the pf style jars with brown rice flower is the only substrate you do need a pressure cooker for... you don't need one for bulk substrates but you will need spawn...which needs a pressure cooker,
and even with pf tec pressure cooker is recomended... and it needs to be able to get to 15 psi...cost about 130-200$ for a small AllAmerican metal seal PC
