Well you are apparently supposed to mix it in with the soil, and it takes a few months to fully neutralize and interact with the soil (the larger the pieces the longer this takes). I got the one that was called hydrated lime, and its like a powder, so its faster acting. I just mixed a TINY TINY bit in with some water, and it brought the ph up quite a bit. I watered it yesterday with this, then flushed with 6.8 water, and it came out in the low 6's, which is way better than when it was coming out low 5's. I checked it today, and the one that i did it too looks much happier than it did before, and I am about to do it to a few more. Luckily, it's time to transplant anyway, so I'm gonna mess with the soil before the plants go into it :thumbsup:

Hope this helped, peace!
