CGI..
Let's just say,that I always wondered! So.. I just tried it with success.I might add. Thought for a minute I kiled her. Just started with oxygen being the primary ingredient other than ph'd water in the res. Still needed something I'm sure cause it was shocked like hell!

From there just went to 1/4 strength nutes. I've only changed the res. 3 times. When I clean it I empty the res and dry it with a towel.Then spray 10% bleach solution, Clorox,in the bucket and let it sit and towel dry or rinse with water,then towel dry.

Fill it back to fill level.
Now I'm up to full strength now.

Ga.

P.S. I still like DIRT the best! But it's fun Tweakin' the project.If I get it figured out? Who knows.
