    Potash is needed in all stages of growth. Without it neither green nor bud growth will happen. MJ uses more of it then most plants too. The effect it has is that it allows plants to create new healthy cells, and it also keep those cells happy and desease free. It's N-P-K, N=nitrogen, P=Potasium, K=Potash, a good vegitative N-P-K would be 20-10-12 or something like that. A good flowering N-P-K would be 10-30-20.

    I hope this helps,

    I was told that 20-20-20 was optimal for flowering and maybe vegative growth. I could be wrong, but i clearly remember the numbers 20-20-20 for SOMETHING.
    Every post I make is purely fictional. Any information I have about cannabis is either through common sense or intensive reading. Any pictures posted by myself or anyone using my username are not my own and are in fact pictures I found on google images. I will not be held responsible for anything that I say on these forums.

    20-20-20 is not optimal for either vegging or flowering. It's great for you vegetable garden though.

    Look for a high first number(Nitrogen, N) for Veg, and a high middle number(Phosphate, P2O5) for flower. Some people like the 20-20-20 (Peter's brand) because of that high first number (nitrogen).

    In answer to your direct question though, Potash (K2O) is important for the formation of plant tissue and flowers, and it helps strengthen stem and leaf growth. Potassium acts as a general tonic and imparts increased vigour and disease resistance to plants.
