So I have 10 clones that are just showing signs of root, and I want to prepare the soil for them the right way. I have, in the recent past, had issues with pH and Ca/Mg deficiencies, so I want to add lime to my soil before I plant, as I was advised to do. My mix is equal parts compost, vermiculite, and peat moss. I know that peat moss lowers pH. The directions on the lime bag are for normal soil, not acidic peat moss mix. Soooo..... how much lime should I add to my mix? I will likely be growing in 2.5-3 gal pots.... thanks a bundle! GTWT :XXhippylove:
Additional question along that subject. Is it ok to use hydrated horticultural lime in lieu of dolomitic ? Lime is lime, right ? As the hydrated lime is powdered , would the amount stay the same ? I am using about 2 cups per cubic foot of soil . Thanks Budz:anibong::anibong::anibong:
Ground limestone or dolomitic lime are generally cheapest, dolomitic contains Mg carbonate (aids in N uptake) and neither are as caustic as hydrated lime. Hydrated lime is stronger and reacts more quickly. I'd use a third less hydrated lime than ground or dolomitic in any mix. All three work for gardening but be a little more cautious when working with the hydrated lime. cheers
