Green Leaf Organics Posted June 28, 2015 Share Posted June 28, 2015 Most good garden stores stick it , may I ask why you looking for it? Also try aquarium shops as it's used as a water buffer in aquariums . Cheers Reaf Quote Link to comment Share on other sites More sharing options...
420SA Posted June 28, 2015 Author Share Posted June 28, 2015 Thanks bud. I see quite a few guys are suggesting it as a good source of calcium in your soil. Check out the video and the attached PDF. Both suggest using a bit of Oyster Shell. Also helps to buffer apparently. Thoughts? HowToBuildASoilArticle.pdf Quote Link to comment Share on other sites More sharing options...
Green Leaf Organics Posted June 28, 2015 Share Posted June 28, 2015 Lime works just as well if not better as a buffer and has a high amount of calcium and magnesium in it as well. Cheers Reaf Quote Link to comment Share on other sites More sharing options...
