Seacrop what are your thoughts?

[EclipseFour20]

Sea90 for root/foliar spray, I add 5ml/gallon--ground finely.

As a soil amendment, I add ground Sea90 to the custom grow mix at the rate of 1/2 lb/cu yard (equivalent to about 8.4 grams per cu foot)--which coincidentally is about 50% of the rate for "land minerals" (epsom salt & rock dust).

When you say 50% of "land minerals", do you mean 50% of the average of naturally occuring levels, or 50% of the levels occuring in your personal medium? Or..??
