Intriguing, thanks for the reply, I assume the hydroponics is also offers some sort of lubricant to the cooling system. I know that traditional antifireeze will gum or eat up some metals over time, but it seems that something is better than basically nothing, specifically to a low use or stored engine. I would think that a drained system would lead to siezed pumps and internal flaking to the cooling parts, and now I am way away from the topic. But, thanks for the input.
