I have 54 hooked up and I have gone through about 2/3rds of my 30m roll. Your mileage may vary depending on how far you plan on placing the blumats from the feed line. For reference I run my feed line around 3x3 tables, and then run the drip line from there in. So the furthest my drip lines go is probably 22 inches or so. Most are only about a foot long.
