  • Should I add lime to coir?

    Created by Anonymous on August 21, 2007 at 2:39 pm

    Would one of you nice gardeners out there please tell me if I need to add lime to coconut coir? If yes, how much? The reason I ask is it seemed like I had more vigor in my last crop when I grew in soil.

    Thank you very much,
    Bud

    Bud – Growcoir should be fairly neutral in pH so I can't imagine that you would need to add lime. It should be noted, that unlike soil, growcoir does not have any significant nutrient value to it. It's used primarily as a soil amendment or as a soiless growing media. Are you fertilizing with anything right now?

    Hey Bud!

    No need to add lime to growcoir, it’s got a nearly perfect pH balance as is! Soilless media mixes (like grocoir) are often void of nutrients, and are formulated to take heavier or prolonged nutrient feedings. Because of this, soilless mixes should be placed on a regular feeding schedule, making sure plants are receiving adequate amounts of plant macro and micro nutrients. Picking one nutrient line and following their recommended feeding schedule is one way to take the guesswork out of the equation. Aurora is an awesome, US based company that make a quick and easy starter pack for the beginner soilless grower. Check out the PDF link to their detailed feeding schedule. Find it here!
