growing hairgrass in a spare container.
I fashioned this thing out of an old water treatment bottle, an air hose and an airstone.
this setup right not is only temporary. i just wanted to get some co2
in there NOW while i finish building the thing.
Im going to head to home depot when it opens here on the west coast go get a suction cup (one with a hole in it so i can zip-tie some sort of clear cup to it.
WHAT CAN I USE TO SET IN THE WATER TO CAPTURE THE CO2
it has to be small and see through. not exactly clear, but it can't be opaque. and i have to be able to zip tie it to a suction cup.
