Thanks Mr. Clandestine, that makes sense, now you said a soil flush...is this something you HAVE to do? or just for Ph testing purposes? if so would one just drill a hole or 2 on the bottom of the pot to do this, then just pour about a gallon or 2 depending on the size of pot and let it run out and test that water? if i am correct... also is it wise to have rocks on the bottom of the pot?
I have read a few things online etc but it never fails that something contradicts what I read so this is why I ask

thanks again everyone!
