Blocking roots with a screen?????

I,grow in diy tubs that use a pvc manifold to spray onto the roots.
A hose runs down through a hole in the tub to the resvoir and pump.
In the past my tubs were big enough that i could handle the roots growing down into the res. As long as i look the pumps and move them away from the roots from time to time..


Well now im in smaller tubs and resevoirs with less verticle space.

I was wondering what would happen if i pulled the root mass up into the top tub and laid a piece of screen across the hole....

How might this affect my growth?
If they cant grow down, will the roots still grow since they're still getting wet?

First one is my current setup.
Others are previous grows to give you an idea what i do

If water can get through the screen, roots will grow through it too.

Yes. Thats what happened... Im thinking maybe next grow i can find a way to train them...
Maybe some inserts that will make them grow side to side on a series of declines.. At least give me more time in the root chamber and take longer to hit the res.

If you find something that works, lots of people will be wanting to hear about it!
