set in a large drain tray
 

Dear Ron, I am setting up a system where plants in rockwool are set in a large drain tray and my plan is to flood (w/drip emiters) and drain them and reusing the drained nutrient. my question is 1.) will this work? 2.) and how often do I flood per day? also do you know where I can get Dr.Chateliers formula? Thanks Jerry Gtk2@hotmail

1- yes
2- water several times a day
3- no
