sounds nice! ya IDK even where to get urea, but the rest looks good, might have to try this sometime soon! My PH is always lower than 7 so this should be a good trial..Thnx Happi for the post!
Andrew you can buy a urea from ebay very cheap. 1 pound for $6 shipped on [Ebay Link Removed] you might need to buy Mg nitrate and Ca nitrate i know GLA carry them.
