Chitosan

[BillFarthing]

If you use 2 out of these 3, you may have sludge in your reservoir: silica, chitosan, fulvic acid.

Only Ornamental could probably enlighten us why, but in the mean time, don't do it!

I am really digging chitosan. I use it at .5 g./4L for a 125 ppm foliar. I have been using 1 g./gallon for ~290 ppm as a drench. I like to hit them a week before flip and the week before using a bud hardener. No loss in yeild and the frostiest nugs I have seen!

 

[Only Ornamental]

Chitosan is a positively charged polymer whilst fulvic acid has several negative charges and hence the two interact and precipitate. It's a common incompatibility. What silica does depends on the used form but it tends to precipitate with quite a few things.

We should rename Only Ornamental Candyman. He always shows up when you say his name. I just hope you don't have a hook for a hand!

Anecdotally, I am showing a yield decrease if I go over ~500 ppm for drench. It's the frostiest stuff I've ever seen, but I think there is a ceiling to the benefits of adding more chitosan.

Only if you say his name three times in a row while dancing counter-clock wise around a bowel .

Thanks for sharing your observations. I was always rather sceptic regarding those publications which didn't show a plateau or some sort of trade-off. Any other stimulant either stimulates growth or defence (aka 'frost' if you like) but not both such as, allegedly, chitosan.

EDIT: Shit, we just realised that we spoke of him in third person. Something's wrong with us/me/him LoL.

Are there any interactions with chitosan and various forms of pH up and down?

How about hypochlorous acid?

 

[Kygiacomo!!!]

Im trying a new product this year that is called opti veg. its got 8.2% chitin in it.
Oh yea OO is a legend! im learnt so much stuff from his posts,well that parts that i could understand

Only if you use way too much pH up... but then your plants are screwed anyway.
Citric and phytic acid might cause gelling at higher concentrations of acid and chitosan.

chitosnot if you add it too soon to nutes, i always added it last to my mixes

Wise words .

Is it safe / beneficial to use chitosan as a root drench in constant low levels throughout the entire life of the plant? I've only used it as a supplement every couple weeks. GreenLeaf MegaCrop incorporates it into their nutrient mix, is the reason I ask...

Why, yes it is. I'm using 1 tsp./5 gallons of chitosan oligosaccharide all through flower.

Considering that there's 1 ppm of silica in Megacrop at 1.0 EC, I don't think you have anything to be worried about with overdosing on chitosan in the bag.

Application of Chitosan oligosaccharide in agriculture

Application of Chitosan oligosaccharide in agriculture

Chitosan oligosaccharide is a low-molecular-weight product obtained by degradation of chitosan by lactate which has outstanding water-solubility and high biological activity, thus it can be easily absorbed and utilized by crops.

What’s advantages of Chitosan oligosaccharide
1.Increase seed germination
It has the good effect on seed germination,after we applying on rye grass seed,its germination index increased 33.5% and vitality index increased 59.5%.

2.Increase plant resistance ability
Help crops improve anti-stress ability and disease resistance,increase crop tolerance to environmental stress such as drought, low temperature ,early frost.Increase root system develop and increase lateral roots number. And stimulate the resistance to soil borne disease including root-knot nematode.

3.Promote the growth of stems and leavesInduce plant resistance
Strengthen photosynthesis,increase photosynthetic rate and efficiency.After applying Chitosan oligosaccharide,The bine is erect, brawny, much more ramose , division department expand. Tall plant height, fat leaves and thick stalk.

4.Induce plant resistance
After applying chitosan oligosaccharide,by activating a plant’s immune system,it can maximize plant’s resistance ability.

Basic Chitosan Recipe

I use this recipe only once in flowering at week 3 or 4

recipe is for 5 gallons of nutrient solution containing roughly 500ppm of Chitosan
you can't measure the added 500ppm with EC meters

You need:
-50 - 55 ml of 1 to 1,5% citric or acetic acid
-10 - 11 grams chitosan powder
-distilled water (RO should work too)

typically you use 5ml of 1,5% acid for 1g of chitosan

Step 1: Make 1,5% citric acid by diluting it using any diluting chart depending of the strenght. In my case I used citric acid 30%. I diluted it to 3% at first (10ml citric acid 30% and 90ml distilled water) then 100ml 3% citric acid and 100ml distilled water resulting in 1,5% citric acid. Since i only use 50-55ml i stored the remaining 1,5% solution.

Step 2: Weigh 10-11 grams of chitosan powder and add the 50 - 55ml 1,5% citric acid to it. Stir gently and set aside for about 30 minutes.

30 mins later

Step 3: In a measuring cup fill in 450ml of distilled water and add the (creamy) chitosan acid mixture and stir well.
Usually it should be continually stirred for 2 hours but stirring it every other 15minutes for about 2h worked fine for me.

In my case it never really dissolved completely. Everytime i returned to stir again it settled down at the bottom of the cup.

Add the 500ml Chitosan solution to your 5 gallons of nutrient solution
pH the solution and water immediately


Be careful when using drippers or automatic irrigation and flush the system with just a small amount of nutrient solution NOT containing any chitosan afterwards.

nice one King,
please tell us your observations the following days after the application,
and wouldnt a foliar spray be more effective?
thanks

 

[King Rat]

I'll upload pictures one day before application and a few days after.

I was feeding them the chitosan today and noticed i never posted that recipe before.

i dunno if foliar feeding the chitosan is more effective but since i feed them chitosan only once and only when they have set the first flowers sprays are out of question for me because of the residues it would leave.

Benefits from foliar spaying chitosan: it will induce the SAR almost instantly also it would be enough just spraying 2-3 leaves and it work for the whole plant.

I still don't like to spray stuff once in flower.

Chitosan is feeding the microbes in the rootzone, keeps rootzone clean of pests and induce SAR just like foliar feeding.
The benefits of fighting off pests, bugs and powdery mildew is because of the plants reaction to chitosan and not because of residual chitosan on foliage as some might guess.

One time at band camp I ordered chitosan O direct.

Overall it wasn't very expensive for a kilo, however if you use lobster or any sort of sea compost it's redundant. So it doesn't really do anything. I suppose if I didnt use lobster compost and local cow and lobster compost it might benefit them.

You want that oligosaccharide in the soil. The tissue can only do so much

 

[kalopatchkid]

Has anyone done a side by side with chitoson O. vs without?



The new chitosan O I got off ebay doesnt have the same smell as the first one I purchased....it really doesnt have any smell, but I used it twice on my current run and all my flowers are looking pretty caked. The first time I bought it, it had a vinegary smell.
