Ahoy Captain D,
We will try.
From the picture I see Me Jas and the amount of product they sent you.
Methyl Jasmonate (MeJA) is an ester that is created when Jasmonate (JA) is combined with alcohol.
21 ml is equal to a bit over four teaspoons. That is a lot if it were straight JA. It has already been made into an ester and that is cool. Problem is we need to know the dilution ratio required for around 150 ppm. making one US gallon.
This ratio is critical. It must be disclosed from PG somewhere. Otherwise, we are kinda guessing at the dilution, and with these phytohormones, that is exactly what happened to Bruce Banner. AKA The Hulk!!!
I bought 20ml for $99 from Power Grown on Ebay.
It actually seemed to be cheaper than from their own website, though it is still them selling it.
I will pass some of it on to a couple of friends.
The advert says that it will make 80 to 100 gallons, so I assume undiluted.
Here's some of the blurb...
"
DiHydro Methyl Jasmonate is an oily liquid and mus be dissolved in alcohol or polysortbate 20 then added to water.best used at 100-150 ppm. 1/2 ml to one gallon of water will give you a 147ppm solution. Polysorbate 20 is recommended because it also is a wetting agent.
Dihydro Methyl Jasmonate is a substance used in plant defense.
It greatly increases tricomb and terpene production like no other product on the market. The results will astound you! "
These are the questions I emailed them. No answer as yet.
1. You say 0.5ml to 1 gallon. Is this a US gallon i.e. 3.8 litres?
2. I've also bought Polysorbate 20. How much Polysorbate 20 do I mix the 1ml Meja into before adding to the gallon of water? and is this best done by shaking it in a bottle?
3. What is the shelf life of the Di Hydro methyl Jasmonate that I bought and how should I store it?
4. What is the shelf life of methyl jasmonate once mixed into water?
4. When I apply as a foliar spray, do I apply to the under sides of leaves also or just the top sides of leaves and buds?
