Glad to hear that! There is quite a range of hydro nutrients to pick from, but eventually I chose the GH Maxi series for my first real effort at a hydro project.

It's always good to know there are others out there using the same, will keep posting as this progresses.

I use the Verti-Gro I'm using the 6-12-28 with trace minerals and the 15-0-0 Calcium Nitrate

I found a simple solution for cheap Lettuce nutrients
Just find a professional producer and offer to buy some nutrients.
I can get dry nutrients at 6 euro a pack in the exact proportions for Lettuces. This is enough for 25 changes of my 40L recipient (50 weeks).

Considering prep time as a factor, mess, expense of various measuring equipment, I found CNS-17 Grow to be the most cost efficient for me.

I would consider a dry nutrient if I had to pay for shipping. Since I can buy CNS-17 local and there is no state sales tax, it is the most trouble free and efficient solution I have found.

Halfway,

What do you mean by prep time, mess, and or expense of various measuring equipment?
