Ted / Barry- which products are your investigating? I have used a few and may be able to help. I mentioned earlier we are going to see what happens with the Holganix and SumaGreen Turf then of course the fertilizers we were using also. I am hoping that the SumaGreen Turf is going to at least do the same job considering its price is cheaper (per treatment) then Holganix.
Right away for me anyway the biggest difference is going to be the sprayer and not having to worrying about changing spray volume with SG Turf. From what I heard from my buddy you have change spray volume with Holganix. SG Turf seems like less headaches. I would be interested in knowing more of the products your were testing.
Barry have you used either in the past?
