nutrient longevity(spelling)

Getting ready to try my first grow using bubbleponics system. How long can I expect a three part nutrients in quart bottles to last me? Sorry if this has been ask already, couldn't find where. Thanks for any info,

Depends how often and how much you're using. As a beginner you're going to waste a lot.

That's a bit tricky to tell without knowing size of your buckets, number of your buckets, what product will you be using, how long do you plan to veg or what product will you be using (and whats its recomended dosage). Once you get all those numbers, its a mater of elementary school math to determine how much nutes will you be using.

Or are you asking what's the shelf life of the nutes (then again, that can hardly be answered without knowing the product you'll be using).

Like others have said, hard to answer that one. My only suggestion is to not start out mixing at the levels indicated on the bottles and keep it less and check EC/TDS levels. If you do that you wont waste as much.
