i dont know if another thread have been put together like this but i wanted to know about alternative amendments to help with ph.
First i know dolomite lime is used by many, i seen a lot of mixes that add dolomite lime to ther media.
But i wanted to know, does any buddy have experience using other ph buffering amendments??
i have used oyster shell lime, dolomite lime and im thinking of using gypsum in a few runs.
IMO i think they all pretty much work the same, except i was advised by a highly respected horticulturist to switch to gypsum because if applied at the right amount 2-3 TBSP to a gallon, that the ph will stay in a range for great plant growth..??
he didnt give me a exact number on were the ph will be buffered too but explained that its a chicken and egg thing, saying that the microbe life in organic soil are in control of ph and gypsum gives them what they need to keep the ph between 5.5-7.5?
that was his explanation, by the way he grows all kinds of container plants that require all kinds of different ranges of ph.
to him gypsum is the best,
so what do you guys think, is dolomite lime over rated.
is it the only rock dust that works on buffering ph for growing pot?
has any one experimented or experienced any good results or bad results when using alternatives to dolomite lime?
and if so can you please explain the rate or % you used to your soil or soilless mix..
i used both dolomite lime and oystershell @ 2 tbsp per gallon to peat based mixes.
ill be running coco this run and im advised to use only 1 tbsp to the gal..
so lets here it
