Peanut butter pretzel container sleeve for passive hydroponics
thingiverse
Fit this sleeve and lid around an empty Kroger brand peanut butter-filled pretzel container to block out light so that it can be used for passive hydroponics (commonly referred to as "Kratky") without growing tons of algae. Includes a slot on one corner to monitor water level. Drill a hole in the container lid of whatever size you need to fit a [net pot](https://www.amazon.com/inch-Pots-Super-Heavy-Design/dp/B073WJ78MM?keywords=3"+net+pot&qid=1677457502&sr=8-9&linkCode=sl1&tag=reeall-20&linkId=f6e24b6136033390933f4404724bbf18&language=en_US&ref_=as_li_ss_tl), solo cup, or whatever, using a [hole saw](https://www.amazon.com/inch-Pots-Super-Heavy-Design/dp/B073WJ78MM?keywords=3"+net+pot&qid=1677457502&sr=8-9&linkCode=sl1&tag=reeall-20&linkId=f6e24b6136033390933f4404724bbf18&language=en_US&ref_=as_li_ss_tl). Print using any kind of black filament. The whole point is to block out light so using a light color defeats the purpose.
