I press flower at 115*F with a 4 ton press I use a pre-press to make a 2x4 puck with 10 grams of flower. I use a 120 micron mesh bag to press flower. I save my pressed pucks and when I get 4 or 5 I stack them and repress them. After they have been pressed twice I rinse them in everclear 190 proof to make a tincture of sorts I use to make edibles. Grandma said; "waste not want not."
My system has 4ea 5 gal buckets that are interconnected they have 2 or 3 gallons of nutes in each depending on the roots. a float valve keeps them topped up continuously and I replace 2/3 of all once a week. I use Jack's or Peter's Hydro nutes with calcium nitrate and epsom salts in a 3-2-1 dilution.
