  • Cheers - seems there are multiple things I could have done. I would rather avoid having to do a reprint, but it may be necessary.

    Upon closer inspection, I think the geometry of the bottom part is designed in such as way that it comes out with a lot of cavities (it is slanted, requiring multiple steps). It could be that it will be very difficult print properly to begin with.




  • I personally would not consider superglue harmful enough to worry about plants seeping enough of it to affect the health of me eating the plant, and it’s not food grade. I’ve used it to fix cracked humidifier reservoirs in a greenhouse for example.

    I would want to avoid something that leeches off into the water. That said, I am going to dilute it quite a lot since the stuff will be very concentrated. Super glue could be a little expensive for this though? I think coating the whole bed would take multiple small containers.

    That being said, most epoxy resin dries food grade. I don’t think you’d have to search hard for a very well performing Resin with food grade search term swapped with dining surface or some frequent use that requires food grade.

    I know very little about epoxy resin, but that is what I often see - but is it really basically the same stuff that is used to repair boats as people use for decorations? The safety data sheets for the components are always pretty rough, but they of course say nothing about the cured state.








  • “1kW within 1hr” isn’t power. That’s energy.

    The watt is always power, not energy. I’m assuming OP here got some prepositions mixed up and meant 1 kW delivered for 1 hr. That amounts to an energy of 1 kWh.

    The second is like hell hole, tons of energy but still only a little bit of power.” No. They are both precisely the same energy.

    No, they are the same power. The energy in the case where 1 kW of power is delivered for 1 hour is 1 kWh. The energy in the case of 1 kW delivered for 1 s is about 0.28 Wh.

    If instead 1 kWh was transferred over the course of 1 hour, that is an average power of 1 kW (but does not have to be uniform, without more information we can’t know the power profile). If 1 kWh is transferred over the course of 1 s, that is an average power of 3.6 MW which is the example I think OP was getting at (ref. hell hole comment).
