lost I just read the whloe tubgirls thread(great thread, pre mpb), but I couldnt find where you mention what size drill bit(hole saw) you used for the grommets.
u dont by chance remember off the top of your head?
thanks my friend... if not no worries.
I also plan on taking ur advice on the ebb and flow fittings u posted earlier, I just have some extra grommets I never used laying around, just wanted to do a little experiment, but when I do my 4 plant set up eff and flow all the way:smiley_joint:
