Hi guys Have you ever tried using kelp/seaweed? I came across this company called www.SeaNutri.com They are 100% Organic and their product was developed by Pepsi and sold off in India and now they are here. I saw they are listed on Driscolls and, Kellogs started testing it. We tried some on a few of our hydroponic plants and wow it accelerated everything tremendously! If you contact them as a grower, they give free 1lb samples and because of its high potassium concentrate it can last for a whole harvest ( I believe) on a small plant for testing. Just want to share this with everyone, organic is the future!
