Newbie question: which brand of orchid mix is good for phalaenopsis

[Hmmm15]

Hello folks,

I need to repot my phal from grocery store pretty soon, as I can see lots yellow roots from its clear container.

I try to avoid mixing stuff myself (though it will probably benefit my plant most), since it requires quite some efforts.

I google a bit online, lots ppl recommend Schultz orchid mix. However I couldn't find it from homedepot nor Walmart amazon is out of stock also. Is this product discontinued?

Can someone please recommend some ready to go mixture that are good for phal ?

Thanks a lot!
