Using a Screen #2 - Increase Yields

I first was introduced to the idea of growing with a screen from an E-mail from a good grower that was looking to increase their yields.
I have previously talked about using a screen to grow in small spaces.  A friend of mine is doing this now so I'd like to add some comments.
First, I mentioned in the using a screen article that you should trim lower branches and leaves to avoid them becoming infected with mold.  This is still a good idea, but my friend has not had any problems with mold and she does not trim the branches.  She does remove all yellowing fan leaves.  She says light getting to the plants is more important than the nutrients that are left in the yellow leaf.  I still say it is not a bad idea and you could use these lower branches for cloning.  The advantage to using these lower branches for cloning is you can pick the plants that are doing the best or have the best characteristecs (growth habit, color, taste etc.) 
Second, I recomended using chicken wire or small holed fencing in my first article.  My friend really likes the fencing where there are square 3x4 inch holes.  She said the chicken wire holes were too small, it was hard to get the stems through the wire when they had big fan leaves, and it was easier to train the brances with the larger holed fence.  She does not even use tie wire etc.  She simply keeps the plants growing along the screen until the plants really start to flower, then the plants stop their vertical growth.

I welcome any other commets about growing with a screen,
Good Growing,
