Hi everyone! I'm pretty new to hydroponics but have read several books and most all the information available on the internet. I'm just about ready to start growing, but am waiting on seeds and me growlight to arrive in the mail. The only questions i can think of now are about ph meters and growing mediums.

I would like to use grow rocks for my medium as i am using an ebb and flow system (ovbiously). What i was wondering is how i should transplant seedlings into a medium such as grow rocks. will it be alright if i get a vermiculite/perlite mix into the system if its in the center surrounded by growrocks? i am kinda afraid the prelite and vermiculite will wash away from the rock medium and into my reserviour with flooding and whatnot...

The second questiuon is about inexpensive pH meters with two solid bars. I have recently bought one and am wondering: Can I just let it sit in my reserviour and not take it out and clean the tips or not? Id like to be able to check pH at a glance.


Thanks guys!
