I use a frenchpress...but still lose limonene in the cactus.  Is there a trick to avoiding this?   I put 300ml in.... let it sit for a day and then press the hell out of it until no more comes out.  I usually end up with 250-275ml of limonene... However, this time I only got 220ml out and I can't press another drop out.

Kemist posted once that he put anyhydrous epson salts into the mix and that helped.... I will try that after my final limonene soak on this batch. 

Any thoughts?  How much limonene do your friend retrieve?
