is this foodsafe? Would it leach into foodplants if used as a pot, and would it leach into food if used as a cooking/serving bowl?

Although it’s an organic mix of Portland , peat moss , and perlite, Portland has naturally occurring metals like aluminum and iron. I don’t know how much, but I know it’s porous and leaching occurs throughout the lifetime of any Portland mix. I definitely wouldn’t grow a chelator herb like cilantro in it.if you’re trying to limit your heavy metals exposure. Note heavy metals occur naturally in our environment and our soil. These are organic materials for growing though. I’m a little more finicky about my food chemistry and the nutrients that I build into my food crops so these pots are not food worthy for me, but it’s really a matter of degrees since this is organic materials ( that do leach bc of their porous breathable nature). Some people add fiberglass for strength and that is completely unnecessary as they can withstand freezing temperatures if cured properly and excessive amounts of water isn’t added. Any you tube videos where people are mixing a liquid pour will crack in winter. Less water is best with Portland and a handful of fine sand adds strength. The peat moss allows expansion and weakens strength, so very cold temps store in a garage in winter or pack hay around it or any insulation. Perlite wicks moisture away from roots, vermiculite holds water. Pure Portland is best for cold temperatures, but for the natural look with PM and perilite , just insulate. Otherwise your Portland without the additions dries white. Every region has a different Portland mix that is appropriate for temperature of area. All Portland mixes are not the same geographically. Some have more silica than others etc. a handful of fine sand will always improve the bonds and strength.
