SOAK PLUGS FOR 24-HOURS BEFORE USING IN A MILD SOLUTION OF ACTUAL NOURISHMENT YOU WILL BE USING. I USE EBB & FLOW AND DRIP SYSTEM AND NEVER HAD A PROBLEM. THE PLUGS ARE ROUND SO BE SURE THE PLASTIC TRAY YOU PLACE THEM IN IS ALSO ROUND. DO NOT USE A SQUARE TRAY. DO NOT FORCE MACRO PLUGS IN TRAY(S) AS ALL YOU NEED IS SLIGHT PRESSURE SO REMOVING THEM WILL BE VERY EASY. IF YOU REMOVE THE PLUGS AND THEY DO NOT TEAR THEN RE-USE THEM AGAIN. AVERAGE PRICE PER PLUG IS 25 CENTS WHICH IS IN MY OPINION WAY TO HIGH. CALL ME IF YOU LIKE MAC (413) 285-8855

Sales page says "Perfectly fits into the Grodan Gro-Block hole for easy transplanting". I say BS.
