thanks Zandor, Its funny how after asking a question how ya answered it yourself when ya ask it but there is always that uncertainty that that needs confirmation from a person who is experienced before one is able to accept the logic. Trying to limit the extent of my inquiries to just such queastion is not easy when , like me, your a newbie. Many many many more things to consider than I anticipated and I am barely moving into vegetation stage. lol Well looks like I am back to the hydro store for more Hydroton , stuff is $30 a bag ....yikes! I'm sure I am bound to be a nuisance long before I become profficient so expect to see a bit of me the next couple months lol
thanks, bill
