Seaweed Extract with Hydroponics

Concerning the hydroponic nutrients, I wonder if "seaweed extract" can be used in hydroponic systems. If applicable, what precautions should be taken?

Seaweed extract-darn good so far!
by: Digidoc

I have been using Seaweed Extract in my small hydroponics systems and so far the plants seem to be loving it. As posted earlier, the extract has basically all a plant needs (except some suggest adding a touch of magnesium sulfate to the system) and it is often a cheaper, single solution than all the mega products commonly advertised. I am not sure for large systems, but for my little hobby growth lettuce and greens it works great!

Seaweed is loaded with nutrients

Seaweed extract contains large amounts of phosphorus, potassium, nitrogen and trace elements...everything a growing plant needs. It is a key element in an organic nutrient mixture containing blood meal and fish emulsion so if you wish to 'go organic', by all means, use it.
