Good deal for hydro supplies or not??

I was just wondering if this was a good deal or not....? The reason I ask, is I'm not sure how many feedings this amount of nutes will be good for.

It all depends on how many tsp/tbs it take per gal. Usually if you click on the product and scroll down a bit it will show you the lable, and amts used per gal. I'm pretty sure one pound of powder will make many, many gals of solution.
