Hi i soon come to install/build my botanic cell /
greenhouse bed in my Earthship. But i can not find locally EPDM liner only pvc. And only in 0,5 and 1mm thick the old book recommends a 2mm EPDM liner. Any in here have
experience with using PVC liner will they last ? are they toxic ?
If any know were to buy a EPDM liner in Portugal ore west Spain i´m all ears. (
online order is not that easy since it´s a 80 kg packed, )
