Got some free nute samples, got a few questions.

Hi guys, so I went to a local hydro store the other day and got some free stuff from the guys there.
The first 2 items are some nutrient smples called dutch master
One of them is called Liquid light, apparently some kind of foiliar nutrient spray, which is supposed to maximize the plants light useage.
Stats on this one are 0-0.2-0.2 and it is apparently derived from monopotassium phosphate, potassium sulfate, magnesium sulfate, and iron EDTA
The other is called Saturator, which is used in combo with the liquid light in order to help the plant absorb the spray. Stats on this one are at 0.008-0-0.003 this one says its derived from potassium nitrate.
And last is something I've heard a tiny bit about called Great white. I guess its a bunch of beneficial bacteria and trichoderma for adding to soil for better roots.

My questions being, I wouldn't mind using this stuff, but has anyone used it before? Did the resluts come out good? Is it worth using this stuff at all? Or does anyone have problems with it?
Thanks for reading.

The great white is a wonderful product that feeds the root zone. Must be 100% organic to use it.

Oh ok, well I'm using ffof at the moment so I assume that means I should be fine?

i use liquid light and penatrator i mix with a skench of food and seltzer in place of water me and my plants love it

LL liquid light is a foiliar additive that seems way over priced for the results. i pay 60 for a qt and forgot what the penatrator cost but overall i would say its more of a gimic than a light miracle.

its nice to see them giving samples but thats about all you should use is the sample

I see, well the guy at the hydro store matched a bowl with me and ended up saying he'd kick me down more samples whenever if I wanted to keep using it without paying, but if it gets decent results I might try it for a grow.

I've still never really tried foiliar feeding yet, so I think I should do some more research before I jump on into it.
Thanks for the comments so far.
