Dutch Masters Saturator... Anything Special About It?

I have had several people stress the importance/benefit of using DM Saturator. I was wondering if it is anything other than a simple surfactant. I have some agricultural grade surfactant in my shed, 3 gallons for about $150 if I remember correctly; I may be confusing it with another product. I'm not looking to spend $20 per liter on something I already have. Does anyone have any thoughts?

Foliar spray? Do your roots not work?

That's not what I asked...

Better to donate to charity than unnecessary growing paraphernalia

Surfactants ARE useful. It's just Saturator is a hell of a lot more expensive. One 1ltr bottle of Saturator costs as much as 5 gallons of the generic agricultural grade surfactant that I already have... I'm asking if there is anything different about it... not your opinion on foliar spraying or whether you think surfactant is necessary. Thanks. If I wanted to get a bunch of irrelevant non-answers I would have posted in the spirituality section.

if u wer you id just go with what you have on hand.. why waste ur money on something u already have on hand.

Thanks BigBaby, that's what I've done. I just didn't want to miss out on something crucial. I keep reading how Liquid Light MUST be used with Saturator (Penetrator). I asked the guy at the shop today and he called it a wetting agent, which is what some people call a surfactant. Just wanted some other opinions thanks.

I think the marketing point they use for saturator is it can be sprayed while the lights are on. I use sat and liquid light and am very happy with it.
