I just picked up a box of it and don't know a whole lot about it, except that it's hot (0*0*60).
Anyone use it? How much?

TIA

The only thing I ever use this for....
I live where it rarely freezes, or even frosts- maybe once every 3-4 years. Consequently I have a lot of tropical plants who are very delicate where cooler temperatures come into play, some of the very rare palms I have paid $300-400 for. I am a simple working girl- I sacrificed to be able to buy these things- needless to say, I want to protect them.
Potassium is known to strengthen the cell walls in plants. Every fall I spread some around... maybe one cup for a 6 foot palm cluster.
The theory is that as the water inside each cell reaches freezing temperatures, a stronger cell wall will resist rupture, and the plant more likely to survive without damage.
This recommendation comes via a Palm Society.... I have no other knowledge for any use of straight potassium.
Below is Cyrtostachys renda- sealing wax, or lipstick palm.

Delta

it

use it

every day, almost

150-275ppm range

supplemental or direct

potassium sulfate

great stuff

3hounds,
I'm aware of the benefits of MOP in helping plants in cold weather. Rare palms huh, cool! Thx.

Delta,
How have you been? I asked about you via K1 just last night.
OK, what I have is derived from potassium chloride. Another concern. Chlorine (CI) Max...60%.
Anyone know how to apply this to a soil grow? One cup seems high for mj indoors, no?
What is the difference in K chloride & K sulfate?
I've had about a tsp soaking in a gal of water. I'm thinking (..Run!! ) that I would just add some of the diluted solution to my regular feedings. One thing I do know is that I want to raise the K ratio in my feedings. I tried a 9*10*15 with a supplemental N (almost burnt them once). Best growth so far. Also found some tri phosphate. Ideally, I would eventually like to mix my own n*p*k & n. atlantic kelp..seaweed, whatever, as long as it's n.a. cold water. Should be readily avail. in England etc.

tia,

ps Delta, your format gave me a flashback

organic

I am going to start using Sulfate of Potash (potassium sulfate) or Sul-Po-Mag (sulfate of potassium magnesia) on my berry fields this year. Certain forms of these are considered organic, but most of them have been chemically broken down to make them more plant-available. The source is a mined mineral called langbeinite; sul-po-mag is the rawest form and rates at 0-0-22 (22% K20, 11% Mg (18% MgO) and 22% S) while the sulfate of potash usually runs at 0-0-50 and is probably broken down from the langbeinite. Both are soluble.

If you have worries about Cl, the potassium sulfate often will come with guaranteed levels of 2% or less.

Thanks zzoom ... I've been well and around finishing up that salt thread and even coming up with a few crazy new ideas.

Potassium Chloride can be used, too, as a solute. It's very potent. BUT, I find many strains of 'bis are not tolerant of high levels of chlorine. So, you may want to be careful with it, imo.

Potassium Sulfate, or, like Organic said, the Sul-Po-Mag. These are my perferences, as well (K2O, not KCl). They are more 'natural' in origin and readily available, as well. Hence the tage 'potassium sulfate' ...

{... you are getting SLEEPY ...}

Oh, and I wouldn't add KCl directly to the medium. It's way too soluble and will most likely burn then leach. Go for a lower grade if you plan on using it in a medium and a higher grade for mixing in with fertigation routines...

Muriate of Potash depends on the manufacturer and comes in a wide variety of products. It can be kind of confusing, as they are all basically the same things (K20 or KCl) the difference is in the tracel elements and solubility. And, of course, the percentage of chlorine. Regardless, there are:

All right, there. So which is it?

i used murate of potash (0-0-60) by Hi-Yield brand, i put in 1/4 teaspoon per gallon, my plant seems to be doing great, very dark green healty, cept at the very tips and very small amount of yellow has appeared, duno if it's from too much potash er what, it's hasn't spread so maybe it's nothing.
hope this helps

sulphate

another box of sh....would aquarium chlorine neutralizer do anything to this? Or how about a cup or two in the compost pile?

zmy

butterbeen

i got some of this stuff a weak ago i also need some info on this murate of potash 0/0/60 hy yield. if u use 1 tsp per gallon then how much would u use to poor out the gallon into a 15 gallon dwc in flowering stage with outer rawsalts also to be add

stonedazian

hey butterbean i would not use 1 tsb per gallon with the hi-yield brand, probally end up burning your babes, i put 1/4 teaspoon per gallon in my mix, peace
