I check and GH does not sell their 3-part in powder form. There are a few sellers on ebay that offer free shipping and a quart of each will last you a full grow and then some.

Joel do I have an email for you???

I think so zandor at pot.com

drop me a line before you order any nutrients or ph products. I can pick up a quart for you of each of them and just add the cost to the system. I don't think it will change the cost for shipping at all now that I think about it.

We can't buy nutrients wholesale yet but working on it.
