Rooting Cuttings / clones / cuts in hydroponics - part 3 · Hydroponics Daily

  Hi, welcome back to Hydroponics Daily. Today is the third day talking about
• 0:03
  cuttings and we're going to talk about hormones and hormone powders.
• 0:07
  So as I said before, auxin is a hormone that travels down from the apical meristem
• 0:12
  or bud down and it builds up at the bottom and that's where it signals to those
• 0:17
  cells at the bottom to form roots.
• 0:19
  And in most species that occurs naturally.
• 0:23
  However in some plants that are hard to root you might use a rooting hormone and these are.
• 0:29
  Normally powders or gels that contain a
• 0:33
  synthetic auxin so there's indole
• 0:37
  acetic acid iaa or indole butyric acid
• 0:40
  iba these are synthetic they're made in a factory
• 0:43
  they're synthetic hormones and you you dip
• 0:46
  your cutting in them and they are at the right concentration for
• 0:49
  your cuttings and then you quickly put
• 0:51
  them in the in the plug and then the environment and then
• 0:55
  they'll that will bypass this need for what's called
• 0:58
  auxinpolar transport down the stem
• 1:01
  and so that you
• 1:03
  get a far higher success rate if you use these routine hormones in in
• 1:06
  these species something like tomato there's no point because
• 1:10
  they they don't they require it the routine
• 1:13
  hormone or gel can also contain or traditionally used
• 1:16
  to contain a fungicide and this can help prevent loss
• 1:20
  of plants due to damping off and diseases like
• 1:24
  they're called water molds umicetes pythium and
• 1:28
  where all your cuttings just die from this horrible like
• 1:31
  algal type disease it's some people
• 1:34
  consider it a fungus but it's not a fungus and so routine
• 1:37
  powders and gels can help with that they contain a fungicide some people might
• 1:41
  not use try want to use it be very wary of products that say natural organic
• 1:47
  rooting hormone because they contain
• 1:50
  nothing but talc and a bit of seaweed extract maybe or even not that.
• 1:56
  They contain no hormone and they're just sort of like a placebo.
• 2:02
  So if you see an effect, you're like, wow, that really worked.
• 2:04
  But if you didn't see an effect, you're like, oh, wasn't I terrible?
• 2:07
  But actually it's the product that's just, it's just powder,
• 2:11
  powder, it's literally just powdered powder.
• 2:13
  So it could be like, you know, brick dust, even some of these retin hormones.
• 2:16
  So be careful of anything that's like labeled organic or natural.
• 2:20
  Always look for one with a synthetic hormone in, if you're
• 2:22
  going to take cuttings and you're struggling and then once you're you've you
• 2:26
  the problem with cuttings is you need to check whether they've they've
• 2:29
  formed roots or not and to do that
• 2:32
  you need to carefully take them out of the plugs and in the
• 2:36
  process of taking them out you can damage the delicate roots so you
• 2:39
  you want to sort of maybe sacrifice one or two and what
• 2:43
  you'll find is that before you
• 2:46
  get roots you get callus development which is like calluses
• 2:49
  on your hands a growth of indeterminate cells
• 2:52
  at the bottom the orcs in traveling down or right there has
• 2:55
  formed these calluses of just growth
• 2:58
  of of of cells and then that's the
• 3:01
  first thing you'll see and then slowly you'll start to see root primordia
• 3:04
  forming and then eventually you'll see roots
• 3:07
  and then once you start to see the roots you know that water's being taken up
• 3:11
  by the the young plant as it is now and you can start to drop the humidity down
• 3:18
  and you want to do this slowly in a process called weaning and you might want
• 3:22
  to increase the light levels, increase the air flow,
• 3:25
  remove the top of the container, or if they've got little.
• 3:29
  Vents slowly increase the vents every day because whilst
• 3:33
  it's in there in 100 humidity it's going
• 3:36
  to struggle to grow because 100 humidity is not conducive to
• 3:39
  plant growth low light is not conducive to plant growth and it's
• 3:43
  also going to increase your chances of getting a fungal disease and
• 3:46
  killing that plant or certainly reducing its yield so wean
• 3:50
  that plant as quickly as you can and then start going from
• 3:53
  just feeding it water to start feeding it an actual fertilizer in the water
• 3:59
  so gold leaf is perfect for that because it's already ph neutral it's a ph perfect
• 4:04
  and it's dechlorinated so that young delicate plant won't be harmed it's going
• 4:09
  to get all the nutrients it needs in the uk we call it liquid gold.
• 4:14
  And you'll increase that from say half a mil per liter up until as the plant
• 4:19
  grows through its life cycle to two to four mils per litre or whatever that
• 4:23
  is in fluid ounces per gallon in the US. Apologies, I don't know my imperial measurements.
• 4:29
  So that's cuttings and you can take hundreds of cuttings at a time.
• 4:34
  It's a nice enjoyable process. It's quite cathartic, meditative.
• 4:38
  You can put the radio on and I love taking cuttings.
• 4:42
  It's one of my favourite things to do you another tip
• 4:46
  is to get a pencil or a dibber and just
• 4:49
  dip a hole in the grow media before you put
• 4:53
  the cutting in that way you're not squashing the cutting you're not room and
• 4:56
  as you squash it in you can be the powdered rooting hormone can get brushed
• 5:00
  off so always dip it in and yeah you got any other tips or tricks for taking
• 5:07
  cuttings leave me a comment or an email give us a ring,
• 5:11
  always happy to speak to fellow growers that's been hydroponics for hydroponics
• 5:15
  daily for today thank you very much.
