you only need one of the plastic strips for a 4g kit.
OK I have a 4g finakit and some vet america T-H component. I have 2 carts each one is a 20 dose cart for heifers LOL. I think I only need 1 cart of the T-H to make a 4g kit (they are much longer than the H carts. I know it takes 2 H carts to make 1 4g bottle but I am pretty sure it does not take 2 t-h carts. I have looked for this extensively and have had no luck in finding out an answer. I just want the concentration to be right. Please help if possible. Please assist if you have an answer.
