You can get the circle saw drill bits at lowes/home depot/online... They usually come in kits w/ 1/2" - 2 or 3" circumfrances and are pretty cheap.

1-2" squares 6" - 8"+ tall reccomended. If your growing from seed keep in mind males. Might be best to sex then squish the screen overtop. Adapt/scale to your space and you should do fine :thumbsup:

And your welcome. :twocents:
