Muriate of potash (Potassium chloride) 0-0-62

[Buds Bundy]

Noticed today someone is trying to sell a 0-0-62 product and it reminded me of a product a few years ago called Dr K from Rambridge wholesale I think or maybe Commercial Lighting. You were suppose to use it the last few weeks of flowering to swell up the flowers. I know it worked because the people I got it for said the flower did swell/got hard but there's wasn't any real difference in weight wise. Only thing I could figure is the plant retained more water/swelled and when you dried it it all evaporated lol.

Has anyone tried it or say Potassium Sulphate (Sulphate of Potash) since seems Potassium Chloride can kill beneficial microbes in soil although SOP can lower soil ph (real soil not sure about inert media like Peat/Coco)

I've looked on the Rambridge site and its not listed anymore or the Commercial Lighting site.

make potassium carbonate. chloride will release chlorine as the plant consumes the potassium, it won`t absorb all the chlorine, excess will be released. Kills good microbes.

sulfate would be better than chloride but where are you going to get magnesium easy?


I guess I should make a potassium carbonate formula for you organic growers. basically, just burn a super hot pile of wood and let the ashes soak in a tub of water and in the sun, churn it up, give it an air-stone. wait a week.. I can do a whole years worth of potassium fertilizer with burning one-yard pile and leeching off the good stuff to dry. produces about a pound of potassium carbonate, free. prob 0-0-20 or so

I just got some potassium chloride, to go along with the calcium and magnesium chlorides. As I understand it the chlorides flush out not biding to soil. But mostly to use as a foliar spray. I use Langbeinite when making up the new soil for sulfur.

I thought Langbenite was 0-0-22, pure K.

It's 1 potassium sulfate and 2 magnesium sulfate
