Anyone know the cup measurements to make 8 brf cakes?

Im starting a my second grow, first being GT, and pretty successful for a newb. I only have 6 1/2 pint jars currently, then going and picking up 10 more from Wal-mart, and to do it evenly im doing 8 Ecuadorian, and 8 Cuban. i found the recipie for 5 cakes, but i need a recipie for 8. If anyone can help me out id appreciate it!

Thank you, but how do i get the measurements for the last 3? i dont want my substrate/water content to be off

 

youll have to make as much as you do for more, and throw away the left over. its really the only way to get water ratio correct.

 

alright, thank you ill give it a shot
