Press is here how many seconds should I be pressing for lads
That's very cool that you have your own press. Have fun. In terms of press time, some of it certainly depends on the material you're pressing. No question. I like to press a couple of grams a few different ways to figure out what I want to do with a run. But, there are general observations too.
1. The longer you press and the more times you press (e.g. repressing after a blowout), the darker your rosin.
2. Some strains yield a very consistent rosin, whether you press for 30 secs or 180 secs. Others will give you something nice and light and creamy right away and then darken up. For those strains that offer a nice cream off the top, I'll have a second piece of parchment ready and drop my puck onto the 2nd sheet after it's given up the cream. I've not really done any kind of side-by-side comparison on the smoke from light v dark (except maybe for Green Crack, where I really like the dark + it's a bit more shattery). Right now I do it mainly so the owners of the rosin have an option for their own use or market prefrence. If I then repress, I'll usually fold my bag in half (longitudinally) to maximise extraction from the centre, reserving that (on most occasions) for edibles.
3. With kief or bubble, higher temps (e.g. 220-230) will give you more of a squirt. This can be useful if it's a material you want to press quickly (usually to avoid a darkening). Of course, this needs to be balanced against a possible greater loss of particularly the low molecular weight terpenes. Most of the time, I press kief at 180. Low and slow.
Good luck.
