Welp-

1st off, remember that EC is relative- some forms of N are more conductive than other forms of N,etc...

There are also matters of dilution- fer instance, using the Advanced SG two part, 5/ml a gallon of each will give you an EC of right about 1.0, while doing the same volume dose w/ each part of the Canna will, as I remember, put you right around .7. ( Base nutes, no addys).

And 10/ml of, say, Cornicopia will put you at about .8 , but this will fry the living hell out of everything. But I've pushed Pure Blend Pro up to like 2.1, without any problems.

It's a relative measurement- it really just tells you how well a solution conducts electricity. From there you can measure the relative concentration of a solution, but it really only compares cleanly w/ a more or less dilute volume of the same solution.

But yeah, there's a "cost of nutrient over time" factor- sometimes the stuff that costs a lot for a little bottle is cheaper long term than the stuff that costs a little for a gallon jug. Depends on how fast ya use it up.
rhizome Reviewed by rhizome on . N-P-K for the Ladies As of now I have Fox Farm nutrients -Grow Big 3-2-6 -Big Bloom .01-0.3-0.7 -Tiger Bloom 2-8-4 I read on another site that 20-10-10 or 20-10-15 is good for young plants. Using Fox Farm how could I get those numbers? Is there another brand that would be better? I've been reading about Super Natural and they seem to have some pretty good reviews. Could I use the Fox Farm solutions with CalMag+ and Liquid Karma? Thanks in advance! -Colour :S5: Rating: 5
