Can you buy sts already made up ready to use, or would I have to make it?
You would have to mix it.
I just looked at the link
@Ryno_nuggs posted the price seems a little high for the amount .
I bought my chemicals for $70 CAD the down side was it cost me $70 CAD to ship it to my house.
If I was closer to Toronto I could have walked in and bought it off the shelf but that's a 4 hour drive (it would have cost me more for gas to get there and back)
on the bright side I have enough for the rest of my life!
The concentrates will last for 6 months or more if stored properly, once mixed your good for a month.
I mix 100 ml concentrates of sodium thiosulfate and silver nitrate.
When I'm ready to reverse a plant I mix 5 ml of each concentrate with 90 ml distilled water and 1 drop of dish soap (help it stick to plant)
My 1 batch of concentrates will make a total of 2 liters the link Ryno provided will make just under 1 liter.
That is why I find it a little expensive, because each 100 ml silver nitrate concentrate I make only uses 0.1 grams and the smallest container I could get was 25 grams.
I have enough to make 250 batches @ 2 liters per batch that's 500 liters, So my total $140 chemicals and shipping works out to 28 cents per liter.
keep in mind I mix 100 ml at a time which is enough to reverse a plant so I will get 5000 reversals lol.
Like I said enough for my life time and then some!
If you look at that another way my first batch of seeds I made, I got about 300 seeds (went overboard on pollenating) with the price of seeds
my first run paid for the chemicals and then some.
