obviously you don't read my posts. I am an ex technical rep for AN. I own a hydroshop. I distribute specialty niche products. I am an ex snake oil peddler gone straight.. I have used:
peter's, jacks professional, osmocote, super grow/bloom 1 part powder (white can w typewritten label back in the late '80's) then on to their SVA/B liquid 2 part, supernaturals, GH flora series, lucas, MB, Floramato, FNB, Nutrilife heavy harvest 2 part, ALL AN liquid fertilizers including their "Super Nutrient" line (supernaturals aqua, terra, formulas) Ionic, CES, Canna, B'cuzz, botanicare, earthjuice, foxfarm, Rock, Technoflora, DNF, and I'm sure I'm forgetting a few. Heavy 16 sounds like the real deal too and can't wait to try it.
Fertilizer is 1-10% of the equation. enviro, water quality, and root health are going to do the most for plants. you can feed a plant the bare esentials and as long as the PH is in an acceptable range, it will bloom jut fine.
everyone is just stuck on marketing hype, or has a friend that grows the best weed on the planet and he uses this and that blah blah blah. They all work. I like the dynagrow Bloom because with tapwater I use very little. 3-4ml/gal.
concentration and having all 16 essential minerals are important for me. if I'm going to buy water w salts in it, it better be stabile and require a very low dose.
