  Hi, welcome back to the Hydroponics Daily. Today's topic is a general overview
• 0:04
  of what is a biostimulant and some examples of some biostimulants.
• 0:09
  So biostimulants are an additive to a crop that stimulates growth or improves
• 0:18
  yield that's not down to nutritional effect.
• 0:22
  So they are not pesticides, they don't kill any pest diseases,
• 0:27
  weeds, they're not synthetic growth regulators they all
• 0:30
  come under pesticide regulations and they're
• 0:33
  not fertilizers because they're not the primary aim is not to
• 0:36
  add a specific nutrient essential nutrients so
• 0:40
  they are basically like a a vitamin
• 0:44
  or things like this that stimulate the growth of
• 0:47
  the plants in a non-nutritional way so examples conclude
• 0:51
  seaweed extracts amino acids beneficial
• 0:55
  microbes so a living organism or
• 0:59
  so a fungus or a bacteria humic acids
• 1:02
  which are extracted from a certain type of brown coal
• 1:05
  or humic material phosphites which are a type of phosphorus chemical that doesn't
• 1:11
  actually work in it doesn't actually it's not a nutritional form of phosphorus
• 1:16
  but stimulates root growth triacontanol that's a fatty alcohol extracted from
• 1:20
  beeswax or the leaf surface of certain plants.
• 1:24
  Chitosan, that's a solubilised form of what is the chemical that's in all insect
• 1:30
  pests or fungal cell walls.
• 1:33
  So a solubilised version of chitin, it's chitosan, and yucca extract,
• 1:37
  that's a very popular biostimulant.
• 1:39
  So these all have actions that are non-nutritional in their main aim.
• 1:45
  So something like an amino acid like glycine will stimulate root growth and
• 1:52
  tryptophan will stimulate auxin production a microbe might stimulate or eat
• 1:58
  ethylene the acc the precursor to ethylene.
• 2:02
  Yucca extract might open up the grow media. Chitosan might stimulate defence responses.
• 2:07
  Humic acids might help with the absorption of nutrients, things like that.
• 2:11
  So there's loads of different modes of actions for biostimulants. There's not just one.
• 2:15
  We're going to do a different... Each one of these biostimulants will be a topic
• 2:20
  for Hydroponics Daily in and of itself.
• 2:23
  So don't worry, I've glazed over. I've just given you a fly past for all of these types.
• 2:29
  But the main point to say is they're not pesticides, they're not fertilisers.
• 2:32
  They're not in feeds like Goldleaf per se.
• 2:36
  If they did, they'd be a mucky mess, but you can add them to your feed.
• 2:41
  So all of these additives work really well with Goldleaf, or if you're in the UK, Liquid Gold.
• 2:49
  And they can improve your yields beyond what's achieved with nutrients alone.
• 2:54
  So definitely recommend you looking into them. There are some good ones, there are some bad ones.
• 2:58
  And for every single one that's on here there
• 3:01
  are good versions and bad versions and i will go into great detail about
• 3:05
  which ones are the good ones which ones are the bad ones and what to look for and what
• 3:08
  to avoid so things like seaweed extract i've
• 3:11
  produced millions of liters of seaweed extract in over the years as as a manufacturer
• 3:19
  of biostimulants so i know my onions when it comes to biostimulants if you go
• 3:23
  if you research biostimulants and what to look for in a biostimulant you might
• 3:27
  find one of my articles on this subject.
• 3:29
  So check out Biostimulants. Thank you very much.
