Ok thankyou for your input I'm going to be using the 37u bags I'm going to be pressing some blond Lebanese hash at around 160-170 and hoping to get a nice gold/yellow look with a butter consistencyPressing hash you need to make sure to start with light pressure, let the patty warm up and slowly increase pressure. If you come at it with pressure too quickly then your seams can burst.
The 25u metal screen is by far the best for squishing large amounts of hash. a 37u bag will work for small batches (thinner cakes)
I would get up around 200F, at least 190.Ok thankyou for your input I'm going to be using the 37u bags I'm going to be pressing some blond Lebanese hash at around 160-170 and hoping to get a nice gold/yellow look with a butter consistency
