Mr. Wonder,
First off +REP
Some questions please?
How are you watering/changing water for your system? Recirculating system?
What is your floor/lighting (Wattage, Type, etc.?) arrangement?
Any more advanced techniques used? Like FIM, LST, SCROG, anything?
How do you keep the light from reaching the roots? How do you hold the Rockwool in place? Cutting a square in the lid?
Any detailed info would suffice in place of pics I'd think - a picture is worth a thousand words but perhaps enough detail lends credence to your system. I have been looking long and far for something as simple and easy to maintain - would love to discover I've finally found it! If so - could use all the help setting it up on a slightly larger scale.
Thanks Mr. Wonder!
