Usually I wait at least a week or 10 days for the any roots to heal to prevent rot. However, I find that with grittier mix you can start watering a bit earlier, since it doesn't retain water as long

Thank you

i sometimes water immediately after repotting :x i haven't had any problems yet . . . *knocks on wood*

I always water immediately after repotting. There is very little risk of rot with a gritty mix, and no sense in depriving a plant of water unnecessarily.

Can I add a related question? When do you start fertilizing (FP 9-3-6) after a repot into the gritty?

I actually skipped the bark altogether and repotted into a mixture of Turface and Gran-I-Grit, so have no nutrition at all in the soil. All the threads I've found so far indicate waiting a week or two, but wasn't sure if it was different with gritty.

I usually water right after re-potting, as well, with only a few exceptions....such as a Desert Rose that had significant roots removed.

Resume fertilization 1 - 2 weeks after re-potting.

Josh is right about exceptions. Any plant that has had thick, succulent roots removed (geophytes and such) should be given time to heal without water. But most plants I water immediately, even after heavy root pruning.

ej015, I use a similar 100% inorganic soil. I don't fertilize during the winter when plants are dormant. Though I have done so in the past. It doesn't hurt them, it's just unnecessary. I do fertilize at every watering when plants are in growth, and immediately after repotting as well.

Some master (and mistress) growers never fertilize at all, such is their soil nutritious. This however, is not achieved by using the famed-and-named gritty mix. To answer your first question, however, I wait a day or three - you can always mist the plant while the roots are healing in the soil after the repot.
