Title

Oyster Shell Flour A high quality soil conditioner which consists of 96% calcium carbonate and many micronutrients, Oyster Shell provides a long-lasting, steady release of nutrients to help regulate pH levels, improve fertilizer uptake, promote healthy cellular structure and enhance soil tilth. Oyster Shell is also helpful in creating more active habitats for soil microbes in compost piles and worm bins.

This product is not what it would appear from the name, i.e. it's not a product made from crushed oyster shells but rather it's a particular oyster shell mined from the San Francisco Bay from ancient sea deposits made up of very tiny and fragile oyster shells.

Replacement for dolomite lime?

I would never use dolomite lime ever again, i did it once and ruined all 6 and i didnt add as much as people say. Poor drainage overdosed on mag, never again. This time i used the oyster shell flour and that brang my ph up growing in peat based soil. After about 3 weeks with peat soil the ph drops, i grow organic but if the soil ph is off its just like synthetic you will have ph issues. Put some oyster shell flour in when going into last transplant before flowering and you will see a difference in everything.
