you are mistaken sir.
Totally true. The carbs you are adding mostly help out with benefitial microorganisms in the soil. Hydro systems should be mostly sterile or at least very controlled when it comes to microorganisms - no real point in adding it in that case. I hear it gums up sprayers... as well.Molasses will work in soil but not hydroponics as plant cannot break down the complex carbs in the molasses it self. This is from year 1 college botany text book :/
