    Ok. I just did a quickie squish. Began with 1.75g of good bud, pressed twice (folded puck over and press again on new parchment paper -- but I do not mix the two batches). The first batch I do at 200 for 150s Second batch at 224 for 100s. Harvested .49g of what I define as smokable rosin (relative, I know). Hence, a 28% squish.

    I've only used 115m bags thus far, but it certainly decreases yield. The question is and remains, is the additional quality "worth it"?

    When pressing more than a few grams, filters increase yield by holding the plant material together. The amount held in the filter is negligible unless you are only pressing 1-2 grams. Then .1 matters.

    Filters will only hurt yeild if you don't fold them inside out to prevent external seams. This is hwy I use bottle tech style filters, no seams.

    Interesting. And makes total sense to me. It's a scale issue. I can wait to try a bag using the full 2x3 plate dimensions which would seemingly be ideal. As I understand, the bag itself "costs something" and therefore the batch size has to be sufficiently large to make it worth it. Is that correct?

    Well ya the bag's around 1-2 bucks a pop so i do like to press as much as I can. This is why slow bottle tech is so great, small footprint and you can go slow to maximize pressure vs heat. But the seams of the bag around the square will hold wax, this is where the loss will be. And why circle bottle tech is best.

    As in this vid? Makes sense. More uniform pressure without going too hard

    @LabPonget al.... look what came in just now for my (our) press? :love:

    Will report back how it goes.

    Just tried it. Many advantages. Good yield of about 22%, but really clear and tasty.
    Makes me question the pre-press purchase? But nevertheless, I'll fiddle about with it. :)

    You can use the prepress to make flat rosin pucks, or initial tiny pressure to just make the bag small enough. But otherwise, ya, no reason to buy a pre-press :)

    EconMan....what kind of temps and times have you been pressing......say smaller squishes like 0.5 to 1g?
  • EconMan

    I would do 195 for two minutes. (and I am a proponent of repressing -- I fold the pucks in half and then repress.
    Remember to press down s l o w l y. If you find yourself pressing really hard, then that is too hard. There is a little nut by which you can adjust how close the plates get (to accommodate big and small squishes). Should be fine for small pressings the way it is shipped.

    I'm experimenting with micron bags today and will have some interesting results to share. In short, I got a great yield using a 4g bag just now, but I used the "bottle tech" method discussed above by @Gman

    Cool thanks.....I did the first one at 205 for 110 seconds.....I will try dropping that temp down and see what happens. I need more time to prep some flower with proper moisture first.....I must get 25% yeild....lol

    Yes. Humidity is important. I use 62% Boveda's in my "for-pressing" flower stashes. As you start pressing you'll quickly see how flower quality impacts actual yield (what you're able to dab).

    Yeah, experiment. Like I said, I'm tinkering with micron bags right now.
    I am averaging about 23% across my batches (for the math nerds - sd=2.1), although once I got 33% but it was nasty -- I must have over pressed it? Regardless, the better strains give the better yields. Indeed, that's how I evaluate flower now -- how well does it press?

    I agree humidity is important. I use a simple way to evaluate the bud.I just feel how sticky the bud is, the stickier bud presses better. Also fresh bud is better imo.

    The clamp press could be improved with digitally temperature controlled plates which wont burn your rosin. Hair straightener plates are way too hot.

    I know this is an older post and you've since upgraded, but any tips on best settings to start?

    I know it's most likely my material, but I'd be really happy with 10% yields.

    On that press, and in that context (no bag, just smash a nug) I prepressed first. Then I would set it to 200f, and press for 2.5 minutes or as @Dr green thumb instructs, "listen to the squish" (seriously! when it stops hissing it's time to take it off. :)

    In this thread I have a lot of successes and fails with the M800. I still use it today. A lovely little unit.

    Thanks for the reply! Was there an amount you felt was a best case scenario?

    My friend....do not at all be happy with only a 10% ROI. Settle for 17-20% minimum....and know you will get more at times.

    The M800 works well....though you may have to press more than 1 time to get it all. I do not ever go over 203F with it. Usually a 30 second preheat with barely any pressure ....just pressure it down a bit to create flat spots on it. Then go 2 mins max.....just go slow....little pressure at a time. You will actually be able to feel it giving way and collapsing under a bit of hand pressure. Let it soak heat up for 15 seconds at a time before you apply more pressure and go slow until you feel it sort of stop. The last 30 seconds left I just usually lock it out.

    If you repress the chip...break it into 2 or 3 pieces and stack on top of each other....then do the same press technique again. Sometimes I press 3 times at 193F...but it all depends on the flower and what she gives up for you.

    That is how I use the M800. You can feel what is going on most of the time after you practice some. Flower humidity is important, as well as getting flower that is good for pressing. Select the densest flower you can find....an indica obviously is more in this direction.

    I'd love to get above 10%! I think my flower isn't the best for rosin even though it vapes well via a dynavap or PAX 3. But, it's all I got until my next grow.

    Any recommendations on what weight puck to use? I have one of the small 3/4" cylindrical presses...

    Even some of the best erb can only produce 13% with rosin extraction. There's so many factors involved.

    I do not use any pre-press mold deals. I just pull the buds out of a 52% humidity controlled container...weight out what I need....then form the bud/s into a slightly compressed shape with my fingers.

    I do not like crushing all the trichomes ....i rather keep them intact and then heat up and quickly press.
