Question RE: viscosity in water....I've heard people mention putting dish soap (a drop or two from what I understand) to make the water more "viscus" How exactly does this end up helping the plant?


BTW great thread. :-]

Thank you!:mrgreen:

That's a really good question! Water has surface tension. Dish soap is a surfactant which has chemical properties that increase the surface area of water and decrease the surface tension. Surfactants have a couple of uses for us growers. They are used to prevent water from beading up and just rolling off the surface of the leaf when applying foliar feeds and pesticides. They also increase the lateral movement of water in the soil, thus wetting dry pockets and helping increase nutrient and water uptake. I won't go into the science behind it all but I will post a link so you can do further reading if you'd like.bongsmilie

It's an old school remedy. I prefer to use something like sm-90 which is an actual wetting agent. Back when I started growing we didn't have wetting agents and all these nutes and air cooled hoods. I love progress!:weed:

As long as it's a reverse osmosis filter, yes, it should take care of all of that junk.bongsmilie
