Need help/advice on ebb and flow with clay balls! Please help!
Ok so I'm trying to take Grizzman's advice and just fill my ebb and flow tray full of hydroton clay balls, and plant directly in that. I am having two problems, the second of which I really need some advice on:
First, a statement:
Clay balls float!!!
Ok here are the problems:
1) The clay balls float - and they float right into, and clog, the overflow. I need to rig a screen over the overflow.
2) The clay balls... float!!! If I let it fill to the overflow, they all move sort-of like wet cement. Is this good for the plants to have the medium moving like this, and then re-settling, with each watering? What advice do you all have for this?
Previously I was using only net cups filled with clay balls, and I think the walls of the net cup kept the balls in place. But now it's like they are floating in a big bathtub.
I really need to decide what to do and get the tomatoes planted by tomorrow so any input is GREATLY appeciated :)
