11 bottle system

[tfrost2002]

I decided to give this a try starting with tomatoes and have attempted to build the 11 bottle system of Ron's. I haven't started actually growing yet I'm trying to work out the kinks first. The bottle caps leak. I have tried several types of glue, silicone and such but no matter what I have used with the soda bottle caps some leak.

In the pictures(of Ron's system) the bottles are white and seem to be constructed in a way that would seal better than with the bottle caps. I would like to know how those bottles where made, are they painted, if so with what type of paint? Is it possible to buy those bottles somewhere?

I will likely be asking many questions and appreciate your patience and help.

Thank you.
