can you grow in a flood system using nothing but 1/4in rockwool cubes. just alot of them? i need hydroton but where i live its almost impossible to find and really expensive, any suggestions?
You can find it on E-Bay. That is where I get all my stuff. No hydro stores less than 2 hrs. from where I live. Just be decreet(SP) and use cash or money orders. If possible us a friends address for deliveries. Though I have never had a problem.
