Hey tok!

How weird! I'm getting ready to do the same thing! I've got 6 2l bottle cut in half with perlite and vermiculite! Haven't germed yet, my 1st grow's wrapping up and this going to be a side project to my next dwc grow.
I'm concerned about algae, are you? I guess I can rinse them every other day or so. I'm hoping the roots will grow down into the bottom reservoir kinda like from a net pot to the res in dwc. I'm excited! I'll follow your grow if you don't mind!?
