Nutes are like cars,
everybody has their favorite brand and model.
I have only tried Advanced Nutrients and Dutch Master.
Both work pretty well
but the DM was outrageously priced and hyped.
I am growing with AN Sensigrow for veg,
and AN Connoisseur for flower, from now on.
I have fantastic result with AN nutes at 50% loads.
You may think AN nutes are expensive,
but you can cut the amount in half and save money,
without compromising the yield of your grow.
I have never tried the GH nutes,
and I know they are inexpensive,
and have been around for years.
I have had such great success with the AN nutes
that I am not willing to take a chance on growing for 4 months
to find out the GH nutes aren't what I was expecting.
Maybe someday,
I will do a side by side comparison grow,
between AN and GH.
In the mean time,
I will stick to what I know.
The AN nutes works outstandingly well @50%,
in my aero system.
Just my biased opinion.
