dolomite lime, which to use? ?

Is soil doctor pulverized lime ok to mix with happy frog soil to stabilize ph

Yep that stuff is perfect. Any pulverized or pelletized non-hydrated lime will do. 1tsp to 1TBSP per gallon of soil. Either way it won't start working for about a month so if you know you are going to run into pH issues with your soil, like with Happy Frog being it's a very low pH soil, top dress with lime as well and be sure to ph your water/fed in properly.

Thanks rancho! I justadded 5 tbs of pellet lime and 4 tsp of pulverized lime. Used the slurry method 3 cups of 6.8 ph water to 1 cup soil. Ph is 6.4. Should I add a tbs more of pulverized?? Sorry I'm a noob. But have researched a lot before starting my grow. Thanks again for your help!!
