don't need to continue maintaining a
• 1:40
  great healthy root system so it doesn't matter if those
• 1:43
  root systems starts to falter fade away and eventually
• 1:46
  die off if you are if you're
• 1:49
  allowing those carbohydrates and hormones to stay in the
• 1:52
  in the upper sections of the plant so about 25
• 1:56
  years ago i was talking to a researcher and they were
• 1:59
  girdling cherry stems to to.
• 2:03
  See how that helped the cherries develop
• 2:06
  and they they were able to stop the cherries falling off the trees
• 2:09
  which is a big problem and it's called dune drop i
• 2:12
  think in cherry crops and they could increase the sugar content just
• 2:15
  by taking off a small ring of stem
• 2:19
  of bark from around the stem where the
• 2:21
  cherries were and that just stops auxin
• 2:25
  it stops the flow of sugars and eventually in a
• 2:28
  cherry tree that will that bark will grow back
• 2:31
  just just as the auxin builds up it'll stimulate
• 2:34
  callous formation and then eventually that'll join back
• 2:37
  up if it's a small section but if it's a plant that's
• 2:40
  going to die after you harvest that's never going to happen so
• 2:43
  I'm confident that this would be a really good technique
• 2:46
  I'm not aware of anyone who's tried girdling their
• 2:49
  plants but it's definitely something I would
• 2:52
  be doing if I was growing lots of plants I'd be experimenting on a
• 2:55
  few plants I might experiment with girdling just
• 2:58
  above the root to shoot junction so just where the stem.
• 3:01
  Is above the the soil or the
• 3:04
  growing media if you're in hydroponics and i'd
• 3:07
  experiment with girdling just below a
• 3:10
  flower node as well so every every flower
• 3:13
  but especially if you've got a big what they call colas or
• 3:16
  flower buds i would definitely girdle
• 3:19
  those sections of the plant and see if it
• 3:22
  had a positive and negative or no effect
• 3:25
  on the harvestable crop it's it's
• 3:28
  worth a try it could potentially massively increase
• 3:32
  your yield and quality so please try
• 3:35
  this and feed back any positive results if you've tried it already if you know
• 3:40
  if it works let me know maybe it's something that people have tried in the past
• 3:42
  and said it has no effect anyway that's been hydroponics daily for today girdling
• 3:47
  sounds like i'm saying gargling all right bye-bye that's enough for me.
