Economical nutrients

Jack's 3-2-1 setup. if you buy in bulk it's roughly 4 cents per gallon mixed, even with recent inflation. Used to be well under 4 cents per gallon, lol. but, you gotta buy in bulk, so 25lbs bags. you spend a bit more upfront but it'll last several years for a small garden. dry nutes store indefinitely, so that is not an issue. jacks 5-12-26 Part A - 50-70 $ 25lbs. enough for 3700 gallons? can do the math 25lbs converted to grams / 3.6g dose. Calcium nitrate -- this can be generic or jacks... 30-50 $ range epsom sale (magnesium sulfate) -- 8lbs foodgrade walmart equate brand is 8 $. spend 150 or less today and won't spend money on nutrients for at least 3 years or longer. if you do 30-40 plants/year it's maybe 25-30/year in fertilizer. you can't beat 25/year growing year round with 30+ average-sized plants in total.
