4) You may need to run another bead of silicon along the edge where the cap meets the fence post. Spread it in with your fingers.
5) Let it dry for 24hrs.
I've never had any leaks using this technique.

i did this on my first system and the inside bead of silicon did not get enough air to set properly. the next morning after set up i had this white sticky froth clogging everything. it took 4 hours to clean everything including roots. i then found a silicon that sets in 2 hours at lowes and it works great no leaks at all. i also was having a leak proplem with the veg and clone units-yes i used rubbermaid. i used this rope weatherstrip from lowes or walmart and used one strip around the outside top edge of the container and have not had a leak since.
